Vitamins are broken up into two categories: fat soluble and water soluble. Fat soluble vitamins are vitamins A,D,E & K. They are found mostly in fatty foods (with some exceptions of course). Water soluble vitamins such as vitamin C and all of the B vitamins are ones you find in fruits, veggies, dairy and grains (again with some exceptions). The difference in these vitamins are that water soluble pass through your body and fat soluble ones are stored for longer use.
