What NAD+ is

Coenzyme, plain

Not a peptide at all. A coenzyme every cell uses to make energy.

The molecule the longevity field can't stop talking about.

Quick honesty: NAD+ is not a peptide. It's a coenzyme, a small helper molecule your cells use to turn food into usable energy.

NAD+ stands for nicotinamide adenine dinucleotide. Every cell runs on it. The catch researchers care about is that levels appear to drift down with age, which is why it became a centerpiece of longevity and cellular-energy research.

It lives on the Skin + Longevity shelf next to cellular-energy compounds like MOTS-c.

What it actually does

NAD+ is studied for its central role in energy metabolism, the chemistry of moving electrons around so cells can make power.

It's also a substrate for a family of enzymes (the sirtuins) that researchers tie to aging. So a lot of the work looks at NAD+ levels and how they relate to cellular-energy and longevity pathways. That's the mechanism. We're describing what gets studied, not promising an outcome.

Because it sits at such a basic layer of biochemistry, the molecule turns up across an enormous range of studies. How cells recycle their own building blocks. How they cope with stress. How they repair breaks in their DNA. How tissues respond as the years add up. Researchers track how its levels rise and fall through the day, how the body recycles it through what are called salvage pathways, and how efficiently those pathways keep running over a full lifespan. It is one of those quiet helper molecules that shows up almost everywhere you point a microscope once you start studying how a cell actually makes and spends its energy.

The research so far

NAD+ biology is one of the busiest areas in longevity research. You can dig into the literature on PubMed.

Energy metabolism

The electron hand-offs that power the cell.

Sirtuins

Aging-linked enzymes that use NAD+.

Research only

We stock it for research. The studies write the conclusions, not us.

The small molecule at the center of the longevity-energy conversation.

The backstory

NAD+ has been known to biochemistry for a very long time, but the longevity angle is what revived interest.

  1. An old molecule

    Identified in the early days of metabolism research.

  2. The aging link

    Renewed attention came from its tie to sirtuins and declining levels with age.

  3. Where it stands

    A central, heavily-studied molecule in longevity science. We're not telling you what it does for you, just where the studies look.

Buying NAD+ in Canada

The short version

Read the COA before you buy, not after
