Lecithin is a natural emulsifier found in many foods. It is often found in foods such as mayonnaise (mixture of fat and water-soluble substance) where eggs which contain lecithin act as an emulsifying agent to keep them mixed together rather than separated such as what happens in a mixture of oil and vinegar due to a lack of an emulsifier like lecithin. Our lecithin is derived from soybeans. Lecithin from soy is an excellent source of phospholipids. These compounds play important structural and functional roles in the cell, particularly the cell membrane. About 60% of the dry weight of the brain is composed of phospholipids, hence their importance in brain structure and function.
As part of the structure of brain cell membranes, phospholipids help support neurotransmitter and hormone function, as they provide the environment that cells need for cell to cell communication and overall cell function. Phosphatidylcholine is a good source of choline, which is needed to support neurotransmitter production, essential for the normal, healthy functioning of the nervous system. Lecithin has also been studied for its role in helping to support healthy cholesterol metabolism, fat digestion and metabolism, thereby providing support for healthy cholesterol levels.
