Minerals are inorganic substances that can be found in water, rocks, soil, and occur naturally in non-living things. While minerals do not contain calories or energy, they do support a number of essential biological functions and are absorbed through food and drink. They are vital for the growth of strong muscles, nerves, blood, skin, and teeth. They are additionally necessary for the metabolic processes that turn food into energy. You need larger amounts of macro minerals than trace minerals. Macro minerals include calcium, chloride, magnesium, potassium, phosphorus, sodium, potassium and sulfur.
