Minerals are nutrients your body uses to build bones, carry oxygen and keep muscles and nerves working normally.† This department covers magnesium, zinc, calcium, iron, potassium, selenium, iodine, trace minerals and electrolytes, in single-mineral and combination formulas.
What to look for on the label
The Supplement Facts panel lists the amount of the mineral itself, often called elemental, with the compound in parentheses, for example "Magnesium (as magnesium glycinate) 200 mg." Forms differ in how much mineral each tablet holds and how they sit with your stomach. Your body absorbs calcium most efficiently in amounts of 500 mg or less at a time.
Good to know
Iron-containing products carry an FDA-required warning because accidental overdose of iron is a leading cause of fatal poisoning in children under 6, so store them out of reach. Supplemental magnesium above 350 mg a day can upset digestion, and people with kidney disease should talk to their doctor first.

Frequently asked questions
Which form of magnesium should I choose?
Forms differ in magnesium per tablet and in how they sit with your stomach; oxide is among the forms most often linked to loose stools. Compare the elemental amount on the label.
Should I take calcium and iron together?
Calcium may reduce iron absorption, so many people take them at different times of day.
Why do potassium supplements contain so little potassium?
Most over-the-counter potassium supplements provide no more than 99 mg per serving. Ask your doctor before taking more, especially if you take medication or have kidney disease.
