A review published in The Journal of the American Osteopathic Association found Vitamin D can’t be metabolized without sufficient magnesium levels, meaning Vitamin D remains stored and inactive for as many as 50 percent of Americans.
“People are taking Vitamin D supplements but don’t realize how it gets metabolized. Without magnesium, Vitamin D is not really useful or safe,” says study co-author Mohammed S. Razzaque, MBBS, PhD, a professor of pathology at Lake Erie College of Osteopathic Medicine.
Razzaque explains that consumption of Vitamin D supplements can increase a person’s calcium and phosphate levels even if they remain Vitamin D deficient. The problem is people may suffer from vascular calcification if their magnesium levels aren’t high enough to prevent the complication.
Deficiency in either of these nutrients is reported to be associated with various disorders, including skeletal deformities, cardiovascular diseases, and metabolic syndrome.
Researchers say the magnesium consumption from natural foods has decreased in the past few decades, owing to industrialized agriculture and changes in dietary habits.
