Choline is another one of the essential B vitamins and plays a role in the functioning in almost every cell in our bodies. It helps the body transport cholesterol out of the liver and also helps to lower blood levels of homocysteine which, is a risk factor to coronary heart disease. Choline is also a precursor for acetylcholine, one of the neurotransmitters involved in memory.


Some studies conducted on animals have shown that extra amounts of choline can enhance brain development and lead to better memory and attention over an entire lifespan. Generally, folic acid and vitamin B6 are recommending to help lower homocysteine levels and the risk of developing heart disease however, studies have shown that formulas that contain choline have achieved better results since it plays a role in some of the chemical reactions that control the homocysteine levels.

Symptoms of choline deficiency have only been seen in humans who have been fed choline deficient diets; symptoms include fatty liver disease and other liver damage. Since choline deficiencies have only been seen in experimental situations this means choline meets one of the requirements to be an essential nutrient.

Some good sources of choline are shellfish, eggs, poultry, tuna, salmon and collard greens.
