Lecithin supplements are a source of fatty acids that play an important role in the brain and body.
Lecithin is a fatty substance called a phospholipid. Sources of lecithin include egg yolks, soybeans, sunflower seeds, spinach, liver and other organ meats and nuts.
Lecithin increases the amount of choline and inositol in the body, which helps promote healthy brain and liver function.
Choline serves as a precursor to the neurotransmitter known as acetylcholine, according to the Linus Pauling Institute. [1] This neurotransmitter is involved in a number of body and brain functions, including memory, sleep and circulation.
Inositol is similar to B vitamins and helps promote health levels of blood pressure and cholesterol in the body. It is also involved in breaking down body fat and supporting healthy skin and hair.
Those who do not get enough choline or inositol through dietary sources can increase their consumption by taking lecithin supplement products.
There are several kinds of lecithin supplements available online and in health and wellness stores. Those who are planning to take these supplements should know what these different options are and understand the differences between them before choosing one.

There have been other studies on lecithin derivatives like phosphatidylcholine and Alpha GPC demonstrating positive effects on memory and cognition. However, it is not known whether lecithin use will produce the same effects.
