Dietary sources rich in vitamin B5 include meats, liver, poultry, fish, milk and egg yolks. It can be found in many vegetables like cauliflower, broccoli, avocado and tomatoes. Whole grain breads, cereals, lentils and wheat germ are also good dietary sources of the vitamin. Vitamin B5 is also available in B complex supplements or sold individually as pantothenic acid. Dietary supplements are available in tablet, capsule, liquid or powder form and should be used under the supervision of a physician.

Vitamin B5 is essential for vital cellular processes like the conversion of carbohydrate, fat and protein into energy. The University of Maryland Medical Center reports that vitamin B5 is also essential for nervous system functioning and the healthy maintenance of skin, hair and eyes. Other functions of the vitamin include formation of red blood cells and sex hormones produced by the adrenal glands. Studies by Medline Plus suggest that vitamin B5 formulas administered intravenously or orally are used to treat deficiencies in malnourished patients.
Dosage
The daily adequate intake for vitamin B5 for adults is 5 mg daily. Pregnant or nursing women are required 7 mg per day, according to Medline Plus. Vitamin B5 supplements of 5 to 10 mg daily have been used in combination with the other water-soluble b-vitamins. Higher doses of vitamin B5 should be recommended by a physician. The University of Maryland Medical Center recommends taking supplemental vitamin B5 in a formula with the other B-vitamins to prevent imbalances.
