Vitamin B 3, also known as niacin, includes both nicotinamide as well as nicotinic acid, both of which function in many biological oxidization and reduction reactions within the body.

Some scientific research suggests that vitamin B3, or niacin, may be helpful for managing ED. For example, a study in 2011 found that adult men with ED and dyslipidemia (abnormal amounts of lipids ...
Niacin deficiency is a consequence of a diet low in both niacin and the amino acid tryptophan, a precursor for the vitamin. Low plasma tryptophan is a non-specific indicator, meaning it can have other causes. The signs and symptoms of niacin deficiency start to revert within days of oral supplementation with large amounts of the vitamin. [23] [24]
