GREAT!! I have been taking NAC N-Acetyl-L-Cysteine for a week now! Lesson learned - RESEARCH! Thanks for the info and website!

ok..I appreciate this info greatly, though, I am curious if you may have read about difference between n-acetyl-cysteine and l-cysteine.....or difference between n-acetyl-cysteine and n-acetyl-l-cysteine....I am wanting to get going on taking one, I have now n-acetyl-l-cysteine that I bought just before I found your message. And definetely don't want my facial hair to grow more. Could you please respond because it will nt only help me but possibly many others, thank you much

I'm not sure what research you are reading, but N-acetyl L-cysteine and N-acetylcysteine are essentialy identical anti-oxident and liver cleanse and precursors to Glutathione. L-Cysteine is just the more stable version of Cysteine that's converted to L-cysteine as needed by the body. Supplemental forms of NAC therefore use L-cysteine instead. I'm not sure how one will promote facial hair growth (and no where else, as in selective hair growth?) over the other, or at all, since it's not a hormone. It is found in skin and hair, but creating growth where none now exists is not a feature of NAC. But it does promote collagen for better skin texture. Could you source your info? This doesn't sound right.
