Pantothenic acid, also called vitamin B5, is an antioxidant water-soluble vitamin needed to break down carbohydrates, proteins, and fats. Pantothenic acid comes in three forms, and it is alternately known as vitamin B5, panthenol and calcium pantothenate.Pantothenic acid is integral to many of the activities of enzymes in the human body. The body uses pantothenic acid to break down carbohydrates, proteins and fats for energy. Pantothenic acid functions as a component of coenzyme A and phosphopantetheine, which are involved in fatty acid metabolism.
Contraindications of Vitamin B5:
Pantothenic acid (Vitamin B5) converts into panthetheine, which is then converted into coenzyme A or CoA (pantethine is the stable form of pantetheine).
The usual therapeutic doses of Vitamin B5 are 50-200 mg. In some studies 1,000 mg and more were given daily for six months without any side-effects being produced.
