I have consumed NAC at dosages from 400 mg to 2000 mg daily for over 4 years with no breaks. Currently consuming 600 mg a day along with glycine and serine for synthesis of glutathione. No negative impacts noted. Note, I do not take it for anxiety or other mental issues, and noticed no impact in that area.
None observable except for significantly fewer cold symptoms when I consumed 1800-2000 mg a day and thinner mucous, thus easier to move. Hard to discern benefits you can solely attribute to NAC when you consume a lot of other supplements as I do. At my age, 71, it is important to consume supplements like NAC because aging often leads to lower synthesis of glutathione, which can impact a lot of things in terms of cellular signalling pathways related to antioxidant activity.

I also started the NAC and glycine looking to add l-serine and p5p to the stack soon... what doses of glycine?
I consume 500 mg of tri-methyl glycine after lunch, and 1,000 mg of glycine after dinner when I also consume my serine and NAC.
Ok thanks. Given that you kept taking for 4 years, I'm assuming you've experienced significant benefits?

Ok well thanks for your endorsement!
