How it works
Transform -- cofactor for 300-600+ ATP-dependent enzymes and forms the Mg-ATP complex the body actually uses to make and spend cellular energy
Exchange -- gates calcium and potassium ion channels and blocks the NMDA receptor, shaping nerve and muscle excitability across the membrane
Build -- required cofactor for protein, DNA, and RNA synthesis, and supports bone mineralization alongside calcium and vitamin D
Maintain -- supports normal vascular tone and muscle relaxation; deficiency is linked to higher oxidative stress markers
Regulate -- blunts the blood-pressure and stress-hormone response, and supports normal sleep architecture
Process -- NMDA receptor modulation is implicated in synaptic plasticity, a proposed mechanism behind magnesium-threonate cognition research
Form matters
The same nutrient can be made in very different forms -- and a study done on one form does not automatically apply to another. Methylcobalamin is not cyanocobalamin; magnesium glycinate is not magnesium oxide; a whole-food extract is not the synthetic isolate that was studied. Two things decide whether what is in the bottle behaves like the research: the exact form, and independent lab verification (a Certificate of Analysis) that the form and dose on the label are truly what is inside. Without a COA, you are trusting a label, not the science.
On Magnesium specifically: Magnesium oxide is the least well-absorbed common form and has a pronounced laxative effect; glycinate, citrate, and malate forms are absorbed considerably better and are generally preferred when the goal is mineral repletion rather than bowel regularity.
Across your systems
Magnesium is a cofactor for the enzymes that both activate vitamin D and run the sodium-potassium pump, positioning it as a quiet dependency behind two other minerals' own function rather than a nutrient that only acts on its own.
