GlyNAC, Do the “anti‑aging” claims hold up for real‑world users?

Posted by liam_sleepnerd in Research & News - 3 points, 4 comments.

I stumbled across a paper in the Journal of Gerontological Medicine last month that pushed GlyNAC (glycine + N‑acetylcysteine) as a quick fix for age‑related oxidative stress. The study ran four weeks on 80 participants over 70, giving them 100 mg/kg of each compound daily, roughly 10 g of glycine and 10 g of NAC for a 70‑kg person. They reported restored glutathione levels, better mitochondrial ATP production, and even a modest lift in cognitive test scores.

com/peptides/glynac. I’ve been supplementing with a similar split dose for the past month, mostly to see if it gives me a better grip in the gym and smoother recovery after long runs. My HRV has been steadier, and I notice less post‑exercise soreness, but I’m not seeing any dramatic “reverse‑aging” signs.

The hype around instant anti‑aging seems a bit overblown, what’s the real ceiling’école? For those of you who’ve tried it, what tangible changes, if any, have you tracked in the first few weeks?

• hank_m: Tbh I've been on glynac about 10 g glycine and 10 g NAC a day for a month now, just to see if it helps with recovery after my long runs and the occasional strength session. I did notice my heart‑rate variability was a bit steadier on rest days and the muscle soreness after a hard trail run felt less brutal, but no dramatic “reverse‑aging” signs – my skin’s still the same, my hair’s still the same, and my memory quirks haven’t vanished. I’m tracking it with a simple log of soreness levels, energy
• busy_macros: Hey hank_m, I’ve been trying a similar split dose for a couple weeks and noticed my post‑WOD soreness eases a tad faster, but my sleep scores haven’t shifted much. Curious if you’ve seen any change in reaction time or focus during metcons?
• liam_sleepnerd: Tbh I haven’t tracked reaction time or focus metrics yet, so I can’t say whether I’m quicker or sharper in metcons erstellen. I have been noting a steadier HRV and a modest drop in soreness after long runs, but sleep scores stayed flat, just like yours. I’ll start timing my rounds and logging focus in the next week to see if any change crops up.
• liam_sleepnerd: Thanks for pointing out the log. openqa. My resting HRV has gone up about 4 bpm over the month and soreness went from a 6 on hard runs to a 3 after the same effort. What scale are you using for soreness, and do you see a shift in how long it takes to hit 90 % HRV after a workout?
