Majority of Americans Not Getting Enough Magnesium

Most Not Aware of RDA for Essential Mineral



Jul 21, 2004, 01:00 ET from Purdue

    STAMFORD, Conn., July 21 /PRNewswire/ -- Magnesium is an essential mineral
 of a healthy diet.  It may help to maintain the function of the heart, muscles
 and nervous system.*  However, according to a recent Gallup poll, four out of
 five Americans (80%) are not consuming enough magnesium from diet alone.  That
 number may be even higher among those who have certain medical conditions or
 are taking medications known to deplete magnesium in the body.
     Even when including vitamin and mineral supplements together with diet,
 only about one in three (35%) consume the Recommended Dietary Allowance (RDA)
 or better of magnesium (between 310 - 420 mg/day).  The vast majority of
 respondents (86%) were not aware of the daily requirement of magnesium at all.
     Magnesium is essential for the functioning of more than 300 enzymes.
 Proper magnesium levels help maintain normal heart rhythms.*  It is also
 necessary for normal protein synthesis, carbohydrate metabolism, proper muscle
 function and helps to absorb calcium and potassium.*
     "It's clear that most people aren't aware of the important role that
 magnesium plays in the body. If people are concerned about their magnesium
 levels, they should make sure to discuss medications and health conditions
 with their doctor when evaluating their diet and magnesium supplement
 options," said Barbara Levine, R.D., PhD., Associate Professor of Nutrition in
 Medicine, Weill Medical College of Cornell University-New York Presbyterian
 Hospital.
     The majority of people (53%) surveyed couldn't name a good source of
 magnesium, which include 100% bran cereals, avocados, almonds, milk, pumpkin
 seeds, cashews, cooked spinach, sesame seeds, oatmeal, potatoes (baked, with
 skin) and soy beans.(1)
     The body's stores of magnesium can be depleted by certain illnesses or
 chronic conditions such as extensive bowel resection, intestinal or biliary
 fistulas, pancreatic insufficiency, celiac disease, ulcerative colitis and
 Chron's disease.  Certain medications, such as loop/thiazide diuretics (water
 pills) and digoxin, can also affect magnesium levels.
     Additionally, poorly controlled diabetes may be a risk factor for
 depletion of magnesium stores.  High alcohol intake and chronic or excessive
 vomiting or diarrhea can also deplete magnesium.(2)
     Ensuring enough magnesium through diet or supplements is important -- and
 so is making sure that the mineral is absorbed into the body as intended.
 Supplements containing magnesium chloride, such as Slow-Mag(R), allow the body
 to absorb more magnesium compared to products that contain magnesium oxide.
 Not surprisingly, 86% of the survey respondents didn't know difference between
 magnesium chloride and oxide.
     The Gallup Organization conducted a telephone survey of a nationally
 representative sample of 1,009 American adults 18 years of age or older.
 Interviews were conducted between January 6-31, 2004.  For the results based
 on sample size, the margin of error at 95 percent confidence interval is +/- 3
 percentage points.
     This survey was commissioned by Purdue Products L.P., makers of Slow-
 Mag(R) Tablets.  Slow-Mag(R) Tablets provide 128mg of elemental magnesium plus
 212mg of calcium -- two vital minerals -- in every dose.  Slow-Mag Tablets are
 enteric-coated to help prevent stomach upset, and formulated with magnesium
 chloride for increased absorption versus magnesium oxide.  For more

     Key Findings:
     Gallup Poll Survey on Magnesium Intake and Supplement Usage
 
     Americans increasingly understand the necessity of supplementing their
 diet with both a multi-vitamin and extra amounts of certain vitamins and
 minerals.  However, magnesium is not a mineral that Americans typically think
 of as important to their health.  The awareness level of health conditions
 with associated vitamin deficiency is also low.
 
     General Awareness
 
     -- 56% of respondents listed Vitamin C among "most important" among
        vitamins and minerals
     -- 86% of men and women did not know the daily requirement of magnesium
     -- Percentage of respondents who were aware of health conditions
        associated with vitamin and mineral deficiency:
          Heart disease, including high blood pressure:  47%
          Diabetes:                                      32%
          Osteoporosis:                                  71%
          Migraine headaches:                            29%
          Muscle cramps:                                 62%
 
     Intake of Vitamin and Mineral Supplements
     -- 51% of men and 66% of women take vitamin and mineral supplements daily
     -- 73% of respondents did not know how much magnesium they take daily
     -- It is very likely or somewhat likely that more than half of respondents
        (55%) may not be consuming enough magnesium
     -- Four out of five (80%) respondents are below the RDA of magnesium from
        food intake alone; when evaluating food intake plus supplements, more
        than three out of five (65%) were below the RDA.  Responses, though,
        varied substantially between men and women:
          - 86% of men were below the RDA of magnesium from food intake alone
            and 76% were below the RDA with food plus dietary supplement
          - 76% of women were below the RDA of magnesium from food intake alone
            and 55% were below with the RDA with food plus dietary supplement
 
     Intake of Magnesium Supplements Among Patients with Health Conditions
 
     -- Percentage of those who were getting the RDA or better of magnesium
        from food and supplements with the following conditions:
          - Heart disease                        26% (74% were below the RDA)
          - Diabetes                             40% (60% were below the RDA)
          - Osteoporosis                         35% (65% were below the RDA)
          - Migraine headaches                   42% (58% were below the RDA)
 
     -- 86% of respondents could not tell the difference between magnesium
        chloride vs. magnesium oxide and the benefits associated with either
     -- 53% of respondents could not name a good source of magnesium. Foods
        which are good sources of magnesium include: 100% bran cereals,
        avocados, almonds, milk, pumpkin seeds, cashews, cooked spinach, sesame
        seeds, oatmeal, potatoes and soy beans.  Dietary magnesium supplements
        are also available over-the-counter.
