Does Zinc Deplete Magnesium?

While the two minerals work synergistically, research shows that taking too much zinc, or about 50 milligrams per day, can decrease the amount of magnesium you absorb and negatively affect magnesium balance.

Does zinc affect magnesium absorption?

Magnesium assists your body in regulating zinc levels, but high intakes of zinc can be detrimental to magnesium absorption – only abnormally high doses (around 142 mg of zinc per day) will reduce magnesium absorption.

Does zinc cause magnesium deficiency?

As a moderately high intake of zinc decreased magnesium balance, further study of the possibility that a high intake of zinc is a health concern for individuals consuming less than the recommended amounts of magnesium is warranted.
