What are 3 minerals that are important for health

The two kinds of minerals are: macrominerals and trace minerals. Macro means "large" in Greek (and your body needslarger amounts of macrominerals than trace minerals). The macromineral group is made up of calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur.

A trace of something means that there is only a little of it. So even though your body needs trace minerals, it needs just a tiny bit of each one. Scientists aren't even sure how much of these minerals you need each day. Trace minerals includes iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
