Does niacin flush free work same as regular niacin?

Discuss with MD. Yes but Flush free has less side effects. Niacin is no good for lowering bad cholesterol. It may improve (a little) the good cholesterol and the best effect is on triglycerides. BUT, newer studies show NO benefits in mortality rates or frequency of heart attacks or strokes. Indication of Niacin has become more questionable since you may improve "numbers" but you do NOT improve outcomes.
