First Week of GlyNAC – Margin of Energy and GI Upset

Posted by greg208 in Longevity & Anti-Aging - 5 points, 4 comments.

I just kicked off a GlyNAC stack and wanted to share how it’s gone so far. 5 g dessert‑size NAC for my 70‑kg frame. For the first few days I felt my usual post‑shift fatigue lift a bit, even when I didn’t push extra at the gym.

The brain felt a tad sharper, and my digestion hasn’t been as cranky as BNP‑2 or Statin surprises. The only thing I’ve noticed is a mild, slightly sulphur‑y odour on my breath after the NAC dose and a slight loose stool on day three. Not a big deal, but I’m watching the gut.

Anyone else on GlyNAC? How did you split it? Do you use any antioxidant boosters to keep the gut happy? Also, curious if you pair it with the low‑dose rapamycin pulse I’ve seen some talk about – just keen to know if mixing the two is safer or better.

  • kayla_s: I’ve been on GlyNAC for a few months and I keep it in two splits, 2.5 g in the morning and 2.5 g in the evening, usually with food to cut down on the sulfur breath. I didn’t notice any loose stools with that schedule, and I keep a little vitamin C or alpha‑lipoic acid on hand because it seems to help keep the gut lining calm. I’ve not mixed it with rapamycin myself, but the two don’t have any glaring pharmacologic clashes, so I don’t see a safety problem, though it’s worth double‑checking with a
  • greg208: I’ll try the 2.5 g split you suggest, morning and night with a proper meal – that should help the sulfur breath, as it does for you. I’ll also keep a small bottle of vitamin C on hand and maybe a touch of alpha‑lipoic acid; I’m keen to see if that keeps my gut lining calm after the loose stool I had on day three. As for rapamycin, I’ll chat with a clinician first, but I’ll keep an eye on any overlapping side‑effects.
  • ivy_mobility: I’ve tried a similar split – 2 g NAC with breakfast and 2 g glycine before bed – and the sulfur breath faded after a week. Adding a pinch of vitamin C with the morning dose kept my stomach settled, though I still get a tiny gurgle if I take it on an empty stomach. ⚖️👀
  • greg208: Thanks for the tip, ivy. I haven’t split the dose yet – just 5 g NAC all at once – so I’ll try your 2 g/2 g split. The sulfur breath was a bit annoying, so I’ll add a pinch of vitamin C with the morning dose and see if the gurgle on an empty stomach goes away. Will keep an eye on the energy swing and stool consistency. Do you notice any change in sleep or gut after the bedtime glycine?
