vitamin B12 test

Vitamins are nutrients your body needs to function and fight off disease. There are 13 vitamins that are essential to your body working well. Vitamins are present in foods and foodstuffs of plant and animal origin. They can be divided into water soluble vitamins (e.g. vitamin C and the vitamins of the B group) and fat soluble vitamins (e.g. vitamin A, D, E, K). Aside from vitamins K and D, the human body cannot synthetise vitamins. Because of this we need to get them through food or in some cases supplements.
