The naturally occurring phosphatides in lecithin are precursors for components of cell membranes and the nervous system.

Phosphatidyl Inositol is a major component of cellular membranes. It helps to maintain proper electrical energy and nutrient transfer across the cell membrane.

Phosphatidyl Choline is a precursor of acetylcholine, a stimulatory neurotransmitter. It also helps in the production of lipotropic agents which convert fats into useful products and in the production of hdl (good) cholesterol. Nature's Way lecithin is 100% natural from soy oil.
