NR (Nicotinamide Riboside)
Another way to boost NAD+ — this vitamin B3 derivative has a solid body of research behind it and is one of the better-studied longevity supplements available.
Benefits

- +May support energy, metabolism, and healthy aging
- +Some evidence for improved insulin sensitivity
- +May support cognitive function as NAD+ declines with age
- +Has more long-term clinical trial data than NMN
- +May support mitochondrial health
