Lecithin is found in the cell membranes of all plants and animals. It assists in creating permeable cell membranes which allows for the transport of nutrients into the cell and removing wastes from the cell. Lecithin also helps fats stay soluble in the bloodstream by assisting in the breakdown and distribution of fats in the digestive system. Lecithin has a rich source of phosphatidylcholine, phospholipids and choline. All of which are important for a healthy nervous system, the structure and health of cell membranes and maintaining and supporting a healthy fat metabolism.
