Lecithin

Description

Lecithin is a mixture of fats that are essential to cells in the human body. It can be found in many foods, including soybeans and egg yolks.

In the diet, lecithin is the main source of choline, a nutrient similar to the B vitamins. Lecithin is converted into acetylcholine, a substance that transmits nerve impulses.

People use lecithin for Alzheimer disease and dementia, Parkinson disease, and many other conditions, but there is no good scientific evidence to support these uses.
