Sunflower Lecithin has phosphatidyl choline, the most abundant phospholipid in the cell membrane, where it plays a key role in cellular signaling and synaptic function. 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.
