NAD+ is the longevity molecule. NMN raises it, and an at-home finger-prick test measures it.

In a randomized, placebo-controlled trial, 1,000 mg of NMN a day raised blood NAD+ to about double the placebo group in 14 days. That's the dose in every serving of NMN-99, verified at 99+% pure.

Run the NAD+ test before you start, so you have your own number to compare.

In the first two weeks, NMN-99 starts rebuilding your NAD+, and most people feel a difference in energy.

After that, your NAD+ stays up and keeps DNA repair running. You won't feel this part, which is why the NAD+ test matters.

At 4 months, while you're still taking it, run the same NAD+ test again at the same lab, and compare.
