Magnesium is an essential micronutrient that serves as a cofactor in over 300 enzymatic reactions. It supports critical processes like energy production, DNA synthesis, and muscle and nerve function. All of these pathways are vital for overall health and preventing chronic conditions. Despite its importance, up to 50% of U.S. adults may be deficient in magnesium. This leads to symptoms such as fatigue, insomnia, and muscle cramps, as well as more serious health issues.
