Niacin, also called nicotinic acid, is a white, crystal-like vitamin of the B complex group that dissolves in water, and is usually found in various plant and animal tissues.
Niacin is useful in the breakdown and use of all major foods.
Niacin, in the form of nicotinic acid, can produce a niacin flush.
This typically happens when the dosage is 50 mg or higher.
This is a redness, warmth, and itching to the skin.
This reaction is not necessarily caused from an overdose of niacin.
The flush is the result of vasodilation.
A vasodilator relaxes the smooth muscle in blood vessels.
This causes them to dilate which leads to a decrease in blood pressure.
While some find this feeling uncomfortable, it is usually harmless.
