Peat Archive

Ray Peat considered magnesium one of the most important minerals for metabolic health, essential for energy production, nerve and muscle function, and cardiovascular health. He noted that magnesium deficiency is extremely common and contributes to hypertension, heart arrhythmias, muscle cramps, anxiety, insomnia, and metabolic dysfunction.

Peat recommended magnesium-rich foods (dark chocolate, epsom salt baths) and topical magnesium for those with digestive issues. He noted that stress depletes magnesium (cortisol promotes urinary magnesium loss), creating a vicious cycle where magnesium deficiency increases stress vulnerability.
