8 Niacinamide Benefits Beyond the Serum Bottle

Written by Jinfiniti Science on March 18, 2026. Posted in Supplements, NAD+ Precursors, Nicotinamide, Skin Health.

Niacinamide has become the go-to ingredient for sensitive skin, and for good reason. Clinical trials show real improvements in skin conditions ranging from acne to hyperpigmentation to signs of aging. What most people don’t realize is that niacinamide benefits extend far beyond healthy skin maintenance — all the way down to how your cells produce energy and repair DNA.

What You Should Know

Niacinamide is one of the direct precursors to NAD+, which your cells use to create energy, repair DNA damage, and regulate metabolism.
When applied topically at a concentration of 4–5%, it has clinical efficacy at improving fine lines, dark spots, and acne.
It doesn’t cause flushing like niacin, which makes niacinamide one of the most well-tolerated forms of vitamin B3
Supplementation can increase blood levels of NAD+, but less efficiently than NMN or NR if your goal is long-term NAD+ optimization.

NMN + Niacinamide Formula

Four ingredients. One formula. Clinically validated.

What Is Niacinamide? A Type of Vitamin B3, Explained

Niacinamide — also called nicotinamide — is the amide form of vitamin B3. Your body creates it when it converts excess niacin or metabolizes tryptophan. It’s well tolerated by most people because, unlike niacin, it doesn’t cause flushing.

At the cellular level, it serves as a direct precursor to NAD+ (nicotinamide adenine dinucleotide), the coenzyme every cell depends on for energy production, DNA repair, and metabolic regulation.

Niacinamide Benefits for Skin

Niacinamide is one of the most studied ingredients in clinical dermatology, with evidence going back decades. Here are the four skin benefits with the strongest research behind them.

1. Stronger Skin Barrier

Your skin’s outermost layer holds together through a combination of proteins and lipids called ceramides. When this barrier weakens, moisture escapes and environmental irritants get in.

Research published in the Journal of Cosmetic Dermatologyconfirmed that topical niacinamide stimulates ceramide synthesis, reduces transepidermal water loss (TEWL), and increases moisture in the stratum corneum (the skin’s outer surface). It also accelerates keratinocyte differentiation, the process by which your skin continuously renews healthy cells.^[1]

Skin that gets regular niacinamide holds onto moisture better and handles cold air, harsh cleansers, and pollution with less reactivity.

2. Less Hyperpigmentation

Dark spots and uneven skin tone are among the most common reasons people reach for niacinamide, and the clinical data supports this use at concentrations of 4–5%.

A 12-week double-blind, placebo-controlled trial published in Dermatologic Surgeryapplied 5% niacinamide to half the face in 50 women with signs of facial photoaging. Niacinamide produced measurable reductions in hyperpigmented spots, red blotchiness, and skin sallowness (yellowing) compared to the untreated side. It works by blocking the transfer of melanin from pigment-producing cells to the skin surface, cutting off the process that creates visible dark spots.^[2]

A 2025 review published in Medicina confirmed these findings across multiple clinical settings, including melasma and post-inflammatory dark spots, at concentrations of 2–5%.^[3]

3. Fewer Breakouts

Niacinamide does not kill acne-causing bacteria. It reduces the inflammation that makes breakouts angrier and slower to heal.

A 2017 review of 10 clinical studies found that 6 of 8 topical niacinamide studies showed a meaningful reduction in acne versus baseline, and both oral supplement studies did too. Niacinamide calms inflammation by suppressing the release of pro-inflammatory signaling molecules, which helps with inflammatory acne, rosacea, and contact dermatitis.^[4]

Two open-label studies with 198 and 235 patients respectively found that oral niacinamide produced visible improvement in inflammatory acne, with results comparable to concurrent antibiotic treatment.

4. Reduced Fine Lines and Photoaging

The same Bissett trial found improvements in fine lines, wrinkles, and skin elasticity over the 12-week period, making it easy to compare the treated side of the face directly to the untreated side.

Research in Skin Pharmacology and Physiologyconfirmed that topical niacinamide also helps protect against the DNA damage that accumulates in skin from repeated UV exposure. These protective properties, combined with barrier strengthening and collagen support, explain why niacinamide turns up in so many anti-aging formulations.^[5]

Niacinamide Benefits Beyond Skin

The four benefits above come primarily from topical use. Oral niacinamide products work differently, with effects that extend well beyond what you can see or feel at the surface.

5. NAD+ Precursor Activity

Every cell in your body depends on NAD+ (nicotinamide adenine dinucleotide) to produce energy, carry out metabolic reactions, and repair DNA damage. NAD+ levels drop steadily with age, and that decline tracks closely with the functional changes most people associate with getting older.

Niacinamide feeds into what researchers call the salvage pathway, the main route by which cells recycle and replenish their NAD+ supply. Once absorbed, it converts to NMN (nicotinamide mononucleotide) via the enzyme NAMPT, then to NAD+.

A 2021 clinical trial found that a single oral dose of 500mg niacinamide raised blood NAD+ levels measurably within 12 to 48 hours in healthy adults.^[6]

As a standalone, niacinamide is less efficient than NMN or NR at raising NAD+. Both of those precursors are structurally closer to NAD+ and require fewer conversion steps. Niacinamide still contributes, and it works especially well when paired with other precursors and cofactors that support the same pathways.

6. DNA Repair Support

One of NAD+’s most important jobs is fueling the enzymes that repair damaged DNA. PARP-1, for example, responds to breaks in your DNA by calling in the cellular repair team. Every cycle of that repair process uses up NAD+, which means your cells’ ability to fix DNA damage is only as good as the NAD+ available to power it.

By contributing to NAD+ levels, niacinamide helps keep that repair capacity running. A landmark randomized controlled trial found that 500mg daily oral niacinamide significantly reduced the incidence of new non-melanoma skin cancers and actinic keratoses (precancerous skin lesions) in high-risk patients.^[7]

A separate study by Drago et al. found that 88% of patients on 500mg daily niacinamide saw a reduction in actinic keratosis size, 42% experienced complete regression, and no new lesions developed during the study period. In the placebo group, 91% saw their lesions worsen.^[8]

Research in this area is still early, and not every trial has shown the same results across populations. The consistent thread is that niacinamide’s contribution to NAD+ shows up in measurable reductions in UV-related skin damage over time.

7. Anti-Inflammatory Effects

The same anti-inflammatory action that makes niacinamide useful for acne and rosacea operates throughout the body when taken orally. It dials down activity in a key inflammatory signaling pathway, reducing the output of pro-inflammatory molecules across multiple tissues, not just the skin.

The 2025 review in Medicina compiled research showing niacinamide supplementation reduced brain inflammation in animal models of diabetes and Alzheimer’s disease.^[3]

In separate human research, oral NR supplementation (another vitamin B3 form) reduced circulating inflammatory markers alongside improved muscle NAD+ levels in older men, pointing to the anti-inflammatory effects of B3 compounds as a class when they raise NAD+.^[9]

At 250–500mg daily, niacinamide is well-tolerated. Doses up to 3g/day show a strong safety record, with occasional nausea or mild digestive effects that typically resolve when taken with food.

8. Joint Health Support

Most people taking niacinamide for joint health are doing it for osteoarthritis, and there is a small but notable clinical trial worth knowing.

A double-blind, placebo-controlled trial published in Inflammation Research (Jonas et al., 1996) randomized 72 osteoarthritis patients to niacinamide or placebo for 12 weeks. The niacinamide group showed a 29% improvement in global arthritis impact, compared to a 10% worsening in the placebo group. Joint mobility improved by 4.5 degrees over controls. The niacinamide group also reduced erythrocyte sedimentation rate (an inflammation marker) by 22% and cut their use of standard anti-inflammatory medications by 13%.^[10]

The same mechanism at work in skin appears to be at work in joints, with niacinamide reducing inflammatory signaling at the cellular level wherever it lands.

Niacinamide vs. Other NAD+ Precursors

Niacinamide is one of several routes to raising NAD+, but it is not the most direct. It has a longer history, a lower cost, and stronger clinical evidence for skin health than most other NAD+ precursor forms.

NMN and NR raise NAD+ more efficiently because they sit closer to the end of the biosynthesis chain and require fewer steps to get there.

The most practical approach is using them together. Jinfiniti’s Vitality NAD+ Booster combines niacinamide with NMN, creatine monohydrate, and D-ribose, a four-ingredient formula working through multiple metabolic pathways at once. In a clinical setting, 85% of participants reached optimal NAD+ levels (40–100 μM) within four weeks, with an average doubling of baseline NAD+ levels.

“Niacinamide is one of the four ingredients in our Vitality formula for a reason,” says Dr. Jin-Xiong She, founder of Jinfiniti Precision Medicine. “It feeds the salvage pathway, which is how most of your cells replenish NAD+. But whether that actually translates to optimal intracellular levels — that’s something you can only confirm by testing.”

How to Use Niacinamide

For topical use, look for formulas with 4–5% niacinamide. That concentration has the best clinical backing for hyperpigmentation, barrier repair, and anti-aging. It pairs well with retinol, hyaluronic acid, and vitamin C, and is generally well-tolerated for daily morning and evening use.

For oral use, niacinamide is found naturally in meat, fish, eggs, legumes, and whole grains. Clinical studies have used doses from 250mg to 3g/day depending on the application. Because it skips the flushing reaction that comes with niacin, it is one of the easier B3 forms to take consistently.

If you are taking niacinamide supplements to raise NAD+ specifically, niacinamide alone is unlikely to get you to optimal intracellular levels (40–100 μM). The Intracellular NAD+ Test is the only way to know where you stand.

Frequently Asked Questions

Can you use niacinamide every day?

Yes. It is one of the few actives that tolerates daily use without irritating the skin barrier, which is why most clinical trials testing it for skin conditions like acne and hyperpigmentation used it twice daily for 8–12 weeks straight.

Is niacinamide a B vitamin?

Niacinamide is a form of vitamin B3, one of eight water-soluble B vitamins. Because it is water-soluble, excess amounts are excreted rather than stored, which contributes to its strong safety profile at typical doses.

Does niacinamide work for all skin types?

Clinical research has tested it across oily, acne-prone, dry, and aging skin, and it performs consistently across all of them. People with very sensitive skin should patch test first, but niacinamide is better tolerated than most actives with comparable benefits.

Does niacinamide help with fine lines and wrinkles?

Yes, with topical use at 4–5%. A 12-week clinical trial found measurable reductions in fine lines and wrinkles, improved elasticity, and reduced skin yellowing. It works more gradually than retinol but causes far less irritation.^[2]

Can you add niacinamide to an existing skin care routine?

It layers cleanly with hyaluronic acid, vitamin C, retinol, SPF, and peptides. Apply it after lighter serums and before moisturizer. The older concern about combining it with vitamin C has not held up in more recent research.

Are there risks to taking niacinamide at high doses?

At 250–500mg/day, the safety record is strong. Doses up to 3g/day are generally well-tolerated, with occasional mild digestive effects. Above 3.5g/day, some studies have documented liver enzyme elevation and headache. If you are considering higher therapeutic doses, monitor liver health with a healthcare provider.^[11]

Can niacinamide affect liver health?

At standard doses it poses no known risk to liver health. The concern arises above 3.5g/day, where elevated liver enzymes have been documented in some research. This is well above typical supplementation levels, and unlike niacin, niacinamide does not carry liver risk within its normal therapeutic range.

Does niacinamide affect blood sugar or help with diabetes?

Early research explored niacinamide for protecting insulin-producing cells in type 1 diabetes, with mixed results. For type 2 diabetes, animal studies have shown improved blood sugar markers, but human evidence at meaningful doses is still limited. It is not a substitute for any prescribed diabetes treatment.

Is NAD+ Worth It? Here’s What a Genomic Medicine Expert Says

Written by Jinfiniti Science on June 24, 2025. Posted in NAD+, NAD, NAD+ Precursors, Nicotinamide, NMN, Supplements.

The wellness world seems obsessed with NAD these days. Social media influencers tout it as the fountain of youth. Biohackers swear by its energy-boosting effects. Even celebrities credit NAD treatments for their youthful appearance.

But are NAD-boosting supplements really worth all this attention? As someone who has spent decades in genomic medicine research, Dr. Jin-Xiong She wanted to separate fact from fiction. The answer is more nuanced than most people realize.

Key Takeaways

NAD supplementation has solid scientific support for multiple health benefits
Individual testing provides the foundation for safe, effective use
Realistic expectations lead to better outcomes than hype-driven approaches

What is NAD and Why Does It Matter as We Age?

Nicotinamide adenine dinucleotide (NAD) is a coenzyme found in every cell of your body. Think of it as cellular fuel that powers over 500 different biochemical reactions.

“NAD is absolutely important to cellular function,” explains Dr. Jin-Xiong She, founder of Jinfiniti Precision Medicine and genomic medicine researcher with over 400 peer-reviewed papers. “Without adequate NAD levels, your cells can’t make energy properly, fix DNA damage, or keep up with all the repair work they need to do.”

The problem starts around middle age. Research shows NAD levels decline by up to 50% by age 50¹. This decline contributes to mitochondrial dysfunction, impaired DNA repair, and reduced cellular energy production.

The NADH Connection

NADH is the reduced form of NAD. While both molecules play important roles, they serve different cellular functions. NAD acts as an electron acceptor in metabolic reactions, while NADH carries electrons to the mitochondria for energy production.

Your body maintains a delicate balance between these two forms. When this balance shifts, cellular metabolism suffers.

The Science Behind NAD Supplements Actually Working

The research supporting NAD supplementation is genuinely impressive. A systematic review of six major clinical studies involving over 400 participants found consistent increases in blood NAD concentrations ranging from 10% to 150%².

These weren’t small, poorly designed trials. Most studies used dosages between 250-900 mg daily over 8-12 week periods with proper placebo controls.

“What’s most encouraging is the consistency across different study populations,” notes Dr. She. “We’re seeing reproducible results in healthy adults and also those with age-related health concerns.”

Clinical Trial Results

Study Type	Participants	NAD Increase	Duration	Safety Profile
NMN Studies	200+	10-150%	8-12 weeks	Excellent
NR Studies	200+	25-140%	4-52 weeks	Excellent
Combined Analysis	400+	Significant	Variable	Minimal side effects

How NAD Supplement Benefits Compare to the Hype

A photo of Dr. Jin-Xiong She playing tennis

The most compelling evidence comes from physical performance studies³. NMN supplementation significantly improved aerobic capacity in amateur runners, with measurable increases in VO2 max and oxygen utilization efficiency.

But here’s where we need to be realistic about expectations.

“People expect immediate, dramatic changes,” observes Dr. She. “The reality is that NAD supplementation works at the cellular level. Benefits accumulate gradually over weeks and months, not days.”

What Research Actually Shows

Physical Performance:

Improved exercise capacity and muscle oxygen utilization
Enhanced grip strength and walking speed in older adults
Better recovery times in trained athletes

Metabolic Health:

Improved insulin sensitivity and glucose tolerance⁴
Reduced cholesterol and triglyceride levels
Enhanced mitochondrial health and cellular repair

Cognitive Function:

Faster brain penetration⁵ (NMN crosses blood-brain barrier in 15 minutes)
Improved spatial memory in animal studies
Preliminary human studies suggest better mental clarity

Do NAD Supplements Work for Longevity?

Image of Dr. Jin-Xiong She being interviewed

The longevity question is where the science becomes both exciting and complicated. The most significant breakthrough came from a recent 2025 clinical trial treating Werner syndrome⁶, a rare genetic disorder causing premature aging.

Patients receiving 500mg daily nicotinamide riboside (NR) for 52 weeks showed remarkable improvements. NAD levels increased by 140%, skin ulcers healed, arterial stiffness decreased, and kidney function markers improved.

“This trial really excited me because it shows NAD actually reversing aging damage in real people,” says Dr. She. “We’ve all been working toward this for years, but these researchers were the first to get clear proof that fixing NAD deficiency can actually turn back the clock on aging.”

Benefits of NAD: What Research Shows

The mechanisms behind these benefits involve several interconnected pathways:

Sirtuin Activation: NAD serves as fuel for sirtuins, enzymes that regulate metabolism and longevity signaling⁷
DNA Repair Enhancement: Adequate NAD levels support PARP enzymes responsible for fixing DNA damage⁸
Mitochondrial Biogenesis: NAD helps create new, healthy mitochondria⁹
Cellular Senescence Regulation: NAD may help clear dysfunctional “zombie” cells¹⁰

Should You Take NAD? A Genomic Medicine Perspective

This is where individual testing becomes essential. NAD metabolism varies significantly between people due to genetic differences, age, lifestyle, and health status.

“I’ve seen two people of the same age have dramatically different baseline NAD levels,” notes Dr. She. “Without testing, you’re really just guessing at the right approach.”

NAD Precursors vs Direct Supplementation

Most supplements contain NAD precursors rather than NAD itself:

Nicotinamide Mononucleotide (NMN):

Direct precursor to NAD
Excellent safety profile up to 1250mg daily¹¹
Rapid absorption and conversion

Nicotinamide Riboside (NR):

Alternative precursor pathway
Shown to be safe up to 2000mg daily¹²
Longer clinical trial history

NAD injections are another option, though the research supporting oral supplementation is more extensive for long-term use.

Who Should Consider NAD Supplementation?

The research suggests these groups may benefit most:

Adults over 40 experiencing age-related energy decline
Athletes seeking improved performance and recovery
Individuals with metabolic health concerns
Those interested in science-based anti-aging approaches

However, Dr. She emphasizes caution: “Supplementation should always be based on the actual need, not assumptions. Testing provides the roadmap for safe optimization.”

How to Boost NAD Safely and Effectively

Current evidence suggests optimal NAD dosing varies by individual goals:

General Health Support:

NMN: 250-500mg daily
NR: 250-500mg daily

Athletic Performance:

NMN: 300-600mg daily
NR: 300-500mg daily

Metabolic Health:

NMN: 300-900mg daily
NR: 500-1000mg daily

But these are general guidelines. Individual optimization requires knowing your starting point.

The Testing-First Approach

Jinfiniti’s Intracellular NAD Test measures actual cellular NAD levels through a simple finger-prick blood test. This provides the baseline data needed for personalized supplementation.

“The Test, Act, Optimize philosophy isn’t just our company motto,” explains Dr. She. “It’s the most scientifically correct approach to any intervention. You need data to make informed decisions about your health.”

Safety Considerations

The safety profile for NAD precursors is favorable across all published human studies. Side effects are typically mild and limited to occasional gastrointestinal discomfort¹¹.

However, certain populations should exercise extra caution:

Pregnant or breastfeeding women
Individuals with active cancer (theoretical concerns about tumor cell NAD usage)
Those taking multiple medications (potential interactions)

The Verdict: Cautious Optimism Based on Science

Dr. Jin-Xiong She holding a jar of Vitality NAD+ Booster

After reviewing hundreds of studies and working with thousands of patients, Dr. She’s perspective on NAD supplementation is cautiously optimistic.

The research foundation is solid. Clinical trials consistently demonstrate safety and efficacy¹³. The mechanisms make biological sense. The Werner syndrome breakthrough provides compelling proof-of-concept.

But NAD isn’t a magic pill. It’s one tool in a comprehensive approach to healthy aging that should include proper nutrition, exercise, stress management and sleep.

“NAD supplementation really works – the science is solid,” says Dr. She. “But like anything that actually works, you need to be smart about how you use it. One size definitely doesn’t fit all.”

The NAD hype has some substance but the real value is in the details. Testing your levels, choosing good supplements and having realistic expectations will help you use this tool safely and effectively.

If you want to try NAD optimization start with baseline NAD+ testing to know your individual needs. The science supports NAD but personal data makes all the difference in getting results.

Best NAD Supplement in 2025: What to Know Before You Buy

Written by Jinfiniti Science on May 8, 2025. Posted in NAD+, NAD+ Precursors, Nicotinamide, Supplements.

Step into the world of longevity supplements and you’ll quickly encounter NAD+, a molecule touted for its role in energy production and cellular repair throughout your body.

Consequently, the market is now flooded with NAD supplements, each claiming to be the most effective. This makes choosing the right one a confusing task for even the most health-conscious consumer.

To help you make sense of it all, this expert guide breaks down the science of NAD boosters and provides clear advice on what experts recommend to help you select the best NAD supplement in 2025.

Key Takeaways

NMN and NR supplements effectively boost NAD+ levels, with numerous studies supporting their benefits
Standard oral supplements (capsules, tablets, powders) are the forms most used in clinical research
Measuring your baseline NAD+ levels before supplementing allows you to track effectiveness and make informed dosage decisions
A combination approach with multiple NAD precursors and supporting compounds may boost NAD+ levels more effectively than single-ingredient formulations

NAD+: The Coenzyme That Declines With Age

Your body relies on nicotinamide adenine dinucleotide, or NAD+, for cellular energy metabolism and hundreds of vital processes like DNA repair. The molecule helps power your mitochondria and activates sirtuins, proteins that help regulate how your cells age.

NAD+ levels start declining with age. By middle age, you might have lost 50-80% of what you had in youth. DNA damage, chronic inflammation and cellular aging all contribute to this phenomenon.

When NAD+ drops, your cellular engines sputter. Maintenance slows down. Your body’s ability to bounce back from stress diminishes. These changes contribute to many familiar signs of aging, from decreased energy to cognitive changes.

Supplementation with NAD+ precursors (the raw materials your body uses to make NAD+) offers a potential strategy to fight back against this natural decline.

Benefits of Boosting NAD

The benefits of NAD supplements appear strongest in people with specific conditions or naturally low NAD levels. This is why we recommend testing your NAD+ status as a first step.

So what specific benefits can you expect when you restore your NAD+ levels? The evidence is compelling.

Studies show that increasing NAD may improve metabolic health. One study of prediabetic women found that taking just 250 mg of NMN daily for 10 weeks improved muscle insulin sensitivity.¹

For active individuals, NAD+ supplementation can improve aerobic capacity, with research showing performance benefits that increase with dosage.²

Your heart stands to gain significant protection too. Clinical research demonstrates that raising NAD+ levels helps combat various heart conditions, from atherosclerosis to cardiomyopathy and heart failure.

Brain health benefits are equally compelling. NAD+ supplementation reduces neuroinflammation, protects neurons, and improves cognitive function by supporting mitochondrial health in brain cells.³

Boosting NAD+ can also reduce chronic oxidative stress and inflammation, both of which are linked to aging and degenerative diseases.⁴

Supplement Safety Note

Supplements receive minimal FDA regulation and may not be safe for everyone. They can interact with medications and other supplements. Always consult your doctor before starting any supplement regimen.

Types of NAD Precursors

NAD+ itself is too large to enter cells efficiently when taken orally. Instead, supplements use precursor molecules that your body converts into NAD+.

Nicotinamide Mononucleotide (NMN)

What is it? NMN is a direct precursor that’s just one step away from becoming NAD+. It’s found naturally in very small amounts in foods like broccoli, avocado, and edamame.

What does research say? Research shows NMN supplements safely improve physical performance, muscle function, and metabolic health, particularly in middle-aged and older adults.⁵

Is it effective? Several human trials show that taking NMN significantly boosts blood NAD levels in healthy adults over 4-12 weeks compared to placebo.⁶

Any downsides? Supplements tend to be more expensive. Despite strong safety data, most comes from small, short-duration studies.

Nicotinamide Riboside (NR)

What is it? NR is a form of vitamin B3 that efficiently converts to NMN and then to NAD+. It bypasses a rate-limiting enzyme called NAMPT that can slow down NAD+ production.

What does research say? Clinical trials show thatNR supplementation is safe and may offer benefits for inflammation⁷, body composition, and possibly neuroprotection.⁸

Is it effective? Multiple human trials show that oral NR supplements significantly raise NAD concentrations in blood and tissues.⁹

Any downsides? NR may be slightly less potent than NMN as a precursor to NAD that is one step further.

Nicotinamide (NAM)

What is it? Also called niacinamide, NAM is the most common form of vitamin B3 in both diet and supplements. It’s found in foods like fish, poultry, eggs, grains, meat, milk, and green vegetables.

What does research say? Clinical studies show nicotinamide helps prevent skin cancer¹⁰, improves skin health, and reduces risk of heart failure.¹¹

Is it effective? Evidence suggests NAM can increase NAD levels, but its effectiveness may vary by tissue type and context.¹²

Any downsides? NAM is generally considered less effective than NMN and NR. It may also come with more side effects in some people.

Niacin (Nicotinic Acid, NA)

What is it? Niacin is the original form of vitamin B3 that can be converted to NAD+ through the “salvage pathway.” It’s the most affordable NAD+ precursor and has been used medically for decades to manage cholesterol.

What does research say? Research shows niacin has well-documented benefits for improving cholesterol profiles by increasing HDL (“good” cholesterol) and lowering LDL (“bad” cholesterol).¹³

Is it effective? High-dose niacin has been shown to increase NAD levels up to 8-fold, which raises questions about optimal dosing for balanced cellular health.¹⁴

Any downsides? Niacin often causes an uncomfortable “flush” effect (temporary skin redness, warmth, and itching) and some users experience stomach issues.

Tryptophan

What is it? Tryptophan is an essential amino acid found in protein-rich foods that can be converted to NAD+ through a lengthy process known as the “de novo pathway.”

What does research say? Studies indicate it may support mood regulation, sleep quality, and neurotransmitter balance due to its role in serotonin production.

Is it effective? As an NAD+ precursor, tryptophan requires multiple conversion steps and is less efficient than direct precursors like NMN.

Any downsides? The conversion rate from tryptophan to NAD+ is relatively low, requiring larger amounts to achieve meaningful NAD+ increases.

Comparison of NAD Precursors

Precursor	What is it?	Effectiveness	Downsides
NMN	Direct NAD+ precursor found in small amounts in vegetables	Significantly boosts NAD+ levels in clinical trials	Most expensive option
NR	B3 form that bypasses rate-limiting enzyme	Well-proven to raise NAD+ in blood and tissues	Slightly less potent than NMN
NAM	Common B3 form in everyday foods	Variable effectiveness by tissue type	Less effective, possible side effects
Niacin	Original B3 form, most affordable	Can increase NAD+ up to 8-fold	Causes “flush” effect, GI discomfort
Tryptophan	Essential amino acid in protein foods	Inefficient, requires multiple conversion steps	Very low conversion rate to NAD+

Forms of NAD Supplements

The effectiveness of your NAD+ supplement might depend on how well it’s absorbed and taken up by your cells.

Standard Oral Capsules/Tablets/Powders

Research consistently shows oral supplements are most reliable, with clinical studies preferring them for their consistent dosing, proven NAD+ elevation, and easy integration into daily routines.

Sublingual Delivery

Tablets or drops placed under the tongue claim to bypass digestion, but minimal independent research confirms superior bioavailability compared to quality oral supplements.

Liposomal Formulations

These encase precursors in microscopic lipid bubbles that protect them from digestive enzymes and potentially enhance cellular uptake. Manufacturer data suggests better bioavailability, but independent research is limited.

Other Forms

Nasal sprays provide rapid delivery through the nasal mucosa
Transdermal patches deliver precursors through the skin
IV administration delivers NAD+ directly into the bloodstream (clinical settings only)

While advanced delivery systems offer potential advantages, standard oral formulations still have the most extensive clinical research supporting their effectiveness.

Delivery Method	Effectiveness	Research Support
Oral Capsules/Tablets/Powders	Reliable cellular uptake with consistent dosing	Extensive clinical research support
Sublingual Delivery	Claims improved absorption by bypassing digestion	Limited independent verification
Liposomal Formulations	Enhanced protection from digestive enzymes	Mostly manufacturer data, limited independent studies
Nasal Sprays	Rapid delivery through nasal mucosa	Minimal clinical research
Transdermal Patches	Gradual delivery through skin	Few published studies
IV Administration	Direct bloodstream delivery (clinical settings only)	Used in specific therapeutic contexts

Dosages: How Much Should You Take?

Finding the right NAD+ precursor dosage means balancing research with your personal needs.

For NR, studies typically use 300-1000 mg daily. Higher doses (1000+ mg) may keep NAD+ levels elevated longer and are sometimes used for specific health conditions.

Research has tested daily NMN doses between 250-1200 mg. Some evidence suggests the higher end of this range (600-1200 mg) may work better for things like aerobic capacity.

Start low (250-500 mg daily of either NR or NMN) to check how your body responds before trying higher amounts.

For specific health concerns, talk to a healthcare professional who can guide you based on your health and goals.

Precursor	Typical NAD-Boosting Dosage
NMN	250-1000 mg/day
NR	300-1000 mg/day
NAM (Niacinamide)	100-500 mg/day
Niacin	15-50 mg/day
Tryptophan	1000+ mg from dietary sources

Side Effects and Safety

NAD+ precursors have shown good safety records in human studies at common doses.

NR has been tested at up to 2000 mg daily for several months, with a recent study using even 3000 mg daily for 4 weeks in Parkinson’s patients without serious side effects.

Can NAD+ Supplementation Improve Your Sleep Quality?

Written by Jinfiniti Science on January 20, 2025. Posted in NAD+, NAD, NAD+ Precursors, Nicotinamide, Sleep. No Comments on Can NAD+ Supplementation Improve Your Sleep Quality?

Getting a good night’s sleep shouldn’t feel like chasing an impossible dream. Yet for many people, quality sleep remains frustratingly elusive, despite following all the standard advice about blue light, bedtime routines, and bedroom temperature.

The solution might lie not in your bedroom, but in your cells.

Among the many molecules involved in sleep regulation is NAD+ (Nicotinamide Adenine Dinucleotide), which plays an important role in your body’s circadian rhythms – the internal clock that helps regulate sleep and wake cycles. This molecule works alongside other important factors like hormones and neurotransmitters to influence sleep patterns.

Let’s explore what science tells us about the role of NAD+ in sleep quality and whether boosting NAD+ levels could help you get better rest.

Key Takeaways:

NAD+ plays a fundamental role in regulating your body’s circadian rhythms and sleep-wake cycles, with research showing its levels directly impact sleep quality and duration
Scientific studies have demonstrated that maintaining optimal NAD+ levels can improve sleep efficiency and may even reduce the amount of sleep needed to feel restored
Your body’s NAD+ levels naturally decline with age, but can be boosted through physical activity, diet, and targeted supplementation to support better sleep patterns

What is NAD+?

NAD+ is a coenzyme involved in hundreds of biological processes, including the regulation of circadian rhythms and mitochondrial function that directly influence sleep-wake cycles, making it a fundamental molecule for maintaining healthy sleep patterns and cellular repair during rest¹. Researchers are actively exploring NAD+’s potential benefits across multiple areas where declining levels impact aging including sleep quality, athletic performance, and skin health.

Does NAD+ Improve Sleep Quality? A Look at the Evidence

Wonder why some nights you sleep better than others? Beyond the usual suspects like late-night coffee or racing thoughts, your cellular NAD+ levels help regulate your sleep quality at the molecular level.

Here’s an overview of the latest research on how your body’s NAD+ status can shape your nightly rest.

Circadian Rhythm Regulation

Your body isn’t just randomly waking up and going to sleep. It runs on an exquisitely precise internal clock. This biological timekeeper is known as your circadian rhythm and tells your body when it’s time to be awake and when it’s time to start winding down.

Research in Molecular Cell has shown that NAD+ controls circadian reprogramming and decreases in total NAD levels are associated with circadian and sleep–wake disruptions². This drop directly impacts quality of sleep, often leaving you feeling unrested, even when following a normal sleep schedule.

Sleep-Wake Metabolism

Your brain doesn’t just power down when you sleep – it actually shifts into a different kind of energy mode. During deep sleep, your brain uses about half as much glucose as it does when you’re awake. This major metabolic shift involves NAD+, which helps convert nutrients into energy your cells can use.

During your waking hours, your brain accumulates some natural wear and tear from all its activity. When you sleep, NAD+ helps coordinate the complex chemistry that cleans up this cellular stress.

A recent study found that supplementation with NAD+ precursor nicotinamide riboside resulted in subjects requiring less sleep to get the same restorative benefits – about 17% less deep sleep, to be exact³. This would be equivalent to reducing human sleep from 8 to 6.6 hours.

Sleep Duration and Efficiency

Recent research suggests that NAD+ and its reduced form NADH play important roles in sleep regulation, particularly in people with chronic fatigue syndrome (ME/CFS). When ME/CFS patients were given a combination of NADH and CoQ10 daily, researchers observed several improvements in sleep-related measures⁴:

Sleep duration showed significant improvement at 4 weeks into treatment

Habitual sleep efficiency improved at 8 weeks

These improvements were observed within the treatment group, suggesting the supplements may help optimize sleep patterns

Apigenin and NAD+ Levels

Apigenin is a flavonoid found abundantly in parsley and chamomile and known for its ability to enhance sleep quality. Research has demonstrated that apigenin acts as an inhibitor of CD38, an enzyme that continuously breaks down NAD+ in the body⁵.

Through this protective mechanism of CD38 inhibition and NAD+ preservation, apigenin has been shown to improve multiple aspects of sleep, including reducing time to fall asleep and increasing the duration of deep, restorative sleep phases⁶.

Quality of Sleep in Parkinson’s Disease

Sleep disturbances are a hallmark of neurodegenerative diseases like Parkinson’s, where disrupted NAD+ metabolism plays a significant role. Research suggests that cellular energy deficits in these conditions correlate with declining NAD+ levels, which can further impact sleep quality.

One study examining niacin supplementation reported modest but meaningful improvements in sleep patterns – including a 10% reduction in nighttime awakenings⁷. While not dramatic, maintaining stable sleep patterns in progressive neurological conditions represents an important outcome.

Reduced Daytime Sleepiness

Research has shown that NMN (nicotinamide mononucleotide) reduces afternoon drowsiness in older adults by converting directly into NAD+ in your cells, helping maintain healthy sleep-wake patterns without disrupting nighttime rest⁸.

This suggests that taking NMN strategically in the afternoon can help reset your daily rhythm—eliminating post-lunch fatigue while preparing your body for deeper, more restorative sleep at night.

How to Improve NAD+ Levels for Healthier Sleep

NAD+ levels decline dramatically as you age, dropping by about 50% between your 20s and 80s. This reduction directly impacts your sleep cycles and cellular repair processes.

When NAD+ levels fall, you spend less time in deep sleep phases. These stages are where your body conducts essential maintenance: repairing cells, restoring energy, and regulating vital functions. Without sufficient deep sleep, fatigue and reduced resilience become daily challenges.

The great news? Scientific research confirms that optimizing your NAD+ levels can provide relief from common sleep issues. When your NAD+ levels are balanced, your body is better equipped to enter the deep, restorative sleep phases essential for repair, recovery, and overall rejuvenation.

Three primary strategies can help maintain and boost your NAD+ levels:

Physical Activity: Regular exercise naturally stimulates NAD+ production in your cells. Research shows that consistent physical activity helps maintain NAD+ at levels typically seen in younger adults, supporting both sleep quality and cellular energy production⁹.

Diet and Nutrition: Several foods naturally support NAD+ levels through precursor molecules. Wild-caught fish, mushrooms, and leafy greens provide building blocks for NAD+ synthesis. However, dietary sources alone rarely provide sufficient NAD+ precursors to counter age-related decline.

Targeted Supplementation: Direct supplementation with NAD+ precursors provides the most efficient way to boost cellular NAD+ levels. Modern supplement formulations can deliver precise dosages of compounds that your body converts directly into NAD+.

Vitality ↑® NAD+ Booster offers a comprehensive approach to NAD+ optimization. Our clinically-validated NAD powder formulation combines precursors NMN and niacinamide with synergistic ingredients D-ribose and creatine monohydrate. This precise combination supports both NAD+ production and cellular energy systems.

With consistent NAD+ supplementation at the right dosage, you can increase NAD levels and create a positive cycle where better sleep supports cellular repair, and optimized cellular function promotes higher quality rest.

Frequently Asked Questions

Can NAD+ Help for Insomnia?

NAD+ directly influences your sleep-wake cycles at the molecular level, making it particularly relevant for sleep quality and insomnia. The coenzyme regulates your internal clock while powering the cellular processes that enable deep, restorative sleep.

Science shows that optimal NAD+ levels support sleep cycle regulation, cellular energy production during rest, nighttime repair processes, and stress response systems. These benefits become more important with age, as NAD+ levels naturally decline. Testing and maintaining proper NAD+ levels through targeted supplementation can help restore natural sleep patterns, especially for those experiencing age-related insomnia.

Does NAD Make You Sleepy?

NAD+ doesn’t induce drowsiness. Instead, it optimizes your body’s natural energy cycles. NAD+ actually does the opposite of making you sleepy – it can help improve sleep quality and reduce fatigue while potentially decreasing overall sleep time.

Should NAD+ Be Taken in the Morning or at Night?

Most people benefit from taking NAD+ supplements in the morning to support daytime energy production. Some research suggests afternoon supplementation can help reduce evening fatigue while supporting nighttime sleep quality. The key is consistency—regular supplementation maintains steady NAD+ levels for optimal results.

How Long Does it Take NAD+ to Start Working?

While individual responses vary, many people notice improvements in energy levels within the first few weeks of consistent NAD+ supplementation. The full spectrum of benefits, including improvements in poor sleep quality and cellular repair—typically develop over continued use as your body’s NAD+ levels stabilize at optimal ranges.

NAD vs Niacin vs Niacinamide: Vitamin B3 Differences Decoded

Written by Jinfiniti Science on December 21, 2024. Posted in NAD+, NAD+ Precursors, Niacin, Nicotinamide, Vitamin B. No Comments on NAD vs Niacin vs Niacinamide: Vitamin B3 Differences Decoded

The vitamin B3 on your supplement label hides a deeper truth.

What appears as a single nutrient actually represents a family of compounds—each following its own path through your cellular machinery.

Understanding the difference between NAD, niacin, niacinamide, and nicotinamide isn’t just biochemistry—it’s the key to unlocking specific health benefits while avoiding unwanted effects.

Let’s decode what your supplement label doesn’t tell you about the forms of vitamin B3.

Vitamin B3: A Short History

In 1937, Conrad Elvehjem made an accidental discovery that would reshape our understanding of human health. While studying black tongue disease in dogs, he isolated a compound that not only cured the canine condition but also proved to be the key to solving pellagra—a devastating human disease that had claimed thousands of lives across the American South.

That compound was niacin, but it was just the beginning. What started as a single vitamin has evolved into a complex family of molecules. Modern longevity researchers have transformed B3 from a simple nutritional supplement into a cornerstone of aging research, with different forms of the vitamin showing distinct effects on cellular health, energy production, and DNA repair.

Is NAD More Than Just Another B3?

NAD or nicotinamide adenine dinucleotide stands apart from other B3 vitamins—it’s not a form of B3, but rather a critical coenzyme your cells use as currency in energy transactions. We can think of NAD as cellular currency: every metabolic purchase your cells make requires NAD+, from breaking down glucose¹ to repairing damaged DNA².

A single red capsule sits apart from a large pile of various colorful pills and supplements.

But here’s where it gets interesting: despite NAD+’s fundamental role, you can’t simply swallow it as a supplement. The molecule is too large and unstable to survive digestion³. Your body must build its NAD+ supply from smaller B3 building blocks—each with its own efficiency rating in the conversion process.

The connection between NAD+ and aging emerged when scientists discovered that our NAD+ levels plummet as we get older. This decline correlates with many hallmarks of aging: decreased energy production, impaired DNA repair, and reduced cellular resilience. Restoring NAD+ levels has become a central focus in longevity research.

Let’s break down the family of B3 compounds and their relationship to NAD+:

B3 Form	Conversion to NAD+	Key Benefits	Sources
Niacin (Nicotinic Acid)	3-step process, moderate efficiency	Cardiovascular health, cholesterol management	Food sources, immediate-release supplements
Niacinamide (Nicotinamide)	2-step process, good efficiency	Skin health, joint function	Supplements, fortified foods, skincare products
Nicotinamide Riboside (NR)	2-step process, high efficiency	NAD+ boosting, cellular energy	Specialized supplements

What is Niacin? The Original B3

Niacin—known chemically as nicotinic acid—remains the most thoroughly studied form of vitamin B3. Its simple molecular structure belies its power: a six-member ring with a carboxylic acid group that gives this compound its distinctive properties.

You’ll find niacin throughout the natural world. It’s abundant in meat, fish, and nuts, with mushrooms and avocados providing substantial plant-based sources. Unlike other B3 forms, it announces its presence in your body with an unmistakable sensation.

The infamous “niacin flush” stands as both blessing and curse. Within 30 minutes of taking higher doses, your skin turns red and warm—a temporary but often intense experience that feels like a sunburn. This flush isn’t dangerous—it’s actually a sign of niacin expanding your blood vessels, the same mechanism behind its cardiovascular benefits⁴.

Beyond circulation, niacin shows remarkable effects on blood lipids that other B3 forms can’t match. It’s the only B3 variant proven to both lower harmful LDL cholesterol and raise beneficial HDL cholesterol⁵. This unique property has kept niacin relevant in an era of more exotic B3 derivatives.

Niacinamide vs Nicotinamide

The supplement industry’s cleverest marketing trick lies in making two identical molecules seem different. Niacinamide and nicotinamide are perfect chemical twins—same structure, same effects, same molecule.

This dual naming stems from historical quirks in scientific nomenclature. While researchers prefer “nicotinamide,” the cosmetics industry adopted “niacinamide”—creating an illusion of distinction that persists in marketing materials and product labels.

The truth? Both names describe a modified form of B3 where the carboxylic acid group of niacin has been replaced with an amide group. This small change eliminates the flush reaction while opening new therapeutic doors. Your skin cells particularly love this form of B3—they readily absorb it and use it to repair UV damage, reduce inflammation, and regulate oil production⁶.

The benefits extend beyond skincare. Whether labeled niacinamide or nicotinamide, this form of B3 supports joint health, aids cellular repair, and helps maintain DNA integrity—all without the circulation-related effects of standard niacin.

Nicotinamide Riboside and Nicotinamide Mononucleotide

A common misconception clouds the NAD+ precursor landscape: while Nicotinamide Riboside (NR) belongs to the B3 family, Nicotinamide Mononucleotide (NMN) does not. NMN represents the next step in the NAD+ production pathway—a larger, more complex molecule that sits between B3 vitamins and NAD+ itself.

When comparing NMN and NR, both compounds share a singular purpose: boosting NAD+ levels. But they take different routes to this destination. NR enters cells directly through specialized transporters, while NMN must either convert to NR before absorption or use recently discovered transport mechanisms. This distinction has sparked intense debate in the research community about their relative effectiveness.

The scientific evidence paints a nuanced picture. Clinical trials show both molecules can increase NAD+ levels, with participants reporting improved energy, better sleep quality, and enhanced exercise performance. Studies on safety and side effects for both compounds are encouraging—NR has demonstrated a strong safety profile across multiple long-term trials⁷, while NMN has shown excellent tolerability in human studies⁸, with research continuing to expand our understanding of both molecules.

Recent research has uncovered tissue-specific preferences for these molecules⁹. Some organs appear to utilize NR more efficiently, while others show stronger responses to NMN. This finding suggests that the “best” NAD+ precursor might depend on your specific health goals and target tissues.

Choosing a B3 Supplement

Woman's perspective, hands holding a glass of water with a B3 supplement

Selecting the right B3 supplement demands a strategic approach based on your health objectives and biochemical needs. The form you choose defines not just the benefits you’ll receive, but also how your body will respond to the supplement.

Your supplementation strategy should align with specific health goals:

For cardiovascular health and lipid management: Standard niacin remains the gold standard, though the flush reaction requires careful dose titration. Start with 100mg and gradually increase to assess tolerance.
For skin health and inflammation: Choose products containing niacinamide (nicotinamide), particularly in concentrations between 2-10% for topical applications. Look for formulations free of potential irritants.
For cellular energy and longevity support: NAD+ precursors offer the most direct path. Modern research points to combination approaches that support multiple aspects of cellular energy production.

When evaluating NAD+ precursor supplements, look beyond basic formulations. The most effective products combine precursors with synergistic compounds that support cellular energy metabolism—a strategy backed by emerging research.

The Vitality ↑® NAD+ Booster exemplifies this advanced approach. Combining NAD precursors NMN and nicotinamide with cellular energy enhancers Creatine monohydrate and D-Ribose, our NAD precursor powder supports both NAD production and overall energy metabolism. This clinically-validated formulation addresses the complex nature of cellular energy production.

Before starting any B3 supplementation:

Consult healthcare providers if you take medications, particularly diabetes drugs or statins
Choose morning supplementation for most forms, except when using niacin (which some prefer at night to sleep through the flush)
Store your supplements in cool, dry places—NAD precursors particularly benefit from proper storage
Look for third-party testing certification and clear ingredient labeling
Consider cost per effective dose rather than just price per bottle

The right B3 supplement can transform your cellular health—but only when chosen with purpose and used with understanding. Your investment in B3 supplementation should match your health goals, backed by science and quality manufacturing.

“I felt like my brain was broken. I was so tired. I battled high levels of anxiety, having panic attacks three times a week, I felt fatigued all the time and needed 400 mg of caffeine and 2 naps per day just to function. It felt like a single setback could slide me off the cliff.

Initially, I did a big round of NAD IV, which was $4000, but I was desperate. It gave me a lot of energy and mental lift, but it wasn’t sustainable. A few months later, I was feeling the same. And then I discovered Jinfiniti. My NAD levels were sorely deficient.

Within several months of taking the Vitality ↑® NAD+ Booster, my energy is much higher, my mental health and anxiety is so much better, and I’ve even lost some of the unwanted stubborn weight that wouldn’t go away. And my NAD levels are now optimal at 55.4 thanks to Vitality ↑® NAD+ Booster.

My husband and I feel we have our lives back and I know Jinfinti’s been a huge part of that.”

—Sarah W., one of our monthly subscribers of Vitality ↑® NAD+ Booster.

Mental Clarity, Postpartum, Recovery

“After Dante was born, I still regularly experienced higher than normal levels of fatigue (like my cells were tired). I didn’t wake up as energized as I used to and my recovery wasn’t as good after a workout. I had some lingering brain fog and lack of mental clarity. Metabolism seemed to be lower.

After two weeks of taking Vitality ↑® NAD+ Booster, my brain fog has lifted, my metabolism is coming back and I’ve even felt some of that postpartum baby fat shedding faster. I feel better, happier, and more alert when I wake up. I am bouncing back faster and better from workouts. I am back to myself, which feels amazing.”

—Dr. Jennifer Fraboni (Doc Jen)

Severe Fatigue

“Over the last year, I started experiencing really debilitating fatigue in the afternoon. About six months ago, I did the NAD test and got shockingly low results coming in deficient. I’m perfectly healthy. I don’t have any diagnosed medical conditions. I exercise regularly, I eat well, and I’m not overweight.

I was so appalled and determined to start taking the supplements regularly.

Two weeks into taking the NAD supplement, the fatigue disappeared. I was absolutely astonished. I’m not going to stop taking the supplements to see if the fatigue comes back. I’d recommend the Vitality ↑® NAD+ Booster to anyone who needs extra energy.”

—Dr. James Goodwin, Director of Brain Health Network, London, UK.

Movement

“I have been using the supplement for the last 2 months. During this time I have increased my movement and feel strong and energized over the whole day. I’m a full time working mum and love all kinds of exercise. The best thing is the even energy all day so I can train/exercise/move whenever.”

—Louise N.

Overall Vitality

When my friend gifted me Vitality ↑® NAD+ Booster I was skeptical however this skepticism has turned into gratitude for Jinfiniti. Vitality ↑® NAD+ Booster has exceeded my expectations as a comprehensive wellness supplement. The promised benefits of increased energy, enhanced performance, improved sleep quality, and reduced inflammation have been noticeable in my daily life.

I’ve experienced a significant reduction in muscle and joint pains, and the positive impact on allergic and asthmatic symptoms is truly remarkable. The supplement’s influence on mental clarity and dementia symptoms adds an extra layer of appeal. The promise of improved health functions, including the liver, kidney, heart, and thyroid, provides a sense of overall well-being. Vitality ↑® NAD+ Booster lives up to its claims, making it a valuable addition to my wellness routine.”

4 Ways to Have a Fantastic, Energy-Rich 2024

Written by Jinfiniti Science on January 11, 2024. Posted in NAD+, Energy and Fatigue, NAD+ Precursors, Nicotinamide.

Who wants to have a fantastic 2024 with energy to spare? Who wants to feel energized and empowered without reaching for a second cup of coffee during your afternoon lull—or maybe without reaching for a first?

If you’re anything like me, much of the quality of your year depends on your energy levels. If your energy levels are low, it’s hard to have a productive year, but if you feel amazing and your energy levels are soaring, it’s hard not to have an incredible year.

So today I want to focus on some simple—but attainable—steps to having a great cellular-energy year.

Here’s one of my favorite stories from a recent customer who submitted a review on our site:

“Within two weeks of taking Accuri I noticed my energy levels increasing. Additionally, I have always been a walker, but this past summer I was often fatigued after 3 or 4 miles. After taking Accuri for a month or so, I’d walk 10-15 miles without fatigue.”

–Dawn

Regarding testimonials, we’re giving away 1 free bottle of Vitality ↑® NAD+ Booster to our favorite review every week for the next several weeks!

But back to the steps for your best cellular-energy year yet. Let’s begin:

1. Eat energy rich foods and avoid energy depleting foods.

Energy-rich foods are the powerhouse fuel that our bodies crave to keep us going throughout the day. These foods are packed with macronutrients like complex carbohydrates, healthy fats and clean proteins. So, whether you’re reaching for a handful of nuts, a bowl of roasted purple sweet potatoes, a piece of salmon or a delicious avocado, choose energy-rich foods that fuel your body with the power it needs to meet the demands of the day.

And while eating all of these good foods, make sure you are avoiding foods that kill your energy, foods such as: processed foods, refined sugars, excessive caffeine, and alcohol. Eating any of these things regularly is a sure way to feel like a tired zombie in 2024.

2. Take energy enhancing supplements like Vitamin Bs and creatine.

Vitamin B and creatine are a dynamic duo when it comes to boosting your physical energy. The B-vitamins—especially B12 and B6, play a pivotal role in converting the food we eat into usable energy. They assist in the production of red blood cells, which transport oxygen to muscles, enhancing overall stamina.

Creatine, for its part, is like a power-up button for your muscles. It helps generate ATP, the primary energy currency in cells, allowing for quick bursts of energy during intense physical activities.

Together, these two work in synergy to optimize energy production at the cellular level.

3. Exercise 3-4 times per week.

Did you know that exercise is the only thing that causes our mitochondria to reproduce on its own?

Exercising 3-4 times a week can be a game-changer when it comes to boosting your physical energy levels. Regular physical activity is like a shot of adrenaline for your entire system. Not only does it improve cardiovascular health, enhancing blood flow and oxygen delivery, but it also stimulates the release of endorphins—those feel-good hormones that act as natural energy boosters.

Regular exercise promotes better sleep quality, allowing your body to recharge and rejuvenate, which becomes a positive cycle—the more you move, the more energy you have, and the better you sleep, and the more energy you have to move again!

4. Take Vitality ↑® NAD+ Booster

NAD is the body’s most important powerhouse when it comes to influencing its energy levels. It is a key player in cellular respiration, the process that converts nutrients into energy. NAD is linked closely to mitochondrial health, the energy producing hubs within our cells. But as we age, of course, NAD levels tend to decline, which impacts overall energy metabolism, and thus—our overall physical energy.

If you want peak energy in 2024, we recommend starting an NAD supplement.

And as far as NAD supplements go, look no further than our Vitality Blend, the best NAD optimization product in the world. It optimizes—not just improves—intracellular NAD for 90% of people alone, which no other NAD supplement can come close to promising.

While other brands increase NAD levels by 20-40% at best, we often see levels increase by 200-300% like we did with Doc Jen, a prominent doctor of physical therapy who loves the Vitality ↑® NAD+ Booster. We even back it with a 60-day Money Back and Efficacy Guarantee. And that’s because we back up the Vitality ↑® NAD+ Booster with real testing, where all of the proof lies!

Some bonus suggestions for the most energy-rich 2024 yet?

Protect your energy like it’s your job.
Get outside.
Pay attention to your cellular energy like your quality of life depends on it (here’s a hint: it does)
Test your NAD levels. There’s nothing better and more accurate for knowing where your cellular energy is currently at and where it can go.

Remember, an energy-rich year is a great year.

What Does Peak Performance Aging Look Like? Is Cognitive Aging Really a Fact of Life?

Written by Jinfiniti Science on December 8, 2023. Posted in NAD+, Inflammation, NAD+ Precursors, Neurological Diseases, Nicotinamide.

Peak performance aging is a radical concept that throws a pie in the face of traditional aging. The traditional theory of aging is that there is little that we can do to stop the slide.

We’ve all heard accepted-aging statements: “Well, there’s nothing you can do about it. I guess we’re just getting old.” “Can’t teach an old dog new tricks.” “Aches and pains are all part of getting old.” “Aging comes for us all.”

One leading thinker, Steven Kotler, a noted expert in the field of peak performance begs to differ.

“Aging is a fact of life, but old is all a mindset.”

A NY Times bestselling author, journalist and flow researcher, Kotler explains further about the myth of uncontrollable aging in his research and his recent book, Gnar Country: Growing Old, Staying Rad.

“Ageism is the most socially acceptable stereotype¹ in the world,” he said. “But it has radical consequences.” He further explains, aging is a mindset,”A proper mindset towards aging is also a growth mindset. If you have a fixed mindset around aging, everything about lifelong learning is going to be worthless.”

When psychologist Mihaly Cskiszentmihalyi coined the term Flow in the 70s to explain the peak performance zone he discovered people could tap into, he discovered a unique psychological state like any other and inadvertently helped catalyze the positive psychology movement.

When it comes to aging, the latest research indicates that not only is regularly activating flow state a key factor in long-term life satisfaction, it is also neuro-protective against cognitive decline (see George Valliant’s research at Harvard-citations will be on our blog).

You may be wondering what all this may have to do with Jinfiniti, and we’ll get to that in a second.

But first, here are a few things that happen when your body is in Flow State:

All six positive neurochemical cocktails are released.
Life satisfaction goes up.
Cognitive decline slows and even reverses.

The long slow route theory of aging states that skills decline as you age, therefore cognitive decline is inevitable. But new research that supports peak performance aging flys in the face of that with practical guidance on how to achieve peak performance aging.

To avoid cognitive decline, the research says that you need to:

Solve the crisis of identity by the time you’re 30.
Have match/fit quality by the time you’re in your 40s.
In your 50s, you need to combat two things:
1. Risk aversion. If you are risk averse, you are fearful which releases norephedrine, which then blocks . You need challenging, creative social experiences and should remain open, curious and explorative.
2. Physical fragility. According to Kotler, you do this through “challenging social activities that involve deliberate dynamic play in novel outdoor environments.” To protect against cognitive decline, you need neurogenesis, the birth of new neurons. You have 700 new neurons being made daily, with the majority of them being made in the hippocampus.

So why is this important? In the hippocampus, your brain remembers novel outdoor experience as that is what your brain has been trained to do for thousands of years.

What does a positive, even a growth mindset around aging look like?

Six neurochemical cocktails released in flow:

1. DOPAMINE

Drives desire, excitement, enthusiasm, sexual desire, curiosity, to test your limits

2. NOREPINEPHRINE

Brain’s version of adrenaline. Produces a huge increase in energy and alertness. When you’re obsessed with an idea, can’t stop thinking about the person you just met, then it’s activated

3. OXYTOCIN

Produces love, trust, friendship. It’s pro social. Underpins everything from long term bliss to cooperative businesses and relationships.

4. SEROTONIN

Calming, peaceful. Gives a mood lift. Shows up post meal with the desire to take a nap. Important for satisfaction and contentment

5 & 6. ENDORPHINS & ANANDAMIDE

Heavy duty stress & pain relievers. Replaces the weight of the day with euphoric happiness.

Kotler identifies five categories of functional fitness that need to be trained² and maintained: strength, stamina, agility, balance and flexibility.

“These are all use it or lose it skills, if we want to retain our physical abilities late in life³,” he said.

He noted a study about aging conducted by Yale professor Becca Levy⁴ that proved there was a significant correlation in how people thought about aging and viewed themselves when exposed to negative stereotypes.

“This could be people saying, ‘You’re too old for this s- -t,’ or you telling yourself ‘You’re too old for this s- -t,’” he explained. “By the time they were 60, we see a 30% greater memory decline in people who have been exposed to negative stereotypes around aging. Literally, we’re killing each other with these ideas.”

So here’s how peak performance aging ties into what we’re about at Jinfiniti:

If you are suffering in one of the vital biomarkers that can precipitate and accelerate aging, then it dramatically diminishes your potential longevity and healthspan.

Just this week, I met a 35-year-old with significant health issues whom we may be able to help pre-empt by testing and more precisely diagnosing while also optimizing NAD levels, so it can happen at almost any age.

NAD deficiency affects your energy, which in turn, affects your drive and motivation to engage in peak-performance, anti-aging related activities. The sooner you start ensuring your NAD is optimized, the sooner you throttle back aging, thereby extending your healthspan immediately.

If you happen to be 50+ years old, your NAD levels are likely not optimal unless you’ve been taking our Vitality ↑® NAD+ Booster for quite some time. According to extensive research, the average healthy 50-year-old has already lost 50% of their NAD levels.

SHOP NAD+ BOOSTER

Here at Jinfiniti, our flagship NAD supplement, the Accuri® Vitality ↑® NAD+ Booster, is a patent-pending formulation that has been extensively tested in clinical studies by hundreds of clinics and by thousands of consumers. It allows optimization of NAD in approximately 90% of users, a figure incomparable to any other NAD supplementation on the market.

No other molecule comes close to helping your cells function optimally as much as NAD.

This means that pain, inflammation, fatigue, brain function (obstacles to Flow State & peak performance aging) all decrease while mental clarity, stamina, recovery, energy, and youthfulness (ingredients of Flow State) all increase when NAD is optimized.

Hence why NAD optimization plays an inextricable link in achieving peak performance aging at the molecular level.

Whether you’re a pro athlete or you’re working in the corporate world, building a business, or raising a family, taking care of your cellular vitality is paramount to how you feel, how you perform but also how and whether or not you age.

That’s why NAD is arguably the foundational molecule for all of life. Plus, if you are over 40 years old your NAD levels are essentially guaranteed to be deficient. So get one of our NAD tests and a bottle of Vitality ↑® NAD+ Booster to tune up your NAD levels. Better, yet, our NAD starter kit is a terrific value as it’s 2 tests and 2 Vitality ↑® NAD+ Boosters, so within two months we can verify that your NAD levels are up to optimal levels.
