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.
