Quick Answer

No expert consensus. Attia classifies NAD+ supplementation as 'noise.' Patrick warns NMN may accelerate cancer. Huberman takes both but admits it's for energy, not longevity. Hyman recommends high-dose NMN. Save your money unless you have a specific reason to experiment.

on NMN / NAD+ overall

What Researchers Say

Peter Attia
Peter Attia Disagrees

Most skeptical. Classifies NAD+ as 'noise' on his evidence hierarchy. Cites ITP failure to show lifespan extension with NR.

Rhonda Patrick
Rhonda Patrick Nuanced

Leans toward NR for safety. Warns NMN may accelerate cancer. Notes both break down into nicotinamide which can inhibit sirtuins.

Andrew Huberman
Andrew Huberman Nuanced

Takes NR (500mg) and NMN (1-2g) daily for subjective energy. Explicitly not for longevity.

Mark Hyman
Mark Hyman Agrees

Most enthusiastic. Recommends high-dose NMN (1000mg) with ergothionine and resveratrol.

Detailed Answer

This is the most divisive supplement in the database at 2.3/5 consensus. Attia classifies NAD+ as "noise" on his evidence hierarchy, citing the ITP failure to show lifespan extension with NR. Patrick warns NMN may accelerate cancer and notes both precursors break down into nicotinamide which can paradoxically inhibit sirtuins.

Huberman takes both NR (500mg) and NMN (1-2g) daily but is transparent: it's for subjective energy, not proven longevity. Johnson's Blueprint protocol notably excludes both.

Hyman is the outlier advocate, hosting guests recommending 1000mg NMN. Exercise and fasting naturally boost NAD+ and should be prioritized over supplementation.

Related Questions

Is NMN legal to buy?

NMN's status is complicated. The FDA classified it as an investigational new drug. NR (as Niagen) remains widely available.

Do NMN or NR actually raise NAD+ levels?

Yes. Both raise blood NAD+ levels. The question is whether higher blood NAD+ translates to meaningful health benefits.
