Lecithin has many health benefits because of which it is widely used as an important ingredient in dietary supplements and other nutritional products. Lecithin is a natural source of choline, a dietary component that is involved in a diverse array of important biological activities.

Choline-containing phospholipids like those in lecithin are necessary for the formation and maintenance of cell membranes. Studies in animals have shown that dietary choline given early in life may increase long-term spatial memory. As a necessary component for normal liver function, choline is crucial for the formation of lipoproteins.

Lecithin serves as an ingredient in functional foods, and also available as a nutritional supplement, in both fluid and granular forms.
