Magnesium is an essential mineral crucial for energy production and metabolism. It plays a key role in converting food into energy by activating enzymes involved in various biochemical reactions, including those that produce ATP (adenosine triphosphate). Adequate magnesium levels are necessary for muscle function, nerve transmission, and regulating blood pressure. A deficiency can lead to symptoms such as fatigue, muscle cramps, and impaired metabolic processes, highlighting the importance of maintaining sufficient magnesium intake through diet or supplements.
