NAD+: How It Works and What the Research Shows
NAD+ is a coenzyme found in every cell, central to energy production and a favorite of the longevity movement. Here is how it works and what the research shows.
How NAD+ works
NAD+ is a coenzyme essential for turning nutrients into cellular energy and for DNA repair. Levels naturally decline with age, which is the basis for the interest in supplementing it.
What the research shows
NAD+ is a centerpiece of longevity research and is discussed widely by figures in that field. It is delivered through IV and injectable protocols, and the longevity community follows it closely.
Where it fits
NAD+ is the longevity anchor of the catalog, for those focused on cellular energy and healthy aging rather than weight or recovery.
Sourcing verified NAD+
Quality varies widely between sellers. Every Purivial NAD+ vial ships with a batch-specific COA showing HPLC purity of 99 percent or higher and mass-spec identity, so you know what is in the vial before it leaves the lab.
