7 Reasons to Get More Magnesium

May 16, 2015 Updated: May 16, 2015

Magnesium is the fourth most abundant mineral in your body.  But few people fully appreciate this miraculous mineral. 

The human genome project reveals that 3,751 human proteins have binding sites for magnesium.  And so far we know this one essential mineral activates over 350 biochemical processes in the body to keep things flowing. 

Here are just seven good reasons to get more magnesium today.

1. Prevent Migraines.

According to University of Vermont Professor of Neurology and migraine expert Robert Shapiro, M.D., Ph.D., every year nearly one in five Americans experience some form of migraine attack.  One in 25 will have headaches lasting at least 15 days per month. These disabling attacks include severe one-sided, throbbing headaches, and sensitivity to light and sound.  They may also involve nasal congestion, cloudy thinking, and nausea.

In one study of 133 migraine patients, supplementing with 500 mg of magnesium oxide for just 12 weeks significantly improved the frequency and severity of migraines.

And a double blind, placebo controlled study from Kaiser Permanente showed that supplementing with magnesium significantly cut the number of days children suffered with a migraine.

2. Lower Heart Disease Mortality.  

A study in the journal Atherosclerosis found that people with low magnesium levels were more than twice as likely to die of heart disease.  They were also more than seven times as likely to die from all causes.

3. Manage Diabetes.  

Magnesium deficiency is common among type 2 diabetics, especially those with neuropathy or coronary disease.  A Harvard study found that diabetics taking 320 mg of magnesium for up to 16 weeks significantly improved their fasting blood sugar levels as well as their HDL (good) cholesterol.

4. Relieve Symptoms of Fibromyalgia.

A double blind, placebo controlled study from the University of Texas showed that magnesium malate improves pain and tenderness in fibromyalgia patients.

5. Lower Risk of Colon Cancer.

Epidemiologic studies link low magnesium levels with higher rates of colorectal cancer.  And a meta-analysis from China confirms that higher magnesium intakes are associated with a lower risk of colorectal cancer and especially colon cancer.

The Chinese researchers analyzed eight prospective studies covering 338,979 participants. Their results, published in the European Journal of Clinical Nutrition, found the highest average intake of magnesium was associated with an 11% reduction in colorectal cancer risk compared to the lowest average intake.  

In addition, for every 50 mg per day increase in magnesium, colon cancer was reduced by 7%.

An earlier meta-analysis by Imperial College London and Wageningen University found that for every 100 mg increase in magnesium, colorectal cancer decreased by 13%.

6. Build Strong Bones.

Studies find a significant association between bone density and magnesium levels. But magnesium content of bones decreases with age. In addition, sugar and alcohol cause magnesium to be lost through the urine.

Magnesium assists calcium in building bone strength, but it does much more.  It stimulates the hormone calcitonin.  That helps draw calcium out of the blood and soft tissues and put it back into the bones. Too much calcium in the blood and tissues can increase the risk of arthritis, heart attack, and kidney stones, as well as osteoporosis.

And getting more magnesium may mean you need less than the government’s recommended 1,200 mg of calcium per day.  One study in the American Journal of Clinical Nutrition found that increasing magnesium while lowering calcium to 500 mg per day was enough to increase bone density.

7. Reduce Signs of Metabolic Syndrome

Mexican researchers looked at the effects of taking oral magnesium supplements on people they categorized as “metabolically obese, normal-weight (MONW) individuals.”

MONW individuals have a body mass index under 25 which is considered normal weight.  But they also have hyperinsulinemia and or insulin resistance.  And they have high triglycerides and high blood pressure.  As a result, these individuals are at higher risk of developing cardiovascular disease and diabetes. 

The researchers studied 47 MONW individuals who had low magnesium levels.  In a randomized double-blind placebo-controlled trial one group received a daily solution of 30 ml of magnesium (equivalent to 382 mg).  The control group received 30 ml of a placebo solution. 

Their results were published in the Archives of Medical Research.  After only 4 months, markers of metabolic syndrome were significantly lower in the magnesium group.  They lowered their systolic pressure by 2.1 points and their diastolic pressure by 3.8 points.  Their fasting blood glucose levels dropped 12.3 points and their triglycerides plunged 47.4%.   

Magnesium is also known to:

  • steady heart rhythm
  • promote normal blood pressure
  • reduce stroke risk
  • help maintain normal muscle and nerve function
  • prevent gallstone disease  
  • support a healthy immune system
  • improve symptoms of autism
  • regulate blood sugar and reduce diabetes risk
  • keep your memory strong
  • improves hearing
  • reduce symptoms of premenstrual syndrome
  • improves asthma symptoms

Symptoms of magnesium deficiency include constipation and other digestive problems, low energy, and irregularities in menstrual flow and reproductive health, and migraine headaches
