Magnesium as a Bioenergetic Checkpoint Linking Mitochondrial Function, Metabolic Disease, and Aging.
Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing mechanistic literature without systematic search or new primary empirical data.

What was done
The authors synthesized literature concerning renal magnesium handling, mitochondrial magnesium transport, and MgATP biochemistry to propose a conceptual framework positioning magnesium as a bioenergetic checkpoint governing mitochondrial function, metabolic resilience, and aging.
What was found
The abstract reports no quantitative data, statistics, or numerical findings. It outlines a conceptual model in which magnesium availability regulates functional ATP pools, constrains kinase signaling, and limits calcium overload and oxidative stress, while disruptions are linked to insulin resistance, metabolic inflexibility, acute kidney injury, and cellular senescence.
Why it matters
This framework shifts the view of magnesium from a passive electrolyte to an active regulator of mitochondrial bioenergetics and cellular senescence, outlining potential compartment-specific therapeutic targets.
Limits
This is a narrative review providing theoretical synthesis rather than empirical human trial data or a systematic review. Specific treatment protocols, clinical effect sizes, and causative thresholds in humans were not evaluated in the abstract.
