Pantothenic acid is vitamin B5. It is widely found in both plants and animals including meat, vegetables, cereal grains, legumes, eggs, and milk. 

Pantothenic acid helps the body utilize carbohydrates, proteins, and lipids. It is also important for maintaining healthy skin. Vitamin B5 is available as D-pantothenic acid, as well as dexpanthenol and calcium pantothenate, which are chemicals made in the lab from D-pantothenic acid.

People most commonly use pantothenic acid for pantothenic acid deficiency. Dexpanthenol, a chemical similar to pantothenic acid, is used for skin irritation, nasal swelling, wound healing, and other conditions.
