First time starting GlyNAC: Dosage, timing, and side‑effects?

Posted by coastal_chemist in Beginner Questions - 2 points, 0 comments.

I’m 170 lbs, 44, and just started looking into GlyNAC after reading about its glutathione‑boosting claims. The protocol I saw says glycine 100 mg/kg and NAC 100 mg/kg per day, split 1–2 times daily. That’d put me at about 350 mg of each per dose, but I’m not sure how to split it – two times a day or a single big dose in the morning?

I also read that NAC can cause a sulfur smell and sometimes loose stools at higher doses, so I’m wary of hitting that “high” too quickly. I want to keep an eye on my gut and see if I notice any headaches or GI upset. I’m thinking of taking the first dose after breakfast and the second around lunch, but I could be off.

What are the practical tips for timing, and how do you monitor whether the treatment is doing anything, given that you can’t really measure glutathione in a quick home test? Anyone else been walking this path?
