has anyone had any experience with NAC for OCD???

Novel treatments for children with OCD are needed. N-acetylcysteine (NAC) is a natural supplement that acts as an antioxidant and a glutamate modulating agent. ... NAC has recently been demonstrated to be effective in a double-blind, placebo-controlled trial in adults with trichotillomania (chronic hair pulling).

NAC is an amino acid, something present in many foods, but supplements give you a higher dose than you’d get in your daily diet. It is usually taken in doses from 1000 to 2000 milligrams per day—usually in 600-milligram capsules taken 2 to 3 times a day, and other than mild gastrointestinal side effects NAC is usually well tolerated. [Note: Suffice it to say, you should talk to your doctor before taking this or other supplements to see whether they are suitable for you. In my psychiatric practice, I view a trial of NAC as similar to any other drug (or therapy) trial: You need to get a patient to an adequate dose for an adequate period of time, and carefully measure its effects on key symptoms (and monitor side effects) over a long enough duration to be able to conclude whether it’s helping.]

Thank you
