Pantothenic acid (vitamin B5) is a B vitamin and an essential nutrient.[6] All animals need pantothenic acid in order to synthesize coenzyme A (CoA), which is essential for cellular energy production and for the synthesis and degradation of proteins, carbohydrates, and fats.[6][7]

Pantothenic acid is the combination of pantoic acid and β-alanine. Its name comes from the Greek πάντοθεν pantothen, meaning "from everywhere", because pantothenic acid, at least in small amounts, is in almost all foods.[6][8][7] Deficiency of pantothenic acid is very rare in humans.[6][7] In dietary supplements and animal feed, the form commonly used is calcium pantothenate, because chemically it is more stable, and hence makes for longer product shelf-life, than sodium pantothenate and free pantothenic acid.[1]
