Lecithin is a popular supplement, but there are very few sources of non-soy based lecithin as it is typically sourced from soy. Most soy sources are from genetically modified (GM) crops, where as presently, there are no genetically modified crops of sunflowers. NOW Sunflower Lecithin has Phosphatidyl Choline, the most abundant phospholipid in the cell membrane. Although phosphatidylcholine phospholipids are present in almost all cells within the body, the highest concentrations may be found in the brain, heart, liver, and kidneys. NOW Sunflower Lecithin also naturally abounds in Phosphatidyl Inositol, Phosphatidyl Ethanolamine, and essential fatty acids. Lecithin in the diet aids in emulsifying fats, enabling them to be dispersed in water and as a choline-containing phospholipid, its choline is easily absorbed and utilized by the body.
