Magnesium for Heart Health

Studies have shown than more than half the population of all developed countries are deficient in Magnesium. Somewhere in this fact lays the link between the developed world and heart disease. It makes sense and magnesium, as the fourth most abundant nutrient in the body is especially important for heart health.

What does magnesium do?

Magnesium is a vital mineral that is responsible for many biochemical reactions throughout the human body that keep us functioning and alive. It is a powerful element that keeps muscles working, bones strong and nerves reacting as they need to. One thing that many do not know is that magnesium is responsible for keeping your heart beating as regularly as it does and thus also helping to maintain optimal blood pressure.

To maintain a healthy heart beat and rhythm magnesium is extremely important. Magnesium in the body plays a role in the transport system that carries electrolytes into the various cells. Electrolytes are also vital for managing how nerves and nerve endings work around the heart muscles and how they contract and expand. Without magnesium the heart would stop beating because the nerves that power it are starved of their energy.

Magnesium Research

While it is known there are many heart health benefits that are a result of optimal magnesium levels, more research is still needed. It is known that irregular heart beats are often a result of magnesium deficiencies but studies have yet to fully explain how much or how little is actually required to cause this and overcome it. It seems that everyone has a slightly different requirement in terms of magnesium levels.

Magnesium research is showing results in various areas that are linked to good heart health. For example, studies are showing that magnesium supplements can lower blood pressure thus taking pressure off the heart. Likewise, magnesium is known to relax and calm the body and supplementing can reduce stress and subsequent pressures on the heart. Studies have shown a definite link between hypertension and low magnesium levels.

How much magnesium for a healthier heart?

The amount of magnesium you need varies from person to person with age, gender, size and lifestyle being the most common differentiators. As a healthy adult you should have around 25 grams of magnesium stored in your body, most of this is found in your bones. The recommended daily allowance varies between 400 milligrams to men to just over 300 milligrams for women but as get older the RDA does increase very slightly.  Unfortunately, the RDA is very general and not a great indicator for optimal levels. A simple blood test will show if you are magnesium deficient or not.

As always, when considering any form of supplement, especially for heart health matters, it is always worthwhile consulting a professional medical practitioner. There can be cases of Magnesium overdose and Magnesium is not some miracle cure for heart problems.
