- Why Test Your NAD+ Levels?
- How It Works
- CLIA-Certified Accuracy
Your NAD+ levels are unique to you. Generic supplement dosing ignores this reality.
This CLIA-certified test measures your actual intracellular NAD+ levels from a small blood sample. You’ll receive specific dosage recommendations based on your results, not marketing claims.
Perfect for anyone taking NAD+ supplements, experiencing fatigue, or interested in longevity optimization. The test eliminates trial and error, helping you supplement smarter.
Stop guessing. Start testing. Get the personalized data your health deserves.
- NAD+ powers over 500 cellular processes including energy production, DNA repair, and brain function. NAD+ levels decline with age, especially after 30.
- Most people guess at NAD+ supplement dosages. The same amount could be perfect for one person but ineffective or excessive for another.
- Testing reveals your exact levels before you start supplementing. You’ll know if your current routine is working or if you need adjustments.
- Without testing, you’re flying blind with your health optimization.
No lab visits. No guesswork. Just clear, actionable data to guide your NAD+ supplementation strategy.

What is NAD+ and why is it important to measure?


NAD+ keeps your cells running smoothly. It’s involved in DNA repair, energy production, and fighting inflammation.
Your body uses NAD+ for more than 500 cellular activities every day. These include making ATP (cellular energy), supporting your immune system, and regulating sleep.
As NAD+ declines with age, you may notice lower energy, slower recovery, and reduced mental clarity. Many age-related health concerns trace back to insufficient NAD.
Testing reveals your current levels so you can take action. You can’t optimize what you don’t measure.
When NAD+ levels are optimal, your cells repair themselves better and produce energy more efficiently.
