Magnesium, according to Dr. Danine Fruge, Associate Medical Director at the Pritikin Longevity Center in Miami, Florida, “affects everything from your heartbeat to your muscles to your hormones.”
In its early stages, magnesium deficiency shows up as nervous twitches, tingling, numbness and cramping. Note that these are muscle and nerve disorders—areas that magnesium affects the most.
If unchecked, experts at the University of Maryland Medical Center warn that it could result in abnormal heartbeat, seizures and even personality changes.
The recommended daily intake of magnesium is 310 to 320 milligrams for women and 400 to 420 milligrams for men. “Studies have shown that only about 25% of U.S. adults are at or above the recommended daily amount,” says Fruge. In other words, three in every four Americans don’t get enough magnesium.
