What is it?

Lecithin is found in all living cells. The highest amount of lecithin is found in the brain, heart, liver, and kidney. Lecithin can also be prepared from soybeans. It is commonly used as a supplement for atherosclerosis (hardening and narrowing of the arteries), Alzheimer's disease, depression, dementia, gallbladder disease, gallstones, liver disease, headache, multiple sclerosis, acne (pimples), psoriasis, and high cholesterol. Its use in the treatment of depression, dementia, gallbladder disease, headache, multiple sclerosis, and psoriasis may not be effective. Lecithin that is available at health food stores is usually a combination of fats (including phosphatidylcholine), oil, and carbohydrates.

Other names for lecithin include: phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol, PC-55, ethanolamine, and serine.
