Vitamins
Vitamins are organic compounds that help regulate fat, CHO and Pro metabolism in the body. They cannot be made by the body and have to be provided by the food we eat. Fortunately we only need tiny amounts of these vitamins. Vitamins are not an energy source, but they play a vital role in releasing the energy stored in the other foods we eat. In addition, our enzyme, nervous, hormonal and immune systems are dependent on vitamins for regulation and control. Because of this, vitamins are essential for good health, well-being and growth.
Vitamins are divided into two types:
- Water-soluble: These vitamins cannot be stored in the body and need to be replaced regularly through our diet
- Fat-soluble: These vitamins are stored in the body and include vitamins A, D, E and K. Although these vitamins can be stored, they should still be part of a healthy diet

Minerals
Minerals are inorganic elements that have many roles in the body's functioning. Apart from their more well-known roles in the formation of strong bones and teeth, they also help to control the nervous system, fluid balance in tissues, muscle contractions, some hormonal functions and enzyme secretion. Minerals are as essential as vitamins and, just like most vitamins, they cannot be made in the body. All our bodies' mineral needs have to be supplied from our diets.
