What is lecithin?

Lecithin is a fat that can be found in many foods like soybeans and egg yolks. It is also known as Egg Lecithin, Lecitina, Ovolecithin, Soy Lecithin, Soy Phospholipid, Soybean Lecithin, Vegilecithin, Vitellin, Vitelline, and other names.

Lecithin has been used in alternative medicine as a possibly effective aid in treating liver disease.

Lecithin has also been used to treat gallbladder disease, dementia related to Alzheimer's disease, age related loss of memory, and head injuries. However, research has shown that lecithin may not be effective in treating these conditions.

Other uses not proven with research have included high cholesterol, manic-depressive disorder, dermatitis, improvement of athletic performance, Parkinson's disease, stress, insomnia, and other conditions.

It is not certain whether lecithin is effective in treating any medical condition. Medicinal use of this product has not been approved by the FDA. Lecithin should not be used in place of medication prescribed for you by your doctor.

Lecithin is often sold as an herbal supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.

Lecithin may also be used for purposes not listed in this product guide.
