Vitamins are essential substances for the body. They help to build the body and to maintain its functions, such as skeletal development and growth, blood clotting and vision. With a few exceptions, the body is unable to synthesize them. That's why their intake through a balanced diet is essential for the body to function properly and for the prevention of certain diseases.
