Sunflower lecithin is a fatty substance pressed from sunflower seeds. Manufacturers extract it to work as an emulsifier in foods and supplements. The supplement supplies choline and phospholipids, two materials your body uses to build and maintain cell membranes. Some people take it to support normal cell structure. The organic label simply means the sunflowers were grown under organic farming rules, not that it works differently inside the body.
People typically stir it into food or smoothies once or twice a day, since its thick texture blends well that way. Large servings can upset the stomach and may cause nausea or loose stools.
