Magnesium has been linked to over 300 enzymatic processes in the human body, so it comes as no surprise that magnesium levels have been linked to a healthy heart. Of course supplements don’t fix everything, but is there a best type of magnesium when it comes to improving the health of our heart?

Magnesium is widley considered to be one of the best supplements for heart health, although there are many different kinds of magnesium on the market. Choosing a supplement that’s bioavailable is key to ensure the correct amount of elemental magnesium is absorbed rather than lost through our intestines. Magnesium oxide for example has poor bioavailability and a laxative effect so should therefore be avoided to improve cardiovascular function.

Having blood pressure that’s too low as a result of a weakened heart rate is no joke, but having high blood pressure also needs to be avoided. Keeping your heart operating at the right level is an important for good health and magnesium, especially in supplement form, plays a big role in this function. When you begin researching which brand is optimal for your body or condition- you’ll realise there’s a great deal of magnesium supplements and products to consider. Here we explore which supplement is most suited for cardiovascular health. 

Why is magnesium good for the heart?

Magnesium is needed to ensure complete relaxation of blood vessels near your heart, which helps to maintain a healthy blood pressure. What’s more, studies have shown, participants that supplemented oral magnesium experienced better supported blood pressure, in comparison to those taking a placebo only. Magnesium was also shown to induce a concentration and smooth muscle cell-dependent dilation which is important for correct heart function. This is why considering a supplement to address magnesium deficiency absolutely essential. 

Which magnesium is best for your heart?

If you’re using a magnesium supplement specifically to address your cardiovascular well-being, you may be better off taking more than one form of magnesium within your supplement.

Whilst it’s known magnesium citrate is a better absorbed magnesium, there are advantages to magnesium glycinate for cardiovascular health, increasing evidence has shown the amino-acid glycine offering protection against heart disease. This particular amino acid has shown the ability to improve the bodies use of nitric oxide, which is an important chemical that increases blood flow, whilst simultaneously lowering blood pressure (1). Demonstrating once again that magnesium was an incredibly important mineral to help heart conditions.

What type of magnesium supplement to take for heart palpitations

In a study to assess magnesium as a supplement the following was observed. In the treatment of cardiac arrhythmias of varying genesis, an “observational study” in 1,160 patients showed that a high-dose oral magnesium preparation (Magnesium-Diasporal N 300 Granulat) was effective. In 82% of the patients observed, a dose of at least 300 mg magnesium/day produced good to very good results. Proving Magnesium-Diasporal to be a very effective supplement in increasing magnesium levels. 

In this instance magnesium diasporal is simply a form of magnesium buffered with citrate, which indicates citrate would be the best type of magnesium for heart problems such as palpitations. This is likely because mag citrate is well absorbed, it’s also believed this form of magnesium is the closest type of magnesium to that used naturally by the body. Magnesium buffered with citrate is a combination of magnesium oxide with citric acid that dissolves easily and appears to be readily absorbed.

In some cases optimising magnesium levels has even shown to completely stop heart palpitations for certain people which gives patients tremendous relief.
