Document Summary
The degree to which a nutrient can be absorbed and used by the body is known as bioavailability. Minerals, vitamins, and amino acids are considered to be supplements in the us. Women of childbearing age may bene t from folic acid. Adults with lactose intolerance may bene t from calcium and vitamin d. Women with heavy menstrual periods may bene t from iron. The fat-soluble vitamins are more readily stored in the body than water-soluble vitamins. Taking mineral supplements exceeding standards for mineral needs may accumulate in the body to the extent that signs and symptoms of toxicity occur. A nutrient that yields no energy and is required in small amounts (milligrams or micrograms per day) is a micronutrient. A vitamin is an organic compound needed in small amounts in the diet to help regulate and support chemical reactions and processes in the body. Vitamins a, d, e, and k are fat-soluble.
