Lecithin is a fat-like substance called a phospholipid. It is produced daily by the liver if the diet is adequate. Lecithin is needed by every cell in the body and is a key building block of cell membranes; it maintains cell membrane flexibility. Lecithin protects cells from oxidation and largely comprises the protective sheaths surrounding the nerves in the brain and nervous system. It is composed mostly of B vitamins, phosphoric acid, choline, linoleic acid and inositol. Although it is a fatty substance, it is also a fat emulsifier. Emulsifiers in the body play an important role in fat digestion and circulatory health. Choline is useful for making acetylcholine, an important neurotransmitter.
