Which of the following is considered a trace mineral?

Calcium
Iron
Zinc
Magnesium

The correct answer is: Zinc

The correct answer is Zinc because it is classified as a trace mineral, which means that the body requires it in small amounts compared to major minerals. Trace minerals are essential for various bodily functions, including enzyme activity, immune function, and the synthesis of DNA and proteins. Calcium, while crucial for bone health and other functions, is categorized as a major mineral due to the higher amounts needed in the diet. Iron, also a critical mineral, is necessary for oxygen transport in the blood and is sometimes considered in the same context as zinc but plays a larger role in quantity required. Magnesium is another major mineral vital for energy production and muscle function, also needing more significant intake than trace minerals like zinc. Zinc stands out as an essential trace mineral, highlighting its importance in minute quantities that support health and metabolic processes.
