Lecithin is a fat-like compound found in human cells and is required for proper biological functioning – it’s a good source of the essential nutrient choline.

What are its health benefits?

Lecithin is a fat that is essential in the cells of the body. Lecithin is converted into choline, belonging to the B group of vitamins, which transmits nerve impulses.

Lecithin is used as an emulsifying and stabilising agent in food (for example, margarine and chocolate production) and cosmetics (creams, lipsticks, conditioners). It is taken as a complementary medicine and also used in the manufacturing of medicine.

Lecithin supplements may have the following benefits:

  • As it is a good source of choline, lecithin assists in the management of memory disorders, including dementia and Alzheimer’s disease.
  • It is used as a skin moisturiser and assists in the relief of symptoms associated with eczema.
  • Lecithin assists in the management of gallbladder disease, liver disease and high cholesterol.
  • It aids in the management of depression and anxiety.
