If a celebrity takes NMN, that's the evidence

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. Celebrity use is an endorsement, not a trial. FTC endorsement and health-claim guidance are the receipts. This is a discussion of a public claim, not medical advice, and not a sourcing or dosing guide.
