The Claim

In overweight and obese adults, a 12-week combined supplementation with magnesium and vitamin D does not significantly alter serum parathyroid hormone levels or markers of inflammation compared to vitamin D alone or placebo.

Cause and effect
1 study reviewed
In plain English

Taking magnesium and vitamin D together for 12 weeks did not change blood levels of a calcium-controlling hormone or inflammation markers in overweight or obese adults, compared with taking vitamin D alone or a placebo.

See the scientific wording

In overweight and obese adults, combined supplementation with magnesium and vitamin D for 12 weeks did not significantly affect serum parathyroid hormone levels or markers of inflammation compared to vitamin D alone or placebo, indicating that the supplements did not produce measurable changes in these outcomes in this population.

Why this might work

Taking magnesium and vitamin D together makes more vitamin D in the blood. But this extra vitamin D doesn't change the hormone that controls calcium or the signs of inflammation in overweight and obese people, so there's no difference in these measurements.

  1. Study: The effect of combined magnesium and vitamin D supplementation on vitamin D status, systemic inflammation, and blood pressure: A randomized double-blinded controlled trial.

    The study tested whether taking magnesium and vitamin D together changes parathyroid hormone or inflammation in overweight and obese people, and it found no significant changes, just like the claim says.
