Minerals are inorganic compounds that are required for the proper composition of body fluids, the formation of blood and bone, the maintenance of body fluids,  the maintenance of a healthy nerve function and the regulation of muscle tone, including those of the cardiovascular system. 

Minerals cannot be manufactured and therefore have to be obtained from out diet which is not always possible. Their nutritional value is every bit as important as vitamins are to the body. Typical examples of minerals which actively participate in enzyme function within the body include magnesium and iron. Both magnesium and iron are involved in numerous bio-chemical processes within the body leading to possible deficiencies and therefore the need for mineral supplements. 

You can obtain your minerals from mineral supplements, vitamin and mineral supplements or from multimineral supplements.
