Lecithin is found in many foods such as ice cream, milk shakes and chocolates. As a natural emulsifier, it helps to keep fats and water from separating to produce smoothness.
Lecithin is also found naturally in foods and is especially high in egg yolks. The phospholipid is an integral component of cell membranes and is also synthesized to accompany excretion of bile and enzymes in the small intestine.
Dietary lecithin is good for you because it’s completely metabolized and provides the main source of choline in the diet. Choline is a precursor for acetylcholine, a neurotransmitters in the brain, and is vital for proper metabolism of fats in the liver.
For these reasons, you may see lecithin available as a supplement in natural health stores.
Commercial lecithin is derived from soya and sunflower oils. Isagenix products use soy lecithin because of its ease of application. It is only used if ultra-purified to be free of proteins or contaminants.
Note: Although the lecithin is derived from soya oil, it does not contribute any amount of soy protein or soy isoflavones (phytoestrogens). These are eliminated through purification of the lecithin and should not present a concern to those needing to avoid them.
Lecithin is used in place of other emulsifiers—such as chemical emulsifiers—for its healthful nature in IsaLean Shake, IsaDelight and IsaFruits. Isagenix uses only lecithin derived from non-GMO soybeans.
