                                Around 31 percent of people in the U.S. may be at risk of being deficient in magnesium, a vital mineral for over 300 enzymatic processes. In severe cases, or when oral supplements are ineffective, intravenous (IV) magnesium is administered directly into the bloodstream to rapidly restore essential functions.
