All cells throughout the human body are enveloped by membrane composed chiefly of essential fatty acids in the form of compounds known as "phospholipids." The major phospholipid of the human body is phosphatidylcholine. Commercially available phosphatidylcholine preparations are derived from soy lecithin. The beneficial effects are likely due primarily to the essential fatty acid components of phosphatidylcholine and lecithin preparations.
Many find it calming and relaxing for the nerves. As essential nutrient, choline is a building block in cell membranes and is involved in many processes, including the transport of fat from the liver to the blood stream and overall liver function. It takes part in a variety of biochemical reactions that generate single carbon units called methyl groups that, in turn, are important in the synthesis and repair of DNA and the use of vitamin B12, folic acid, the amino acid methionine and the antioxidant "protector" glutathione. Therefore, a deficiency of choline can affect many body functions.
Phosphatidylcholine, a source of choline, supports healthy brain and nerve function as a precursor to neurotransmitter acetylcholine
