Pantothenic Acid - Benefits, Deficiency Symptoms And Food Sources
Alternative names :- Vitamin B5, Anti-stress vitamin
Pantothenic acid derives its name from its distribution in all foodstuffs (pantathen = everywhere). It was also known as filtrate factor' because the term vitamin B6 was originally applied to the heatresistant combination of riboflavin, niacin and vitamin B2 which were all adsorbed on fuller's earth; pantothenic acid was not adsorbed but passed into the filtrate. Interest in this factor was aroused by the observation that it prevented greying of fur in rats. The absence of this factor was known to. produce changes in the skins of chicks that superficially resembled human pellagra; hence, it was also known as chick pellagra factor.
Pantothenic acid is also used in the release of energy as well as the metabolism of fat, protein and carbohydrates. It is used in the creation of lipids, neurotransmitters, steroid hormones and hemoglobin.
Benefits and functions of Pantothenic acid
Pantothenic acid may have some benefit in rheumatoid arthritis. Research results are mixed, but overall not encouraging, with respect to claims that pantothenic acid enhances exercise performance. There is some animal and in vitro evidence that pantothenic acid may aid in wound healing. However, one human clinical study did not show a wound healing effect for oral pantothenic acid. A topical form of the provitamin, dexpanthenol (pantothenol) is used for the treatment of minor skin disorders, including for the promotion of wound healing. There is preliminary evidence that pantothenic acid may be helpful in treating those with hepatitis A and a suggestion from animal studies that it may be helpful in some with Duchenne muscular dystrophy. There is no evidence that it prevents loss of hair and graying of hair.
Recommended dosage of Pantothenic acid
No clear data exist on the daily requirement. An average diet contains 6-10 mg pantothenic acid, and this is evidently adequate. Cow and human milk yield 10-11 mg per 2500 kcal (10.5 MJ).

Pantothenic acid deficiency is extremely rare and is likely only to occur with starvation. Deficiency symptoms include fatigue, headache, and nausea.
