I might want to try! Do you have a particular product / brand you use that’s convenient to buy? I saw another comment of your mentioning then separated, is that how you take it?

Yes, I'm taking Glycine in powder (it's very cheap) from Vitality (UltraPure Glycine) and NAC from Chrisana - but I'm based in Switzerland. You should be able to find it anywhere, I'd think any brand would do just like any brand of vitamine C is likely ok.

NAC can have a number of surprising side effects for some, including anhedonia. Just be aware of the possibility before beginning to supplement it.
