Lecithin is a naturally occurring compound found in all cells in nature, plant and animal. Our brain is approximately 30% lecithin. The insulating myelin sheaths that protect the brain, spine and thousands of miles of nerves in your body are almost two-thirds lecithin. Even the heart has a high concentration of lecithin. Lecithin is composed of many naturally occurring components, including choline, inositol, linoleic acid, phosphatidyl serine, fatty acids and triglycerides.
