Mechanism of Action
How It Works
NMN Absorbed
NMN crosses the intestinal wall and enters the bloodstream within minutes of ingestion.
NAD⁺ Levels Rise
NMN is converted to NAD⁺ inside your cells, restoring levels that decline with age.
Sustained Results
With consistent use, elevated NAD⁺ supports energy, DNA repair, and cellular longevity.
Clinical Results
NAD⁺ Levels Over Time
Based on Yoshino et al. — mean whole-blood NAD⁺ relative to Week 0 baseline (n=127)
What's Inside
Science-Backed Ingredients
The NAD⁺ Precursor
Nicotinamide Mononucleotide is the most direct precursor to NAD⁺, rapidly converted inside cells to restore energy metabolism and DNA repair capacity.
Sirtuin Activator
Polyphenol found in red grapes that activates sirtuin proteins — the cellular 'longevity switches' that depend on NAD⁺ to function, amplifying NMN's benefits.
Absorption Enhancer
Patented black pepper extract clinically shown to increase bioavailability of nutrients by up to 20×, ensuring more NMN and Resveratrol reach your cells.
