Frequently Asked Questions

What is NAD?

NAD is a coenzyme found in all living cells. It plays an essential role in many cellular processes such as repairing damaged DNA to prevent cancer, getting rid of aging (senescent) cells, mitochondrial function, regulation of sleep and immune response, and reduction of inflammation and free radicals. NAD catalyzes reactions for more than 500 enzymes, including those involved in the production of cellular energy (ATP). Deficient NAD levels are linked to the loss of function and vitality as well as many age-related diseases.

What are the potential benefits of optimizing NAD levels?

NAD optimization is the first step to better health and longevity. There are numerous benefits, including increased energy, better sleep, improved performance, reduction in muscle and joint pains, enhanced immunity against infections, reduced inflammation, reduction in insulin resistance, clearer mental clarity, and improved liver function. Actual benefits may vary from person to person, and individual health conditions may influence the impact.

What are the signs of low NAD levels?

The most common signs include chronic fatigue, lack of energy, poor performance, lack of mental clarity, sleeping issues, and poor health in general. However, you may not show any symptoms while your NAD levels are already low.

At what age do NAD levels begin to decline?

For many, NAD levels experience a sharp decline in their late twenties. Roughly 25% of younger individuals also have suboptimal or deficient NAD levels. The vast majority of people in their 40’s and older are deficient in NAD. The best way to determine whether you need to elevate NAD levels is by taking a Jinfiniti NAD test, the first and only NAD test available to doctors and customers.

Are NAD tests right for everyone?

Yes. All adults should take an NAD test to help determine whether their NAD level is within the optimum range or if supplementation is needed. If you already take NAD supplements or other products, a test will help determine whether or not they are working for you, and help you decide if you should change the product or dosage for better NAD optimization. This is essential because most NAD products on the market do not work as intended or cannot optimize NAD levels in most individuals.

What is the best way to optimize NAD levels?

The most efficient way is through supplementation with NAD precursors — building blocks that our cells use to make the NAD molecule. NAD precursors include nicotinamide mononucleotide (NMN), nicotinamide riboside (NR), nicotinamide (NAM) and niacin (nicotinic acid). Studies have shown that NMN, especially, certain NMN formulations like Jinfiniti’s Accuri™ Vitality Boost, is the most efficient way to raise one’s NAD levels and to gain functional benefits.

The other ways known to raise NAD levels include the NAD molecule (delivered orally, intravenously, or by injections and patches), inhibition of the enzymes that degrade NAD, or increasing the enzymes that make NAD. Based on our data, the efficacy of these approaches is variable depending on the products and the users, and often unproven. It is important that users test the efficacy of their chosen products, ideally through NAD blood test, to find out whether a product is working or not.

Intravenous infusion of NAD, which has become very popular among some circles, does NOT elevate intracellular NAD levels. Although it can offer clinical benefits for some diseases such as neurological conditions and certain infectious diseases like Lyme’s disease. For longevity, wellness and performance purposes, elevation of intracellular NAD is critical. At a minimum, you should consider the combination of intravenous NAD infusion and oral supplementation with NAD precursors, if intravenous NAD does offer certain benefits to you.

Subcutaneous injection of NAD only increases intracellular NAD levels modestly and rarely optimizes the NAD levels.

Can I purchase NAD supplements from any vendor?

There are many different products, brands, and delivery routes. The products on the market are extremely variable in terms of efficacy, much of which has not been tested in clinical studies. Furthermore, a product that works well for one person may not work for others. You should find out whether your chosen product works for you by testing your NAD levels.

Why should I choose the Jinfiniti’s NAD supplements?

Jinfiniti’s flagship NAD supplement, the Accuri™ Vitality Boost, has been extensively tested in clinical studies as well as by large numbers of consumers. It is a patent-pending formulation consisting of NMN and a proprietary vitality lift blend (creatine monohydrate, D-ribose, and nicotinamide). It allows optimization of NAD in about 90% of our customers based on our studies and consumer data. Additionally, almost all customers with optimized NAD levels experience clinical improvement in other areas of their health and performance. We work with each customer to find a satisfactory solution and offer a total guarantee of NAD optimization with a money-back guarantee.

What is the best approach for taking Jinfiniti NAD supplements?

The Jinfiniti NAD supplement, Accuri™ Vitality Boost, is a powder that can easily be dissolved in water. The powder form is preferred because it does not contain any other substances or fillers that are normally used to make capsules, and the dosage can be adjusted easily. Simply dissolve the desired amount of powder in room-temperature water and drink it slowly. Keeping the solution in the mouth for 30-60 seconds for each sip can increase absorption via the sublingual and mucosal routes and can be helpful for brain function. We recommend taking two doses daily, one in the early part of the day, and one in the evening. However, you can take the Vitality Boost at any time, with or without food. It is best to take the product before you feel tired and need a boost of energy. For those with sleeping issues, take it right before bedtime to help you sleep.

Are there side effects or health risks to taking NAD supplements?

There are no known side effects associated with taking safe dosages of high-quality NAD supplements. We recommend caution for patients with active cancer because it is currently unknown whether NAD supplements are beneficial or harmful to cancer patients. NAD can boost antitumor immunity (good for survival) and possibly accelerate cancer cell proliferation (bad for survival). You can find more information on this topic on our Learn page.

Does NAD supplements interfere with my current vitamin regimen?

NAD supplements may improve the efficacy of other supplements. Some people who are taking large doses of vitamin B3 (Niacin), a form of NAD precursors, may have high levels of NAD and may not need to take other NAD precursors. Testing for NAD levels will help decide whether extra NAD supplementation is needed and how much.

Will I feel different or better once I have optimized my NAD levels?

Most people taking our Vitality Boost NAD supplements feel a clear difference. The improvement may be immediate or may take 2-3 months, depending on each individual’s condition. Generally, people who have severely deficient NAD levels and have increased their NAD to above 50µM (micromole) notice clear improvements. However, people who already have relatively high NAD levels, and/or who do not have any specific complaints, may or may not experience a noticeable difference.

Can I have too much NAD?

Yes. However, scientists have not yet determined how much is too much. We recommend staying within 100μM. This does not mean levels above 100μM are harmful. Some customers with naturally occurring NAD levels greater than 100μM have seen no adverse effect.

How would I know if I’m allergic to NAD supplements?

We are not aware of any allergic reactions to NMN products of high quality, and we do not expect allergic reactions to high-purity NMN or ingredients in our Vitality Boost product. If you are concerned with potential allergic reactions to a product and want to try the product, you may want to start with a lower dose and gradually escalate the dosage over time to assure a smooth transition to optimized NAD.

Once my NAD levels are optimized, do I need to continue with supplements?

Yes, it is recommended to continue taking the supplement after NAD optimization. After four weeks of stopping NAD supplementation, levels typically return to baseline, sub-optimal levels.

How often should I test my NAD level?

It usually takes only 2-4 weeks for the supplements to raise your NAD. It’s ideal to take an NAD test before starting an NAD optimization program. Then, to make sure that your chosen product is working, we advise another test at about the four-week mark. Once your NAD is optimized, you only need to test again 2-3 times a year. You may need to test with different regularity if your health status has significantly changed, or you have changed the types and dosage of NAD products, or other supplements, medicines, or lifestyle.

At what age should I begin to take NAD supplements?  

The proportion of people with NAD deficiencies increases with age. Some people have seen a sharp decline in NAD starting in their late twenties. For those significantly older, most are deficient in NAD. There is not an upper age limit to NAD supplementation.

There is very limited data on the potential benefits or harm to teenagers, children, and infants. Our extensive data indicates that roughly 25% of teenagers are already suboptimal or deficient in NAD levels, but there is no official recommendation from any medical organizations in this regard. Young people with severely deficient NAD usually have major health issues. We believe that teenagers and young adults with deficient NAD levels can benefit from NAD supplementation.

There is no data on infants. We do not recommend NAD supplementation by infants unless the NAD level has been determined and NAD treatment is recommended by a medical professional.

Does NAD interact in any way with prescription drugs I may be taking?

There are no known adverse interactions between NMN and prescription drugs. Our data suggests that NAD optimization may improve the efficacy of certain health procedures, such as therapies for inflammation and oxidative stress and cellular senescence. Further studies are needed to define these potential benefits.

Do you offer a money-back guarantee for the Vitality Boost supplements if my NAD level does not reach the optimum range after using the supplement?

Absolutely! If you take our Vitality Boost product and follow the recommended schedule and dosage, and your NAD does not reach the optimum range as determined by our intracellular NAD test, we will work with you to find a personalized solution to get your NAD optimized, or we will refund your first purchase of the supplements.
