Which minerals are microminerals?

Which minerals are microminerals?

• A. Calcium, phosphorus, potassium
• B. Sodium and potassium
• C. Iron, zinc, manganese, iodine, copper
• D. Magnesium and sulfur

Answer: (C)

Microminerals are trace minerals needed in small amounts—typically less than 100 mg per day. They are essential for specific biological roles, such as iron for hemoglobin and oxygen transport, iodine for thyroid hormone production, zinc and copper for enzyme function and antioxidant activity, and manganese for bone formation and metabolism. The set that includes iron, zinc, manganese, iodine, and copper fits this trace-mineral category. The other options list minerals (like calcium, phosphorus, potassium, sodium, magnesium, and sulfur) that are required in larger amounts and are classified as macrominerals. So the correct group is the one with the trace elements.
