Solgar® Soy Lecithin is extracted from soybean seeds of the highest quality. Lecithin is a natural fat molecule that can be found in plants and animals. It is rich in phospholipids, these are components of the structure of cell membranes. Phospholipids help control the passage of nutrients inside and outside of cells. It also participates in the transport of fats and maintains the level of lipids in the circulation in its proper proportion. Lecithin is found in the liver and other viscera, soy and egg yolk and is used in the food industry as a fat emulsifier.
