The master cofactor

Magnesium: everywhere at once

If you support one mineral through food, make it magnesium. It’s a cofactor in 300+ reactions — every reaction that uses ATP (i.e. all energy), plus insulin sensitivity, blood pressure, cholesterol synthesis, vitamin-D activation, and the nervous system.

It’s also commonly low (processed diets, stress, which burns through it), and — crucially — a serum magnesium test underestimates a deficiency, because the body keeps blood levels up by robbing the tissues.

A “normal” serum magnesium doesn’t rule out a shortfall. Judge it by diet, stress and symptoms — cramps, poor sleep, anxiety, sugar cravings.

Magnesium and the B-vitamins power the energy pathway
