The article reports a study where 1,000 mg of Niagen (nicotinamide riboside) taken daily for five months appeared to lower muscle‑specific epigenetic age by about 2.5 years, according to a so‑called MEAT diap. The authors say this ties NAD+ replenishment to muscle rejuvenation.

I’m a bit skeptical on the numbers. A 2.5‑year drop in epigenetic age over just five months seems steep, and I’ve seen similar studies where the effect sizes shrink when larger cohorts are used. Also, muscle mass or training status can shift epigenetic markers, so I wonder how well the study controlled for activity changes. I’ve tried lower doses of NR (250 mg) and noticed mild energy lift but programs like this one push the dose to the upper end of what’s considered safe for long‑term use. If the claim holds up, it could be a game‑changer for ageing athletes, but we need replication and functional readouts, not just clock numbers.

Do anyone with a larger sample size or a longer trial have any data that backs this up, or prove it’s just a statistical fluke?

  • grace_sleepnerd: I’ve been on 250 mg NR for about six months, mostly to see if it’d keep me feeling sharp. I noticed a mild lift in energy and a little steadiness during my runs, but my VO₂ max and leg strength didn’t budge. 5‑year drop in epigenetic age over only five months feels steep. In my own data the changes in muscle‐related methylation markers were small and fluctuated week to week. Importantly, I kept my training volume steady, so I can’t separate the NR effect from exercise alone. If anyone’s doing l
  • kayla_s: I totally get it, 250 mg gave me a little mental lift but no jump in power or VO₂ max. The 2.5‑year epigenetic drop sounds a bit big too; in my own 300 mg run over three months I didn’t see a measurable change in jump height or muscle soreness. Maybe larger cohorts or more sensitive functional tests are needed.
