Support for NMN is thin so far, with little human data.
Who is behind it
Voices including a nutritional sciences PhD, a board-certified internal medicine doctor and a registered holistic nutritionist.
How strong the research is
Mostly expert experience so far, with published research still catching up.
In their words
“My strong suspicion is that NMN is not absorbed intact. It's broken down into NR and it's absorbed intact as NR.”
a nutritional sciences PhD
Methyl donors neutralize homocysteine, a cardiotoxic byproduct of NAD+ increase, enhancing anti-aging benefits of NMN.
With care
Some of the minds attach conditions. These are worth reading before you begin.
Likely absorbed as NR after phosphate cleavage in intestines, but less studied and may be poorly absorbed in people with intestinal damage.
The expert uses NMN to augment NAD which gives more morning energy and some unexpected effects like thicker nails and faster hair growth, but does not claim it increases lifespan.
Human studies show NMN raises NAD safely but do not confirm improvements in endurance or insulin resistance.
