I've tried unsuccessfully to find out whether niacin is as effective as a statin in decreasing inflammation. As it turns out, I'm taking niacin, rather than statins, because I think its "vasodilation" effect might help that neurological micro environment, and its easier to get as well, and maybe also helps depression. I take 100 mg x 3 times per day. Unfortunately I'm feeling rather crappy so I'm not a real testimony for its effectiveness. And, I think niacin shares the risk of statin in long term use/liver damage.
