Choline bitartrate is an ester of tartaric acid and choline – an essential nutrient in our daily diet whose presence is critical for the proper functioning of the nervous system. Choline is a precursor for the neurotransmitter acetylcholine as well as phosphatidylcholine and sphingomyelin- phospholipids building the cell membrane of all cells. Because of the fact that choline is synthesized by the body only to a small degree, Choline bitartrate is considered to be a vitamin-like substance, whose endogeneous production is not sufficient. This means that choline must be supplemented to the body through outside sources, and fortunately can be found in many different kinds of food, such as meat, eggs, soy, califlour, spinach, salads and nuts. Choline insufficiency is connected to many different health problems on the part of the nervous and muscle system, as well as problems with the liver and kidneys. Choline plays an important role in the early fetal development process of neural tube closure. Additionally, it has been shown that an insufficiency of this substance has an effect on later phases of nervous system development and is connected to permanent changes within the hippocampus- a structure in the brain of critical importance for processes related to memory. Choline acts as a methyl donor in the reaction of methylation of homocysteine to methionine. It has been shown that supplementation with choline-containing compounds leads to normalized levels of homocysteine in the blood plasma, therefore, it is considered that they can reduce the risk of cardiovascular disease.
