Magnesium plays a vital role in muscle and nerve function by acting as a cofactor in over 300 enzymatic reactions in the body. It helps regulate muscle contractions and nerve impulses, and is essential in the production of energy (ATP). Magnesium also aids in maintaining normal heart rhythm and blood pressure. Adequate magnesium levels are crucial for athletic performance, recovery, and overall health. Deficiency may lead to muscle cramps, mental disorders, and cardiovascular issues, emphasizing the importance of this mineral in the diet.
