Taking niacin for your cholesterol? This stuff from GNC is awesome. I’ve been taking 500mg of Niacin 2x a day for years now. As daily pill regimens go it’s relatively benign, but the 10 minutes or so of hot flashes and flushing 20 minutes after you take the pill sucks. I thought the no flush version from GNC would be a gimmick, and it’s a good bit more expensive, but man, it’s worth it. No flushing, no itching, no hot flashes. Well worth $15-20 more a month. If you’re taking Niacin you owe it to yourself to try this stuff.
