contains niacin (B3)
20 minutes after taking this my body started to tingle and my face, hands, and knees turned bright red ~ classic niacin rush.  Seeing as most supplements now contain niacinimide, which does not induce the same effect, I would guess they do so to make it feel like you're having some sort of energy rush.  I think it's a cheap trick and that there should be a warning on the label.
