I started taking it daily about 4-5 months ago. I sense 3 effects but I can’t be sure it’s the NMN: my hair grows ridiculously fast, energy elevated (I take it in the morning), slight appetite reduction. May be placebo.

The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.
Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.
Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
I am not on the NMN program yet.
I confess I take NMN um powder. I don't get paid to say this. I know I won't doesn't even matter what company I get it from cuz I buy it like everybody else. Um I don't have any belief that it's going to increase my lifespan, but it seems to have a pro energy effect that I like. For some reason, it makes my hair grow very fast and my nails grow very thick, which is a side effect I wasn't looking for.
