Lecithin can be found in foods such as liver, soy, and egg yolk, and is a rich source of B vitamins, especially choline. Although it is a fatty substance, it is used in foods as a fat emulsifier, helping to break down fats such as cholesterol and other lipids, allowing them to disperse in water and be removed from the body.
Lecithin is a source of phospholipids, a functional component of all cells. It supports the structure of cell membranes and is involved in controlling the transport of nutrients into and out of cells. It also plays an important role in the transport of fat found in the bloodstream.
