Magnesium
topic
Magnesium is an essential mineral serving as a cofactor for over 300 enzymatic reactions — including ATP production, DNA synthesis, protein synthesis, nerve signal transmission, muscle contraction and relaxation, blood pressure regulation, blood glucose control, and the regulation of calcium and potassium balance. It is the fourth most abundant mineral in the body and one of the most commonly deficient, with approximately 50–60% of the US population consuming less than the recommended daily amount (310–420mg) from dietary sources.
Role
Magnesium deficiency is one of the most widespread and most impactful micronutrient insufficiencies in modern populations — and one of the least recognized because serum magnesium levels (the standard clinical test) poorly reflect total body magnesium status, producing normal lab results in people who are functionally depleted at the tissue level. Subclinical magnesium insufficiency is associated with impaired sleep quality, muscle cramps, anxiety, constipation, elevated blood pressure, insulin resistance, migraine, and chronic fatigue — symptoms that are individually treated by dozens of different pharmaceutical interventions when the common nutritional underlying driver is never evaluated.
