>>33288552 (OP)I've never heard of it being used for OCD.
I take NAC, 3 x 1g/day with an equal amount of glycine. The combination ("Glynac") has been show to increase glutathione production youthful levels in older people. Glutathione is "the master anti-oxidant" and mops up the oxygen radicals that cause many kinds of inflammation, which in turn are implicated, by inflammation and cell death, in many age-related disorders. I am remarkably free of the aches and pains that my contemporaries experience; skin un-wrinkled although you wouldn't mistake me for a young person. LOL.
Bottom line is that I see no reason not to try it if your condition might in any way have inflammation involved.
