Not a peptide, but one of the most important molecules in the longevity conversation — here’s why.
A quick honesty note up front: NAD+ isn’t a peptide. It’s a coenzyme — but it’s become such a central character in cellular-energy and longevity research that it earns its place in the library. If you’re reading about ageing science, you can’t avoid it.
What it is
NAD+ stands for nicotinamide adenine dinucleotide. Think of it as a molecular shuttle that ferries electrons around inside your cells — a job so fundamental that without it, the process of turning food into usable energy simply stops. Every cell in your body depends on it.
Why researchers care
Two threads make NAD+ fascinating. First, it declines with age — cellular NAD+ levels fall as we get older, and a lot of research is asking whether that decline is a cause or a consequence of ageing. Second, NAD+ is the fuel for a family of enzymes called sirtuins, which are tied to DNA repair and cellular stress responses and are themselves a major longevity-research target.
A molecule that powers cellular energy, feeds the “longevity enzymes,” and runs low with age is, predictably, one of the most studied compounds in the field.
Where it sits
NAD+ belongs in the same cellular-energy corner of the library as MOTS-c — both sit at the intersection of metabolism, mitochondria and ageing research.
