Which vitamins are not stored in body fat, and why?

Water-soluble vitamins (which dissolve in water), such as vitamin C and the B vitamins, are not stored in the body and must be replaced every day.

Small amounts of vitamin A, vitamin D, vitamin E and vitamin K are needed to maintain good health. Fat-soluble vitamins will not be lost when the foods that contain them are cooked. The body does not need these vitamins every day and stores them in the liver and adipose (fat) tissue when not used.
