Review: Magnesium May Link Cell Energy, Diabetes and Aging
Graded Preliminary — a review without a systematic search or new data, combining mostly lab and observational findings into a theoretical model.

Magnesium helps control how much energy a cell can use, while its role in aging remains a proposed idea.
Magnesium is usually seen as a basic mineral that cells simply need to survive. A review in the journal Aging Cell argues for a bigger role. The authors describe magnesium as a kind of checkpoint for the cell's energy supply. It takes part in more than 600 chemical reactions. It also helps decide how much of the energy molecule ATP a cell can actually use.
The authors pulled together earlier research rather than running a new experiment. In their model, magnesium protects the cell's power plants, the mitochondria, from calcium overload and damage by reactive oxygen. Low blood magnesium is common in type 2 diabetes, affecting roughly one in three people in observational data. Pooled trials where treatment was chosen at random point to modest gains in blood sugar and insulin with magnesium. In people who already have diabetes, it did not consistently improve how well insulin works. In lab dishes, human connective tissue cells aged faster when magnesium was restricted.
The authors call their aging model a theoretical synthesis. Long-term studies still have to show whether magnesium inside mitochondria drives aging. Blood tests also give only a limited picture of how much magnesium sits inside cells.
