Pantothenic acid (as calcium D-pantothenate)

Pantothenic acid, also known as vitamin B5, is an essential B complex vitamin that is a component of coenzyme A (CoA), a molecule that is involved in the metabolism of fat, carbohydrates and proteins 1.* Rich food sources of pantothenic acid include chicken, beef, potatoes, oat cereals, tomato products, liver, kidney, egg yolk, broccoli and whole grains. In commercial supplement products, pantothenic acid is available as calcium or sodium D-pantothenate or as pantothenol. Pantothenic acid is frequently used in combination with other B vitamins in vitamin B complex formulations.

The U.S. Food and Drug Administration (FDA) has established a Reference Daily Intake (RDI) of 10 mg pantothenic acid for adults and children 4 or more years of age (21CFR101.9). RDIs are a set of dietary references for essential vitamins and minerals that are considered amounts sufficient to meet the daily requirements of healthy individuals. RDIs serve as the basis for calculating the percent daily value (%DV) amounts found on dietary supplement and food labels.

Calcium D-pantothenate, or D-calcium pantothenate, is the principal supplemental form of the water-soluble vitamin pantothenic acid. It is often available in multivitamin and B-complex products 2. Calcium pantothenate is considered generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in foods (21CFR184.1212) 3.
