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.
there's PARPs. PARP one was kind of the first one that was described, but there another 15 or 16 members of the PARP super family. Many of them don't polymerize ADP ribos, but they modify proteins with ADP ribos. So they they they cut NAD and they add an ADP ribos unit on something to do a signaling reaction. Um there's enzymes called certuins that use NAD. Um they very often remove a small modification on protein lysines. So acetil modifications on lysines, asil groups on

important enzymes that do that consume NAD. we have other enzymes that are involved in regulating our genes, right? Making sure they're active or not active and you know, so that's another role of NAD.
