“It is currently estimated that 60% of adults do not achieve the average dietary intake (ADI) and 45% of Americans are magnesium deficient, a condition associated with disease states like hypertension, diabetes, and neurological disorders, to name a few.”
Only 0.8 percent of the body’s magnesium is in the blood, so the standard blood test can look normal while you run low. That argument is solid. Two of the three authors list their affiliation as Human Nutrition and Pharma at Balchem Corporation. A paper that says half the country is deficient, written by people in the nutrition business, deserves a second opinion.
