"Some molecular biologists are working on NAD (nicotinamide adenine dinucleotide), an enzyme central to metabolism that declines as we get older."

The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

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.
having said that NAD you know like Steve said Central molecule in thousands of chemical reactions really important good reason I know about good reason some reason to believe that NAD homeostasis declines with age like lots of many other things so it's plausible that if you fix that you can get benefits from it
