Macromineral
From Wikipedia, the free encyclopedia
Macrominerals (also known as macroelements or bulk minerals) are micronutrients that are chemical elements. They include calcium, magnesium, sodium, potassium, and phosphorus. They are dietary minerals needed by the human body in high quantities (generally more than 100 mg/day) as opposed to microminerals (trace elements) which are only required in very small amounts.
