Choline
Though it lacks numeric designation, choline (C5H14NO) is usually grouped in the complex of B vitamins. Choline is essential for constructing the body’s cell membranes.
The body can synthesize choline, but not in sufficient quantities to meet bodily needs. Owing to self-synthesis, choline is not strictly a vitamin.
Cauliflower, broccoli, and spinach are high in choline.
