Most people don’t know this, but NAC reduces bad Estrogen and flushes it out. I found out I was Estrogen dominant, (many of us have bad Estrogen). Well, NAC is a huge body detoxing supplement. As it cleans out our liver, that’s how it filters out the bad hormones, & anything else that NAC recognizes as a toxic “invader”. My only advice is to go slowly. 1 capsule for the first 2 weeks, then increase. This will prevent you from having any detox symptoms. Hope this helps. :)


My partner has had some behaviors since childhood that haven't ever been diagnosed (skin-picking, OCD tendencies, and tics/shakes that seem like autism-related) and after seeing a ton of different doctors throughout his life, a behaviorist recently suggested NAC. He started with 600mg/day and increased to twice a day with no negative side effects. He noticed ALL of his behaviors decrease within days and when he misses a day, he is very aware of the difference. He is still experimenting with dosage and timing, but so far, this is basically the "cure" we'd been looking for!!

My husband has Parkinson's disease one of the components in his case is obsesive/compulsive behavior. He does various things like constantly folding paper or starts weeding and can't stop. NAC helps. He still does it but stops when asked where before he started taking NAC it was almost impossible to get him to stop with out physical intervention.
