Why you can't just take NAD+.

The molecule you want more of isn't the one to swallow. Here's the three-step logic.

1

NAD+ is too large to absorb well. Taken directly as a supplement, very little reaches your cells intact.

2

NMN is one step before NAD+. It's the direct precursor, small enough to absorb.

3

Your body does the conversion. NMN becomes NAD+ inside your cells, where it's needed.

Pure NMN, nothing else. A full 500mg of pure NMN per capsule, zero fillers or blends. Every batch is independently lab tested and we publish the certificates. See the latest certificate →

Good to know.

What's the difference between NAD+ and NMN?

NAD+ is the coenzyme your cells actually use. NMN is the direct precursor your body converts into NAD+. Because NAD+ itself absorbs poorly as a supplement, taking NMN is how you support your NAD+ levels effectively.

How long until I notice anything?

Everyone is different. Many of our reviewers report changes between weeks three and six, and we suggest judging it over a full 90 days of daily use. That's exactly why the guarantee runs to 100 days.

How much NMN per day?

Each capsule contains a full 500mg of pure NMN, and the routine is one capsule a day, ideally at the same time each morning so it becomes automatic.

Is it tested?

Every batch is tested by an independent accredited laboratory before it goes anywhere near a bottle, verifying purity and that each capsule contains exactly what the label says. We publish the certificates on our transparency page.
