The Cata-Kor NMN Promise
Your NAD+ Levels Are
Dropping Every Year.
NAD+ is the coenzyme your cells use for energy production, DNA repair, and hundreds of other processes. The problem is it declines sharply with age, and there's only one efficient way to raise it back.
NMN (Nicotinamide Mononucleotide) is the most direct precursor to NAD+, converting efficiently once it enters your cells.
NMN Converts to
NAD+ Inside Your Cells.
You can't take NAD+ directly and have it work well. The molecule is too large to cross cell membranes efficiently. NMN is smaller and converts to NAD+ once it's already inside the cell, where it's needed.
- Supports cellular energy production
- Supports DNA repair mechanisms
- Studied in longevity research worldwide

What To Expect
What Customers Are Saying

I researched NMN for months before buying. The TMG inclusion was the deciding factor. Most brands don't include it and it matters. Two months in, energy is genuinely better.

The NSF certification is what sold me. I've been burned by supplements that didn't contain what they claimed. This one I actually trust. Quality feels premium.

Cata-Kor's glutathione was excellent so I trusted the NMN. Consistent with what I'd expect from this brand. Good quality, easy to swallow, no aftertaste.
