What was done
This narrative review synthesized evidence regarding the physiological functions of magnesium, global dietary intake patterns, determinants of deficiency (e.g., intensive agriculture soil depletion, food processing, aging), associated chronic disease risks, and potential public health interventions.
What was found
The authors report that approximately 2.4 billion individuals (roughly 31% of the global population) fail to meet recommended magnesium intake levels. In China, 64.4% of adults consume less than the estimated average requirement of 270 mg/day, and substantial proportions of US adults fail to achieve the Recommended Dietary Allowance (420 mg/day for men, 320 mg/day for women).
Why it matters
It highlights dietary magnesium insufficiency as a widespread global public health issue linked to elevated risks for cardiovascular disease, metabolic disorders, bone loss, and neuropsychiatric conditions.
Limits
The abstract describes a non-systematic narrative review without formal search protocols or meta-analytic quantification. The figures reflect dietary intake estimates rather than direct biochemical status assays.
