Metabolic HealthMagnesium Controls Cellular Energy and May Slow the Pace of Aging
Most people think of magnesium as a basic mineral needed to keep cells alive. This comprehensive review argues it does far more — acting as a key control point for how mitochondria produce and manage energy. When magnesium levels inside cells fall, the functional pool of ATP shrinks, stress-signaling pathways go haywire, and mitochondria become vulnerable to calcium overload and oxidative damage. Over time, this disruption contributes to insulin resistance, kidney injury, and a lowered threshold for cellular senescence — the state where cells stop dividing but drive inflammation. The authors propose that age-related decline in mitochondrial magnesium may be a hidden clock accelerating aging, and they outline precision strategies to restore it beyond simple supplementation.
