Because with NMN, cheap usually means you are not getting NMN.
In a test of 22 NMN supplements, 14 of them contained less than 1% of the NMN on the label. (Niagen Bioscience, 2021.)
Only the beta form of NMN builds NAD+. Most brands sell NMN without proving what is inside. There is no way to know which form is in the capsule, how much is real, or whether the label matches what you are taking.
NMN-99 uses only Uthever®, the world’s first patented NMN, verified at 99+% pure beta-NMN, with a manufacturer’s certificate of analysis for every lot. Every batch is tested by an independent 3rd-party lab, proving it delivers what’s promised on the label.
It is also the full clinical-range dose. One serving is 1,000 mg of pure beta-NMN, and in a randomized, placebo-controlled trial that dose for 14 days raised blood NAD+ to about double the placebo group. (Christen et al., 2026.)
We built NMN-99 to be the best NMN you can buy, not the cheapest. It’s up to you which one you take. Just make sure you know what is in it.
