It’s hard to miss calcium. Most trusted health resources, along with the ever-present media, extol the virtues of calcium as if it were the only mineral our bodies require for good health. We can thank the American Dairy Council for milking calcium and putting it in the spotlight.
But calcium can’t act alone. It needs magnesium. These two minerals are so critical to many functions in the body that not having enough magnesium—and an excess of calcium—can cause serious health complications.
Consider any movement by the body, for example. Electrical impulses transmit signals to the nerves and brain, and movement occurs. But the conductor for these impulses is calcium which enters the cells through calcium channels operated by magnesium. Once calcium does its work, magnesium helps the body get rid of the calcium before it crystallizes.
If there’s no magnesium to help the body eliminate calcium, then the calcium builds up in the cells. That’s why magnesium is often called nature’s calcium channel blocker.[1,2,3]
Calcium works in the muscles, too, contracting muscle fibers while magnesium relaxes them. Too much calcium and your muscles will begin to twitch, spasm, and even result in convulsions.
The same principle applies to the bronchial tubes. Too much calcium can cause the bronchial tubes to swell, resulting in asthma. And without the muscle-relaxing effects of magnesium, calcium excess can produce spasms in the blood vessels and cramping in the uterus (menstrual pain).
We already know that calcium protects and keeps bones and teeth healthy. But without magnesium, the body cannot:
Clearly, even a mild deficiency in magnesium can radically affect bone health.
Many doctors and drug companies view bone loss as a function of estrogen loss and treat it with estrogen, calcium, and bone-stimulating drugs. Unfortunately, there’s ample evidence in the research literature that shows many nutrients, especially magnesium, help keep bones healthy.
To ensure you get the nutrients you need, consider supplementing.
Calcium & Magnesium
Clearly, focusing on a single nutrient like calcium, to the exclusion of all of the other vitally important nutrients like magnesium, can lead to excess calcium and depleted magnesium—and an invitation for more troubling and serious conditions later on.
So to stay healthy, make sure you take calcium AND magnesium. And stay away from supplements that contain both—they’re usually less absorbed forms that are often quickly excreted before they can do any good.
