Calcium and sodium D-pantothenate, the calcium and sodium salts of pantothenic acid, are also available as supplements (4, 21). Supplements commonly contain pantothenol, a more stable alcohol derivative, which is rapidly converted to pantothenic acid by humans. However, it is not yet known to which extent bacterial synthesis contributes to pantothenic acid intake in humans (16, 34). The uptake of biotin and pantothenic acid in cultured colon cells by a specialized transporter suggests that humans may be able to absorb intestinal produced pantothenic acid and biotin. Some vitamin B5 is synthesized by the intestinal bacteria that normally colonize the human colon (‘large intestine’). Freezing and canning of foods result in similar losses (12). Whole grains are major sources of pantothenic acid, but processing and refining grains may result in a 35% to 75% loss (21). Liver and kidney, yeast, egg yolk, broccoli, peanuts, fish, shellfish, chicken, milk, yogurt, legumes, mushrooms, avocado, and sweet potatoes are good sources of vitamin B5 (20, 21). Vitamin B5 (pantothenic acid) is available in a variety of foods, usually present as coenzyme A (CoA) or phosphopantetheine (20).
