The Jinfiniti NAD+ Test is the first clinically approved and most trusted NAD+ testing solution worldwide. Whether you’re taking NAD+ supplements, dealing with chronic fatigue, navigating age-related conditions, or aiming to improve athletic performance, this comprehensive test delivers actionable data to guide your personalized NAD+ optimization journey. Since every person’s needs differ, our test identifies the perfect dosage for you—ensuring effective, non-toxic, and transformative results.

Step into the future of healthcare and invest in your well-being. The Jinfiniti NAD+ Test is your powerful tool to reclaim energy, enhance recovery, and support healthy aging—because it’s not just about living longer, but living better.

Reasons to take an NAD+ test
  • NAD is a coenzyme necessary for the function of over 500 different cellular activities including  energy production, repair of damaged DNA, sleep, brain function.  NAD optimization is the starting point for better health and performance and extended longevity.
  • Unfortunately, NAD declines with age and most people over 30 years of age may be deficient in NAD without supplementation.
  • Taking NAD products without proper testing is unlikely to to provide full benefits from optimized NAD as different people need different dosage. 
  • Testing NAD is the only way to find out the optimal dosage for you.  Ideally one should measure at baseline and after supplementation. At the minimum, one must measure after supplementation because the same dosage could be optimal, ineffective or toxic for different people. NAD tests will give you actionable data for NAD and health optimization.
Why Choose the Jinfiniti NAD+ Test?
For decades, NAD test was desired by many doctors and consumers who realized the critical importance of NAD. However, the first clinical grade test only became available in 2019 and was developed by Jinfiniti.
Clinically Proven and Widely Adopted

We pioneered the first clinical-grade NAD+ test and currently administer over 90% of all NAD+ tests.

Unmatched Expertise
Backed by comprehensive studies and practical guidelines, no one else has the knowledge to guide your NAD+ optimization like we do.
Precise Dosage Guidance
Measure your NAD+ levels before and after supplementation to ensure effectiveness, avoid toxicity, and maximize health benefits.

Intracellular NAD® Test

What is NAD and why is it important to measure?

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.

The good news is you can optimize your NAD levels
The best way to boost NAD is a combination of NAD precursors and healthy lifestyle.

NAD precursors
Various NAD precursors help cells produce NAD. Nicotinamide riboside (NR), a two-step precursor, efficiently boosts NAD levels, while a one-step precursor is the most effective supplement. Vitamin B3 compounds like nicotinic acid (NA) and nicotinamide (NAM) are generally less effective NAD precursors for most people.
NAD+ or NADH
NAD+ and NADH are forms of NAD used via IV, subcutaneous, and oral routes to boost NAD levels and treat health conditions. Our studies show IV NAD+ doesn’t raise levels, subcutaneous injections provide modest increases, and oral supplements lack sufficient efficacy data.
Inhibit enzymes that consume NAD
NAD is broken down by enzymes like CD38, Sirtuins, and PARP. CD38, which rises with inflammation and aging, is a major NAD degrader. Supplements like quercetin and apigenin can inhibit CD38 activity in test tubes. While CD38 inhibition may boost circulating NAD levels, its effect on intracellular NAD remains unclear.
Boost enzymes that make NAD
NAMPT is a key enzyme for NAD production in our cells. Supplements, diet, sleep, and exercise can influence NAD-synthesizing enzymes and NAD levels, but alone, they may not be enough. A combination of NAD precursors and a healthy lifestyle is the best approach to optimize NAD levels.
