Essential minerals potassium and magnesium support muscle and nerve health

Essential minerals such as potassium and magnesium play critical roles in various physiological processes, including muscle contraction, nerve signaling, and energy production.

Potassium is vital for maintaining a normal heart rhythm, regulating fluid balance, and facilitating electrical signals between cells. A deficiency, known as hypokalemia, can lead to symptoms such as muscle cramps, fatigue, and weakness. Specialist Joëlle Mawaguia notes that while these symptoms can indicate low potassium, they may also be caused by muscle fatigue or other mineral imbalances.

Magnesium is involved in over 300 physiological processes, including protein synthesis, immune system function, and the maintenance of bones and teeth. According to Dr. María Amaro, magnesium helps regulate blood sugar and blood pressure. Common signs of deficiency include nighttime cramps, sleep disturbances, irritability, and fatigue. Dietary sources to help meet magnesium needs include legumes, nuts, seeds, whole grains, and green vegetables like spinach.
