Nutritional Minerals are kinds of minerals that our bodies need to survive. Sodium, for instance, is a mineral that we usually can get a lot of, usually from salt. However, other minerals such as Manganese, Zinc, Copper, Iron, Potassium, and Phosphorous are other Nutritional Minerals that our bodies need to perform specific functions. We have to understand that not all minerals that are given as supplements are universally agreed to be nutritional. Boron, for example, is not considered nutritional by some parties, yet multivitamins often have trace amounts of Boron added.
