Magnesium status
ATP does not work as ATP — it works as Mg-ATP. That single fact puts magnesium behind every kinase, every synthetase and the whole of energy metabolism. Serum magnesium is a poor status marker because the great majority is intracellular and in bone, which is why deficiency is both common and easily missed.
In depth
A cofactor for over three hundred enzymes, including every reaction that handles ATP. Serum levels are a poor guide — less than 1% of body magnesium is in blood, so a normal result does not exclude depletion.
What drives it
Micronutrient status increases it.
