Magnesium: An Invisible Deficiency That Could Be Harming Your Health

By Dr. Joseph Mercola

Magnesium is a mineral used by every organ in your body, especially your heart, muscles, and kidneys.[1] If you suffer from unexplained fatigue or weakness, abnormal heart rhythms or even muscle spasms and eye twitches, low levels of magnesium could be to blame.

If you’ve recently had a blood test, you might assume it would show a magnesium deficiency. But only 1 percent of magnesium in your body is distributed in your blood, making a simple sample of magnesium from a serum magnesium blood test not very useful.

Most magnesium is stored in your bones and organs, where it is used for many biological functions. Yet, it’s quite possible to be deficient and not know it, which is why magnesium deficiency has been dubbed the “invisible deficiency.”
