Lecithin is a soy bean extract and a unique nutritional supplement that lowers cholesterol in the body and helps break down fat. In addition, it has a positive effect on stress relief and improves memory. The main components of lecithin are fatty acids and choline, which is often classified as a B-group vitamin, and contributes to the promotion of brain activity and memory. Lecithin prevents fat deposits in the liver, thereby protecting liver tissue from fat degeneration.
