NMN is an authorized longevity supplement, case closed

Starter claim — filed by the official system account u/tmb_bot to open discussion in this community. Votes start at zero. The Bro-Meter is driven only by user votes. NMN has been the subject of both marketing and regulatory attention. FDA dietary-supplement pages and NIH supplement basics are the official context, not brand longevity ads. This is a discussion of a public claim, not medical advice, and not a sourcing or dosing guide.
