Because it contains phosphatidylcholines, lecithin is a source of choline, an essential nutrient. Clinical studies have shown benefit in acne, in improving liver function, and in lowering cholesterol
Lecithin, as a food additive, is also a dietary source of several active compounds: Choline and its metabolites are needed for several physiological purposes, including cell membrane signaling and cholinergic neurotransmission
Lecithin is rich source of choline, a vital part of every cell membrane in the body. Without choline, cell membranes would harden, prohibiting the passage of life-sustaining nutrients in and out of the cell. Researchers believe that lecithin and choline provide multiple health benefits: improved cardiovascular health, heightened liver function, optimal reproductive efficiency and fetal development, and enhanced athletic performance.
