Lecithin is a naturally occurring compound found in all cells in nature, plant and animal. It plays a major role in almost all biological processes - including nerve transmission, breathing and energy production. The word Lecithin is taken from the Greek Lekithos, which means "egg yolk". A fitting name for this essential nutrient, for the egg is considered a symbol of life, strength and fertility. Lecithin is important for all of these biolgoical functions and more. 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 different components, including Choline, Inositol, Linoleic Acid, Phosphatidylserine, beneficial fatty acids and triglycerides.
