Choline is not generally considered a vitamin, but it is an essential micronutrient. While there is not yet an official Daily Value (recommendations aimed at avoid deficiency states), Adequate Intake (AI) levels for choline were established by the National Academy of Sciences in 1998. Although the human body is capable of synthesizing choline, it is mostly obtained through diet, including consumption of liver, eggs, breast milk and other choline-rich foods. Choline is vital for healthy liver function and normal brain development.
