Just like all B vitamins, Pantothenic acid (vitamin B5) is also water soluble, meaning that the body does not store it. Vitamin B5 plays a crucial role in the production of red blood cells and hormones related to stress, which are manufactured in the adrenal glands. Another important function of vitamin B5 is to maintain a healthy digestive tract and aid the body in taking up other vitamins such as Riboflavin (Vitamin B2). Other than these functions, pantothenic acid is needed for the synthesis of cholesterol and coenzyme A (CoA). CoA is a chemical compound that helps enzymes to build and break down fatty acids.
