What your NAD+ levels means

NAD+ (nicotinamide adenine dinucleotide) is the molecule your cells depend on to produce energy, repair DNA,
and regulate hundreds of metabolic processes.

It declines measurably with age — often beginning as early as your 30s — and low levels are closely
linked to persistent fatigue, cognitive fog, slower recovery, and accelerated biological aging.

Your result is reported in micromolar (uM). Here’s how to interpret where you fall:

Severely Deficient

0–20 μM

20/100

Severely impaired energy production, causing fatigue, poor recovery, and depletion. Guided NAD+ repletion is recommended.

Deficient

20–30 μM

30/100

Low NAD+ function leads to energy dips, brain fog, and slow recovery. Improvement is noticeable once levels reach optimal.

Suboptimal

30–40 μM

40/100

Insufficient NAD+ for optimal performance, causing mild fatigue & mental inconsistency. Targeted supplementation can improve levels in 4–6 weeks.

Optimal

40–100 μM

60/100

Optimal NAD+ supports steady energy, sharper cognition, and better resilience. Maintaining this range is the goal.

Too High

Above 100 μM

100/100

Excess NAD+ offers no added benefit. Reduce dosage if needed—testing ensures precise, optimal levels.

This is real participant data from our Vitality+ NAD+ Booster clinical study. 85% of participants reached optimal NAD+ levels (40-100 M) within 4 weeks.

The only test that tells you if
your supplements are working

Most people take NAD+ precursors — NMN, NR, or multi-pathway
formulas — without any way to confirm their levels are actually
responding. Dosing recommendations on supplement labels are
educated estimates. Your biology is not average.

This test changes that. Measure before you start. Retest after 4–6 weeks
of supplementation. See exactly where you are, whether your current
dose is sufficient, and what to adjust. That’s not a supplement.
That’s precision medicine.

Jinfiniti’s clinical data — conducted on our own Vitality↑® NAD+ Booster — found that 85% of participants reached optimal NAD+ levels (40–100 μM) within 4 weeks when dosing was guided by testing. That result is not achievable with guesswork.

What makes this test different from a standard NAD+ blood test?

Most NAD+ tests measure NAD in serum or plasma — the liquid part of your blood. This test measures NAD+ intracellularly, meaning inside your red blood cells. That’s where NAD+ is actually used for energy production. Intracellular measurement gives a far more accurate picture of your real cellular energy status.

Who should take this test?

Anyone currently taking an NAD+ supplement who wants to know whether it’s working. Also anyone experiencing persistent fatigue, cognitive fog, or slow recovery who suspects a cellular energy issue — and wants data before committing to a supplementation protocol.

How do I collect my sample?

The kit includes everything you need for a simple finger-prick collection at home. No clinic visit, no blood draw, no fasting. Instructions are included and the process takes only a few minutes.

How long until I get my results?

Results are typically delivered within approximately one week of your sample arriving at the lab.

What does my result tell me about dosing?

Your result comes with personalized dosing guidance based on where your level falls relative to the optimal range (40–100 μM). If you’re already supplementing, it tells you whether your current dose is sufficient, too low, or — in some cases — higher than necessary.

Can I retest to track progress?

Yes — retesting is the point. We recommend retesting 4–6 weeks after starting or adjusting supplementation to confirm your levels have moved in the right direction. Many customers test quarterly as part of an ongoing optimization protocol.

Is there a bundle option that includes the test and a supplement?

Yes. The NAD Membership includes Intracellular NAD® Test and Vitality↑® NAD+ Booster shipped every month — designed to establish your baseline, support supplementation, and confirm your results.
