Which are classified as minor minerals?

The classification of minerals into major and minor categories typically hinges on the amounts the body requires. Minor minerals, often referred to as trace minerals, are those that are needed in smaller quantities but are nonetheless essential for various physiological functions. Copper and selenium are classified as minor minerals because the body requires them in microgram or milligram amounts, translating to their essential roles in enzyme functions, antioxidant defenses, and maintaining overall health.

Copper is critical for the proper functioning of iron metabolism and the formation of connective tissue, while selenium plays a vital role in thyroid hormone metabolism and in protecting the body from oxidative stress. In contrast, the other mineral combinations listed are generally classified as major minerals or do not fit into the minor mineral category due to the higher quantities needed for good health. Understanding these classifications helps highlight the importance of a balanced diet, ensuring individuals receive both sufficient major and minor minerals for optimal health.
