Magnesium is not a “superfood”—it’s something far more fundamental. As an essential mineral involved in over 300 enzymatic reactions, it quietly sustains processes most of us never consider: nerve signaling, muscle contraction, bone formation, blood sugar regulation, and cellular energy production. Yet despite its importance, nearly half of adults in developed nations consume less than the recommended daily amount—often without realizing the subtle toll deficiency takes on well-being.
