A 2021 analysis of 22 best-selling NMN products found 14% with no detectable NMN at all, and another 64% below the test's reporting limit. A 2024 peer-reviewed study in GeroScience measured labeled-versus-actual content swinging from +28.6% to a full -100%. Separate testing from ConsumerLab found roughly 1 in 7 top-selling NMN products meeting their own label claim.\u003c\/p\u003e\u003cp\u003eEvery batch of this product runs through HPLC potency testing before release. The result ties to that batch's own lot number and its own Certificate of Analysis, available on request.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cp\u003eTake one capsule daily with a meal, preferably breakfast.
