Vitamin B5

Last revised by Daniel J Bell on 2 Aug 2021

Vitamin B5 (pantothenic acid) is a water-soluble vitamin, part of the vitamin B complex, that is required to synthesize coenzyme A, a very important coenzyme in many cellular metabolic reactions.

Vitamin B5 deficiency (hypovitaminosis B5) is extremely rare.

There is no evidence of any deleterious effects from megadoses of pantothenic acid.
