A basic constituent of lecithin that is found in many plants and animal organs. It is important as a precursor of acetylcholine, as a methyl donor in various metabolic processes, and in lipid metabolism.

A nutrient in the vitamin B complex that the body needs in small amounts to function and stay healthy. Choline helps cells make membranes, make a neurotransmitter (a chemical that helps nerve cells communicate with other cells), and remove fat from the liver. It is found in whole milk, beef liver, eggs, soy foods, and peanuts. Choline is water-soluble (can dissolve in water) and must be taken in every day. Not enough choline can cause diseases of the heart and blood vessels and damage to the liver. A form of choline is being studied in the treatment of some types of cancer and to reduce pain and fever. Choline is also being studied together with vitamin B12 in the prevention and treatment of cancer.

Essential nutrient that is part of the B-complex family of vitamins and is a constituent of lecithin; it is important as a precursor of acetylcholine, as a methyl donor in various metabolic processes, and in lipid metabolism; it also aids in hormone production and is needed for the proper transmission of nerve impulses, liver function and gallbladder regulation.

Water-soluble vitamin that is a precursor for acetylcholine, phospholipids, and the methyl donor betaine. (DRI)
