Why your vitamin D supplements might not be working

A new randomized trial from Vanderbilt-Ingram Cancer Center reveals that magnesium may be the missing key to keeping vitamin D levels in balance. The study found that magnesium raised vitamin D in people who were deficient while dialing it down in those with overly high levels—suggesting a powerful regulating effect. This could help explain why vitamin D supplements don’t work the same way for everyone and why past studies linking vitamin D to cancer and heart disease have produced mixed results.
