Lecithin is a natural edible oil and important nutrient derived from soybeans that offers many health benefits. One such benefit is its ability to break down fats in the body by regulating the flow of nutrients and waste materials in and out of the cell to ensure that they do not build up in the liver. Lecithin also prevents the build-up of fats and bad cholesterol in the walls of the heart, arteries, and veins, all of which help to promote cardiovascular health. For this reason, Lecithin may be beneficial to those with high cholesterol. Additionally, studies suggest that Lecithin may help improve memory in brain function.
