The best food sources are brewer's yeast, wheat germ, wheat bran, royal jelly, whole-grain breads and cereals, green vegetables, peas, beans, peanuts, crude molasses, liver and egg yolk. Pantothenic acid supplementation is usually required for a desired therapeutic effect. The RDA for adults is 5mg but the optimal daily intake may be 100mg. Pantothenic Acid is water-soluble and stable in moist heat, but unstable in dry heat and acid or basic pH situations. Little is lost during normal cooking but 50% loss occurs in vegetables when they are frozen and 65% when they are canned. In addition, processed and refined grains lose about 50%, while processed meats lose up to 70% of vitamin B5.
Pantothenic acid is readily absorbed from the gastrointestinal tract. Before pantothenic acid is utilized it must first be converted to the sulfur-containing pantotheine. |
