Just like there are different categories for vitamins, there are different categories for minerals. Some minerals are labeled as macro minerals, while some are labeled as trace minerals. The difference between the two is extremely simple and shouldn’t cause any confusion. Macrominerals are minerals that your body needs in larger amounts, while trace minerals are minerals that your body needs in smaller amounts. When you look at your supplement facts, you’ll find higher dosages (mg) of macrominerals and smaller dosages (mcg) of trace minerals. Macrominerals include calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur. Trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.
