niacin
Metabolism-essential B-vitamin
Niacin is vitamin B3, an essential nutrient found in meat, fish, and grains.
The body uses it to convert food into energy and maintain healthy skin and nerves.
Severe deficiency causes pellagra.
In high doses, niacin is prescribed to lower cholesterol, though it often causes flushing—a harmless but uncomfortable warmth and redness of the skin.
