The body deems thirteen vitamins indispensable, and each has a clear job: vitamin A for vision, vitamin C for the immune system, vitamin D for bones, vitamin K for clotting, and the B vitamins to drive metabolism. Here you learn, for each one: what is it responsible for? Good to know: Vitamin A is chemically retinol and fat-soluble, and a deficiency causes night blindness. Vitamin B1 is found in whole grains and legumes, and its deficiency causes the disease beriberi. Vitamin B2 is plentiful in milk and eggs and in excess turns urine bright yellow. The body can make some vitamin B3 itself; a deficiency causes pellagra. Vitamin B5 is found in almost all foods, and ‘pantothen’ means ‘from everywhere’. Vitamin B6, from meat, fish and whole grains, helps build the messengers of the nervous system. Vitamin B7 is also called vitamin H, and vitamin B9, folic acid, is crucial for the development of the neural tube, which is why it is often recommended in pregnancy. Vitamin B12, finally, is found almost only in animal foods, so vegans need to supplement it. Vitamin C, found in citrus fruit and peppers, prevents scurvy.
