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