Magnesium is the fourth most abundant mineral in the human body after calcium, potassium, and sodium, according to the study. Foods high in magnesium include green vegetables, egg yolk, soybeans, brown rice, and cashews. The recommended allowance for magnesium for males is 420 mg per day and 320 mg per day for females.

However, the standard diet in the United States contains only approximately 50% of that, meaning as much as half of the total population is magnesium deficient, according to the study. Magnesium status is low in populations who consume processed foods high in fats, refined grains, sugar, and phosphate, according to the study.

Vitamin D cannot be metabolized without sufficient magnesium levels. 😎
