Quick Answer. Macrominerals are inorganic nutrients that the human body requires in large quantities because they carry out several critical bodily functions. The most important macrominerals include potassium, calcium, magnesium, sodium, chloride, sulfur and phosphorus.

They are part of the micronutrient family (a group of nutrients which includes vitamins and minerals). Micronutrients are distinguished from macronutrients because they contain no calories and are required in much smaller amounts.
