NOW® Sunflower Lecithin softgels are non-GMO and soy free. They are also a natural source of phosphatidylcholine, which comprises a major portion of our brain and nervous system. In addition, sunflower lecithin is naturally packed with phosphatidyl inositol, phosphatidyl ethanolamine, and is a source of essential fatty acids. Lecithin aids in emulsifying fats, enabling them to be dispersed in water.
