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. NOW® Non-GMO Lecithin Granules are derived entirely from non-genetically modified soybeans that have been Identity Preserved (IP). This guarantees that the soybeans are from seedstock that has been certified as non-GMO.
