What is the role of manganese in the body?

Manganese plays a crucial role in supporting bone formation, which is the reason why the selected answer is correct. This trace mineral is involved in the synthesis of bone matrix components, including collagen, a protein that provides structure and strength to bones. Additionally, manganese acts as a cofactor for various enzymes that are important in the processes necessary for bone health, including those involved in antioxidant functions, metabolism, and the formation of connective tissues.

In the context of how this compares to the other options, manganese does not play a direct role in oxygen transport like iron does, nor is it primarily responsible for regulating blood pressure. While certain enzymes involved in digestion may require minerals like manganese, its primary impact is more closely associated with bone integrity and formation. Therefore, the role of manganese in supporting bone formation distinctly highlights its importance in skeletal health.
