Question: 1 / 430

Which mineral plays a crucial role in muscle function and is considered a major mineral?

Sodium

Sodium is a major mineral that plays a crucial role in muscle function, particularly in the contraction and relaxation processes of muscles. It helps generate electrical impulses that are essential for muscle contractions by contributing to the action potentials that signal muscle fibers to contract. This mineral also plays a vital role in maintaining fluid balance in the body, which is important for optimal muscle performance and preventing cramping.

While iron, fluoride, and copper are essential minerals for various bodily functions, they do not share the same level of direct involvement in muscle function as sodium does. Iron is primarily known for its role in oxygen transport in the blood, fluoride is associated with bone health and dental care, and copper is involved in energy production and iron metabolism, but none of them directly influence muscle contraction in the way that sodium does.
