Does Magnesium Support Heart Health?

Key Takeaways:

  • As an electrolyte, magnesium plays a role in regulating heart rate.
  • Magnesium helps support heart health, and is available in supplement form or in certain foods.*

Magnesium is important for many of the tasks your body performs each day — from helping to manage occasional stress to supporting bone health.* But does magnesium support heart health? And can it support a healthy heart rate? Let’s take a closer look at the role magnesium plays in heart health, and which magnesium supplement may be right for you. 


What is magnesium and why is it so important?

Magnesium is the fourth most abundant mineral found in the body, and plays a role in more than 300 enzyme systems. 1 2 It is one of seven essential minerals that the body needs to function optimally, and is necessary for energy production, muscle contraction, nerve transmission, blood sugar balancing, and more.*

Magnesium also plays a role in supporting heart health.*3 Let’s take a closer look at exactly how it does that.


Does magnesium help maintain your normal heart rate?

Magnesium is an electrolyte, along with other minerals like calcium, potassium, and sodium. Electrolytes play a big role in nerve and muscle function within your body. They help generate and send electrical signals, called action potentials, which allow our nerves to send messages and our muscles to move.

Because your heart is a muscle, having the right balance of electrolytes in your body is an important part of making sure signals are sent to your heart about how fast or slow it should beat.4

Note: Be sure to contact your healthcare provider if you have concerns about your heart health, or are making changes to your supplement routine. 

To understand exactly how magnesium affects your heart rate, you need to know how your heartbeat works. 


How does magnesium support heart health? 

Your heart is a powerful pump that keeps your blood moving through your body. The sinus node sends electrical signals that travel to the top chambers of the heart first, and then the bottom chambers. 

Before the signal reaches the bottom chambers (ventricles) it must pass a cluster of cells called the atrioventricular (AV) node. Think of the AV node as a traffic cop: it helps to slow the signal to make sure the lower chambers (ventricles) are ready. 

You could also think of the AV node as a conductor of an orchestra, making sure each section of the heart plays its part at the right time to keep your blood flowing smoothly.

Magnesium plays a role in the proper timing of the AV node. Too much magnesium, and your heart may beat more slowly. Too little magnesium, and your heart rate may speed up.5

What is the best time of day to take magnesium?

Taking it consistently is more important than the specific time you take it. Always remember to follow the instructions on the label when taking a magnesium supplement. 


Which foods have magnesium? 

Dark, leafy greens are one of the best sources of magnesium. This is because plants need magnesium in order to grow. In fact, magnesium is a central component of chlorophyll, the molecule responsible for photosynthesis and what makes leafy greens so green.
