NAD+ Supplements: Hype vs. What the Latest Research Shows

The New York Times piece digs into recent studies that question whether over‑the‑counter NAD+ precursors like NMN or NR actually boost cellular NAD+ levels enough to impact aging. It points out that many trials show modest or no changes in blood NAD+ and that the touted anti‑aging benefits are still mostly speculative.

Not gonna lie, I was hoping the hype would translate into a real edge for my sleep and recovery. After a few months of a 250 mg NR regimen I didn’t notice any clear shift in energy or muscle soreness, and my recent blood work showed NAD+ staying flat. The article’s focus on bioavailability and the need for high doses lines up with what I’ve read in the literature – you probably need a lot more than the typical supplement dose to see anything beyond a temporary spike. Still, the piece glosses over the possible synergy with exercise and diet, which might be where the real gains happen.

Anyone else tried a higher dose or combined NAD+ precursors with fasting or intense cardio? What changes, if any, did you see in your labs or daily performance?
