A It's another water-soluble B complex vitamin. The word pantothenic is derived from the Greek meaning 'from
everywhere'. This name was given because the vitamin is present in all foods, although not always in substantial amounts.
Q. What role does pantothenic acid play in the body?
A Pantothenic acid is involved in proper skin growth and nerve function, and in maintaining the health of the adrenal glands. If there is pantothenic acid deficiency these glands may become enlarged, reddened and prone to hemorrhage. Pantothenic acid is known to be involved in the production of cortisone and two other related hormones produced by the adrenal glands. These hormones play an important role in metabolism and in the body's reaction to stress, including inflammation.
Claims that pantothenic acid prevents or alleviates arthritis have been examined in several studies, One double-blind study claimed 'highly significant effects for oral calcium pantothenate [a form of pantothenic acid] in reducing the duration of morning stiffness, degree of disability and severity of pain' in patients suffering from rheumatoid arthritis, a form characterized by inflammation in the joints and elsewhere in the body.
Q. Does it do anything else?
A. Yes. Like other B vitamins, pantothenic acid plays a vital role in energy metabolism. It's essential for the breakdown and release of energy from carbohydrates, fats and proteins.
