Potassium is necessary for muscle function as it regulates muscle contractions and nerve signaling. Other minerals like iron, zinc, and phosphorus play supportive roles but do not directly influence muscle contraction. Therefore, maintaining sufficient potassium levels is crucial for optimal muscle performance.
