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 biological 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 in your body are almost two-thirds Lecithin. Lecithin is composed of many different components, including Choline, Inositol, Linoleic Acid, Phosphatidylserine, beneficial fatty acids and triglycerides. These valuable constituents of Lecithin are vital for the proper functioning of many metabolic processes.* NOW® Lecithin Granules are dervied entirely from Non-Genetically Engineered (Non-GE) soybeans that have been Identity Preserved (IP).
