Choline L-Bitartrate is a salt form of choline with L-tartaric acid. Choline benefits cognitive enhancement. It is a precursor of neurotransmitter acetylcholine. It is an important component of all cell membrane. Choline is classified as a water soluble essential nutrient, and usually is grouped the Vitamin B complex. For adult, Adequate Intakes (AI) for this micronutrient between 425 to 550 milligrams daily has been established by the Food and Nutrition Board of the Institute of Medicine of the National Academy of Sciences (USA). Choline supplements are often taken as a form of “smart drug” or nootropic, due to its precursor role of the neurotransmitter acetylcholine. Research suggests that memory, intelligence, and mood are mediated at least in part by acetylcholine metabolism in the brain.
