Vitamin is not component which constitutes the body's tissues and cells, it also does not produce energy, its main function is to participate in the regulation of metabolism;
Most of the vitamins can’t be synthesized or insufficient synthesized by the body, so they can not meet the needs of the body and must always be obtained through food;
