Niacin, also know as nicotinic acid, nicotinamide or vitamin B3, is used by bodybuilders when presenting themselves on stage due to its flushing effect from a megadose intake. One of the side effects of high intakes from a supplement is vasodialation of the capillaries. This helps the bodybuilder achieve a more vascular, fuller appearance on stage. Supplements of 200 - 400 mg are taken about 15 minutes before going on stage, and the effect lasts for approximately a further 15 minutes. The downside is intense itching, irritability and hotness.
