Magnesium: For High Blood Pressure, Heart Health and much more!

One out of every 3 people have high blood pressure. This is a common and very serious health concern, as uncontrolled hypertension can cause heart disease and increase your risk of having a stroke. It’s especially dangerous because it often has no warning signs or symptoms.

Magnesium is at the top of my list of recommendations for patients experiencing high blood pressure. I also recommend it for chronic migraines, restless leg syndrome,  frequent leg cramps, chronic constipation, chronic stress, diabetes and asthma. The research continues to demonstrate it’s importance for optimal health for just about anyone. Much of this research is centered on it’s benefits for cardiovascular disease.

Research clearly shows magnesium may reduce blood pressure in people with hypertension. Numerous epidemiological studies have reported more magnesium, potassium, and calcium may reduce your risk of hypertension.

Researchers recruited 155 people to take part in a double-blinded, placebo-controlled, randomized trial. The subjects were randomly assigned to receive either daily supplements of magnesium oxide or a placebo for 12 weeks. They found significant decreases in both systolic and diastolic blood pressure  in the magnesium group.

A review and meta-analysis published online on May 29, 2013 in the American Journal of Clinical Nutrition adds evidence to a protective effect for magnesium against the risk of cardiovascular disease, including fatal ischemic heart disease. (Del Gobbo)

Harvard researchers selected 16 studies that examined the association between serum magnesium or dietary magnesium with cardiovascular disease, ischemic heart disease and fatal ischemic heart disease. The studies included a total of 313,041 men and women, among whom 11,995 had cardiovascular disease and 7,534 had ischemic heart disease. There were 2,686 fatal ischemic heart disease events in the combined study populations.

The studies found a 30% lower risk of cardiovascular disease in association with each 0.2 micromole per liter increase in the mineral, as well as trends toward lower ischemic heart disease and fatal ischemic heart disease risk. Additionally, there was a 22% lower risk of ischemic heart disease with each 200 mg per day increase in magnesium intake.

Evidence to support the current findings has been provided by studies and trials that revealed improvement in vascular tone and endothelial function, reductions in platelet clotting, elevations in high density lipoprotein (HDL), better glucose balance and a decreased risk of stroke in association with higher levels of magnesium. While circulating levels of the mineral are responsive to supplementation or increased dietary intake, magnesium is under homeostatic regulation and levels may vary according to other factors. Authors Liana C. Del Gobbo and associates note, however, that the current findings support the importance of adequate dietary magnesium, and that magnesium intake by most is well below the recommended daily allowance.


Magnesium Supports Heart Health Because it Helps:

Dilate blood vessels
Prevent spasm in your heart muscle and blood vessel walls
Counteract the action of calcium, which increases spasm
Dissolve blood clots
Dramatically lessen the site of injury and prevent arrhythmia
Act as an antioxidant against the free radicals forming at the site of injury


Signs You Are Lacking Magnesium

Up to 80% of the population is deficient in this important mineral, according to Carolyn Dean, MD, ND, author of The Miracle of Magnesium.

There is no lab test that will give an accurate reading of the magnesium status in your tissues. Only 1% of magnesium in your body is distributed in your blood, making a simple sample of magnesium from a blood test often highly inaccurate. That's why most doctors who rely on blood tests for magnesium, and not magnesium deficiency signs and symptoms and the realization that up to 80% of the population is deficient, will miss an important diagnosis.
With that in mind, some early signs of magnesium deficiency to keep an eye out for include:
       Loss of appetite
        Nausea and vomiting
        Fatigue and weakness
        Constipation
        High blood pressure

    An ongoing magnesium deficiency can lead to:
        Numbness and tingling
        Muscle contractions/twitches and cramps
        Seizures
        Personality changes
        Abnormal heart rhythms
        Coronary spasms

If you suspect you are low in magnesium, the best way to consume this mineral is through organically bound magnesium. Foods high in magnesium include:

Avocados               Leafy green vegetables
Almonds                Halibut/Mackeral
Some beans           Cocoa
Cashews                Pumpkin seeds  
Peas                       Boiled spinach

Supplemental dosages range from 200 to 800 mg daily. If you experience loose stools you should reduce your dosage.

If you are taking medication for high blood pressure. there is no reason you cannot supplement magnesium and in fact, doctors who are up to date on their nutrition will recommend it if you ask them. Show them this article if they are not. You may be able to reduce your dosage on your medication... which is a very good thing as all drugs do have side effects. Magnesium has no risk of side effects unless you take way too much.... which will result in loose stools, so you will know to simply reduce your dosage.

I recommend Drs. Best High Absorption Magnesium, 100 mg each. I take 2 in the am and 2 in the pm daily. You probably should too!
