Nutritional Health, Herbal and Vitamin Supplements

Choline is a phospholipid (a compound that contains both fatty acids and water-soluble components). Choline is produced in the liver and it is found in the brain. Dietary sources of Choline include animal foods such as beef and eggs, as well as plant foods, particularly soybeans and wheat germ. Choline is a necessary part of human cell membranes, and it is also involved in the movement of cholesterol in the body - possibly helping to keep cholesterol deposits from forming in blood vessels. Additionally, it plays a role in the production of acetylcholine, which is a neurotransmitter required for memory, other brain functions, and muscle control. Neurotransmitters are chemicals that carry signals from nerve cells to other cells.

Based on several studies, possible health benefits of Choline include the prevention and treatment dementia, a serious cognition impairment in the brain. Individuals who suffer from demential many times also have lower than normal levels of a neurotransmitter know as acetycholine, which affects both memory and muscles. It is believed that choline supplementation many improves symptoms associated with dementia by helping the body to increase and maintain levels of acetylcholine. However, no human studies have tested whether choline may actually prevent dementia.

Choline deficiencies may cause the development of liver damage.
