Pantothenic acid and biotin

Alternative names 
Diet - pantothenic acid/biotin

Definition
Pantothenic acid and biotin are water-soluble vitamins, which means that they cannot be stored by the body and must be replenished every day. They help the body break down and use food. They are part of the B vitamin complex.

Function

Pantothenic acid is essential for the metabolism of food. It is essential in the synthesis of hormones and cholesterol. Cholesterol is needed by the body for the proper functioning of its cells’ membranes, particularly in the brain.

Biotin is essential for the metabolism of proteins and carbohydrates (like the other B vitamins), and in the synthesis of hormones and cholesterol.
