PANTOTHENIC ACIDVisit The Healthy Living Bookshelf:
What does it do? Pantothenic acid, also called vitamin B5, is involved in the Kreb’s cycle of energy production and is needed to make the neurotransmitter acetylcholine. It is also essential in producing, transporting, and releasing energy from fats. Synthesis of cholesterol (needed to manufacture vitamin D and steroid hormones) depends on pantothenic acid. Pantothenic acid also activates the adrenal glands.1 Pantethine—a byproduct of pantothenic acid—has been reported to lower blood levels of cholesterol and triglycerides. Where is it found? Liver, yeast, and salmon have high concentrations of pantothenic acid, but most other foods, including vegetables, dairy, eggs, grains, and meat, also provide some pantothenic acid.  Pantothenic acid or pantethine have been used in connection with the following conditions (refer to the individual health concern for complete information):
Who is likely to be deficient? Pantothenic acid deficiencies may occur in people with alcoholism but are generally believed to be rare. How much is usually taken? Most people do not need to supplement with pantothenic acid. However, the 10–25 mg found in many multivitamin supplements might improve pantothenic acid status. So-called primitive human diets provided greater amounts of this nutrient than is found in modern diets. Most cholesterol researchers using pantethine have given people 300 mg three times per day (total 900 mg). Are there any side effects or interactions? No serious side effects have been reported, even at intakes of up to 10,000 mg (10 grams) per day. Very large amounts of pantothenic acid (several grams per day) can cause diarrhea. Pantothenic acid works together with vitamin B1, vitamin B2, and vitamin B3 to help make the fuel our bodies run on—ATP. There is one report of a 76-year-old woman who developed a life-threatening condition (eosinophilic pleuropericardial effusion) while taking 300 mg of pantothenic acid per day and 10 mg of biotin per day.2 However, it is not clear whether the vitamins caused the problem. Are there any drug interactions? Certain medications may interact with pantothenic acid. Refer to the drug interactions safety check for a list of those medications. References:
