Magnesium – A Vital but Frequently Overlooked Nutrient
Americans consume more calcium supplements than any other people on earth. And if that’s not enough, additional calcium is added to our cereals, our fruit juices, our crackers, our antacids and many other processed foods. Yet, ironically, the U.S. ranks among the nations with the highest incidence of osteoporosis; a painful and debilitating disease marked by calcium loss and bone deterioration. Are we missing something?
About 40 years ago, doctors began routinely prescribing calcium to many men and almost all women over the age of 40 in order to prevent or stop the progression of osteoporosis. The conventional wisdom was that bone loss is due to calcium deficiency. Yet, after 40 years, it is evident that taking calcium alone does not prevent or even slow the progression of osteoporosis.
Magnesium is actually the key to the body’s proper assimilation and use of calcium. Magnesium helps to regulate calcium in the body and allows the body to use calcium as needed. If we consume too much calcium and without enough magnesium to balance it, the excess calcium is not utilized correctly and actually may become toxic, causing many painful conditions in the body.
Magnesium is responsible for over 350 biochemical reactions, all necessary for proper health. Magnesium plays a vital role in digestion, energy production, muscle contraction and relaxation, bone formation and cell division. In addition, magnesium is a key nutrient in the proper functioning of the heart, kidneys, the adrenals, and the entire nervous system.
Most cal/mag supplements contain a ratio of 2 parts calcium to 1 part magnesium. The logic behind this ratio is based on the relative amounts of these nutrients used in the body every day. But research shows that most people over 30 actually need the reverse ratio. Typically, the body holds onto calcium and either stores it or recycles it again and again. But magnesium is either used up or excreted and must be replenished on a daily basis. So, even though our daily need for calcium is greater, we are much more likely to become deficient in magnesium.
If you suffer from two or more of the following symptoms, you may have a magnesium deficiency:
- insomnia or restless sleep
- muscle tension or spasms
- muscle cramps
- constipation
- headaches
- heart palpitations
- PMS
- calcification of tissues or joints
- nervousness or irritability
I recommend magnesium citrate or malate as the preferred forms. Or magnesium in the form of an amino acid chelate. If you believe you might be deficient in magnesium, I suggest taking magnesium alone (without calcium) for several months. Some manufacturers are now producing these minerals together in a ratio of 1 to 1 which I recommend for the longer term. And remember, if you are taking these minerals in the above forms, you may not need to take as much because you’re absorbing more. The body can only absorb a small amount of these minerals at one time. So, if you plan to take more than 100 mg of magnesium, it’s best to take two or more small doses per day than a large dose all at once. For most people, a modest supplementation in the 200 mg range of magnesium will help to maintain adequate levels, and more important, the correct balance of these important minerals.
