What are NAD Boosters and Do They Really Work?

The quest for staying young has fascinated humans for centuries. While we haven’t found the fountain of youth, scientists have discovered something intriguing: NAD+, short for nicotinamide adenine dinucleotide, a molecule that plays an all-important role in how we age.

As our NAD levels naturally decline over time, researchers are exploring whether molecules and therapies that boost NAD+ levels could help slow down the aging process. But can these NAD boosters—ranging from supplements like nicotinamide riboside (NR) and nicotinamide mononucleotide (NMN) to therapies like NAD IV infusions—actually turn back the clock, or are they just another anti-aging promise?

Key Takeaways:

• NAD boosters are compounds that increase cellular NAD+ levels, including NAD+ precursors (like nicotinamide riboside and nicotinamide mononucleotide) and enzyme modulators. These supplements aim to counter the natural decline of NAD+ that occurs with age and have shown promising results in clinical trials.
• Scientific research supports the safety and efficacy of NAD+ boosters, with benefits ranging from improved cardiovascular function and metabolic health to enhanced cognitive performance and reduced inflammation.
• While NAD+ boosters can benefit adults of all ages, they may be particularly valuable for those over 40 who experience natural age-related NAD+ decline. The best results come from choosing high-quality, third-party tested supplements and combining them with healthy lifestyle practices.

What Are NAD Boosters?

NAD boosters are compounds that increase the cellular level of NAD+, a crucial cofactor in energy metabolism, DNA repair, and cellular signaling¹. They include NAD+ precursors (such as nicotinamide riboside or nicotinamide mononucleotide) and modulators of NAD-consuming or NAD-producing enzymes. NAD boosters have attracted attention due to their potential to counteract the decline in NAD+ levels that can occur with aging and, in turn, help maintain healthy metabolic function, support DNA repair, and regulate other vital bodily processes.

While NAD-boosting molecules show promising potential, individuals can also naturally increase their NAD+ levels through lifestyle approaches like diet, regular exercise, intermittent fasting, limiting alcohol consumption, and eating protein-rich foods. However, for those seeking a more direct approach, NAD+ precursors provide a targeted method to support cellular health and potentially mitigate age-related decline.

Do NAD+ Boosters Really Work?

You may have heard a lot of buzz about NAD+ boosters and their potential to support healthy aging and improve cellular function. But do they really work? The research so far is promising. 

Numerous studies have shown that various NAD precursor compounds (colloquially referred to as NAD boosters) effectively increase NAD+ levels in human subjects.

For example, a well-designed, randomized, double-blind, placebo-controlled trial demonstrated that regular supplementation with nicotinamide riboside significantly increased NAD+ levels in healthy middle-aged and older adults². The benefits were impressive, too, including reduced blood pressure and improved arterial flexibility.

Another study that combined NR with pterostilbene (NRPT) reported a 40% increase in NAD+ levels after just four weeks, with sustained improvements over eight weeks³. These findings suggest that certain NAD boosters can be a safe and effective way to enhance NAD+ metabolism and potentially deliver health benefits that combat aging.

However, the reality is that not everyone will experience the same results. Individual responses to NAD boosters can vary widely. Factors such as your baseline NAD+ levels, age, gender, genetics, and overall health play significant roles in how well these interventions work for you. 

For example, some studies have reported modest increases in NAD+ levels of 40-59% with lower doses of NR or NMN, while others have observed more substantial increases—up to 5.7-fold—with higher doses⁴. Ultimately, it comes down to how your body metabolizes these compounds.

What works for your friend or family member might not work as well for you, and finding the right dosage or formulation can take some trial and error. Moreover, various therapeutic approaches, such as NAD supplementation or IV therapy, will tend to yield distinct outcomes.

Since everyone’s health needs differ, it’s always recommended to consult with your healthcare provider regarding the appropriateness of any new intervention or supplementation regime for your specific situation.

Potential Benefits of NAD Boosters

When your body maintains optimal levels, the benefits of NAD can touch virtually every aspect of your health and well-being, from energy production to DNA repair. Here’s how optimizing your NAD+ levels may help support your body:

• Supporting heart health and circulation: NAD+ promotes cardiovascular function and healthy blood flow⁵.
• Enhancing metabolic function: NAD+ aids in efficient energy metabolism⁶ and blood sugar regulation.
• Boosting brain health and cognitive function: NAD+ improves mental clarity, memory, and overall brain performance⁷.
• Increasing muscle strength and athletic endurance: NAD+ enhances physical performance⁸ and muscle recovery.
• Reducing chronic inflammation: NAD+ helps lower inflammation⁹, supporting a healthier immune response.
• Improving sleep and rest quality: NAD+ encourages better sleep patterns¹⁰ and more restorative rest.
• Alleviating symptoms of anxiety and depression: NAD+ may help regulate mood and reduce feelings of stress and anxiety¹¹.
• Supporting cellular energy production: NAD increases ATP production¹², combating fatigue and boosting daily energy.
• Promoting skin repair and slowing aging: Supports skin regeneration and reduces visible signs of aging¹³.

Many people notice these improvements within weeks of starting NAD boosters, though individual results may vary. The key is consistency – giving your body the regular support it needs to maintain optimal NAD+ levels and function at its best.

Are NAD Boosters Safe?

NAD precursors are known for their strong safety profile. In fact, most people tolerate them well when taken as recommended¹⁴. However, like any supplement or medication, NAD boosters can come with potential side effects, particularly if misused or taken in excessive amounts.

Generally, side effects from NAD boosters are rare and mild. If they do occur, they may include temporary stomach discomfort, mild headaches when first starting, fluctuations in energy levels, or occasional changes in sleep patterns. These effects typically improve as the body adjusts to the supplement.

If you’re considering NAD IV therapy, it’s essential to have the procedure performed by a skilled healthcare professional to reduce the risk of complications, such as infection, vein irritation, and other possible side effects of NAD IV therapy.

Moreover, if you are pregnant, nursing, have underlying health conditions, take prescription medications, or have autoimmune disorders, it’s important to consult your doctor before using supplements like NAD boosters, as these supplements could cause side effects or interact with your medications.

To get the most from NAD boosters while minimizing risks, choose high-quality products from reputable brands, begin with the recommended dosage, and pay attention to how your body responds. Always communicate with your healthcare provider and schedule regular check-ups to monitor your progress.

Ultimately, while NAD boosters are safe and can support healthy aging and cellular function for most individuals, they are most effective when combined with a balanced lifestyle, including proper nutrition, regular exercise, and quality sleep.

Who Should Consider Taking NAD Boosters?

While NAD+ levels are generally higher in younger populations, everyone can potentially benefit from supporting their NAD+ balance, depending on lifestyle, health needs, and age-related decline.

For younger individuals, NAD+ levels are typically sufficient to support metabolic and cellular functions, making supplementation less necessary. However, children and young adults experiencing high stress, engaging in intense physical activities, or recovering from health issues may still benefit from maintaining balanced NAD levels.

For adults, especially those in their 40s and older, the natural decline in NAD+ becomes more pronounced, often leading to reduced energy, a slower metabolism, and cognitive changes. At this stage, NAD boosters can help counteract age-related declines, enhance energy levels, and support overall cellular health.

Individuals experiencing symptoms of NAD deficiency, such as persistent fatigue, cognitive difficulties, or metabolic issues, should consider getting their NAD levels tested to determine if intervention is needed. The Intracellular NAD Test provides a precise measurement of cellular NAD levels, helping identify deficiencies that may benefit from targeted NAD-boosting strategies. For those with confirmed low NAD levels, implementing appropriate interventions can help restore optimal cellular function and improve overall wellbeing.
