Nutrient Short List NUTRIENT NAME, DESCRIPTION, SOURCES Biotin Biotin is a coenzyme required for synthesis of fat, glycogen, and amino acids. Deficiencies, though rare, are associated with hair loss, dry skin, and cracks in the corners of the mouth. Liver is a significant source of biotin with smaller amounts found in fruits and meats. Knowledge is limited concerning possible adverse effects of supplementing the diet with biotin although none have been reported in humans or animals . Adult age 19-50 yr-Adequate Intake F/M 30 μ g/d Choline Due to the body’s ability to make its own supply during most of the life cycle, a dietary source of choline is not necessary. A precursor for acetylcholine and phospholipids, choline is found in milk, liver, eggs and peanuts. Supplement with caution as excess choline causes a fishy body odor accompanied by sweating and hypotension. Adult age 19-50 yr-Adequate Intake F 425 mg/d, M 550 mg/d Folate Folate, also know as folacin or folic acid, is important to the formation of DNA and the maturation of red blood cells. As maternal deficiencies are associated with increase risk of neural tube defects in children, women capable of becoming pregnant should be particularly concerned about adequacy. Enriched cereal grains, dark leafy vegetables, enriched bread products, and fortified breakfast cereals are common sources of folate. Although excesses can masks symptoms of vitamin B 12 deficiency, no adverse effects from folate supplementation have been reported. Adult age 19-50 yr-RDA F/M 400 μ g/d Niacin Involved in biological reduction and oxidation reactions, niacin is required for energy metabolism. A niacin deficiency is known as pellagra which is characterized by diarrhea, dermatitis, and dementia and, if untreated, death. The body has the ability to convert tryptophan to niacin, so both must be lacking for a deficiency to develop. Typical sources include meat, fish, poultry, and enriched grains, breads, and breakfast cereals. Niacin supplements used to treat hypercholesterolemia can have side effects, such a flushing of the face and gastrointestinal discomfort. Adult age 19-50 yr-RDA F 14 mg/d, M 16 mg/d Pantothenic acid Pantothenic acid is a component in coenzyme A, which is involved in fatty acid metabolism. It is widely dispersed in many different foods and deficiencies are rare. Common dietary sources include chicken, beef, potatoes, oats, cereals, tomato products, egg yolk, and whole grains. Adult age 19-50 yr-Adequate Intake 5 mg/d Riboflavin Also know as vitamin B 2, riboflavin is a coenzyme in energy production reactions and conversion of certain vitamins to the active form. Mild deficiency increases risk of cancer, cardiac disease, and diabetes mellitus. A more serious deficiency impairs cell replacement which results in dermatitis and cracked lips. Riboflavin is found in milk, as well as in enriched grains, bread products, and cereals. Adult age 19-50 yr-RDA F 1.1 mg/d, M 1.3 mg/d Nutrient Description with Sources
