Magnesium and Heart Health

Is magnesium the new miracle worker for heart health? It may be, according to a growing body of research.

Magnesium works to maintain electrolyte balance, vascular tone and structure, and a long list of biochemical and physiological processes required for your heart to function, but here’s where magnesium’s link to heart disease gets interesting: studies are finding it plays a critical role in preventing the most common — and even the most deadly — cardiovascular-related health conditions.

In fact, one decade-long study concluded magnesium deficiency may be more detrimental to cardiovascular health than both cholesterol and saturated fat. And not just one but multiple studies have found the risk factors most commonly associated with cardiovascular disease — including low HDL cholesterol (also known as “good” cholesterol), high LDL cholesterol (“bad” cholesterol), metabolic syndrome, arrhythmia, and high blood pressure — are all linked to low magnesium levels in the body.

Let’s take a closer look at a couple of key ways magnesium works for your heart:

Magnesium And Your Heart

One critical way magnesium works to keep your heart functioning is through the sodium-potassium pump — an enzyme that generates electrical impulses throughout the body, playing a key role in your heart’s ability to beat. Magnesium is actually required to activate the sodium-potassium pump, making it a crucial component in your heart’s electrical system.

More noteworthy, perhaps, is magnesium’s naturally competitive relationship with calcium — a relationship that stimulates movement between the two minerals to generate the heart. Calcium stimulates the muscle cells in the heart to contract, while magnesium takes the opposite step of relaxing those cells. This dance between contraction and relaxation is critical in keeping your heart beating. However, without an adequate amount of magnesium to usher calcium back out of the cells, calcium takes over and leads to overstimulation of the muscle cells, which can then lead to angina and even heart attack.

Magnesium Supplementation in Heart Disease Prevention

More and more studies are finding an association between cardiovascular disease and low magnesium levels, and many have concluded that ensuring adequate magnesium intake is a good preventative measure when addressing heart health.

Regular Heart Beat:

There is a definite link between low magnesium levels and one of the most common heart disorders, known as atrial fibrillation (a type of arrhythmia). Atrial fibrillation occurs when a malfunction in the heart's electrical system — where magnesium plays a critical role — causes the upper chambers of the heart to quiver, resulting in an irregular heartbeat. But here’s where magnesium supplementation can help: Recent research has found that heart arrhythmia — and even sudden death related to arrhythmia — may be preventable with adequate magnesium intake.

Blood Pressure:

Magnesium reduces blood pressure by relaxing the blood vessels and preventing them from constricting, thereby improving overall blood flow. And here’s where this good news becomes great news: Recent studies have found magnesium supplementation works very well to reduce high blood pressure in those who suffer from insulin resistance, prediabetes, and other chronic diseases often linked to cardiovascular disease.


An increase in dietary magnesium is particularly beneficial for those who suffer from chest pain, as magnesium deficiency has been found to be one of the leading causes of angina. In fact, magnesium supplementation is proven to significantly reduce coronary vasospasm, thus reducing chest pain.


People with low magnesium levels are at a higher risk for spasm of the coronary arteries, which is linked with angina and even heart attack. But here’s the kicker: These effects are more pronounced during times of stress. Magnesium not only works to help regulate the body’s stress hormones, adrenaline and cortisol, it also aids the body’s cells in fending off stress, leading to a healthier heart.


Magnesium plays a role in blood sugar regulation, and a growing body of research suggests low magnesium intake is a contributing factor in prediabetes and both Type 1 and Type 2 diabetes. To further complicate the situation, people with insulin resistance tend to lose magnesium through urinary output, thus increasing the likelihood of magnesium deficiency. There are promising signs that magnesium supplementation may reduce the severity of Type 2 diabetes by increasing insulin sensitivity, and it may play a preventative role in prediabetes.

MAG365BF + Your Heart

We created MAG365BF as an ionic magnesium supplement with cofactors for healthy bones, but these cofactors are also critical for heart health. Excessive calcium in the body has been linked to an increased risk for cardiovascular disease, along with other serious health conditions. This is because, when calcium is consumed — especially in excess — it begins to collect in the organs and arteries. This is why the cofactors in MAG365BF are critical not only to bone health, but to our heart health: they work together to direct calcium to where it needs to go in the body, such as the bones and teeth, while preventing buildup in dangerous places, including the arteries and heart. But MAG365BF’s benefits for heart health don’t end there: the cofactors in our formula — including vitamins C, D & K, potassium, boron, and zinc — each hold their own weight in preventing heart disease, making it a well-rounded supplement for the promotion of overall heart health.
