As a medical school professor, I've watched patients take vitamin D for years with zero improvement in their blood levels.
Now a Vanderbilt clinical trial explains why: they're missing magnesium.
Key findings:
> Magnesium RAISED vitamin D in people who were deficient
> But LOWERED it in people with excess levels
> It acts as a master regulator - not just a booster
> Up to 80% of Americans don't get enough ...
