Feel the Rhythm-Minerals for Heart Health—Part 2

Cardiac muscle or heart muscle makes up the bulk of the heart's mass. It is one of the body's three muscle groups: skeletal, smooth and cardiac muscle. Cardiac muscle is an extremely specialized form of muscle that pumps blood throughout the body. Cardiac muscle is only found in the heart.
 
Proper heart rhythm is reliant on the adequate dietary intake of four minerals: calcium, magnesium, potassium and sodium. Calcium and magnesium work together to control muscle contraction. While magnesium plays a significant role in heart health, a large part of the population is deficient in magnesium, and would benefit from supplementation to support heart health.

Magnesium's Role in Heart Health

The heart has the highest magnesium requirement of any organ in the human body, especially the left ventricle. Magnesium is important for coordinating the activity of the cardiac muscles (myocytes). It has been shown that low magnesium increases one's risk for cardiac arrhythmias and heart palpitations. Magnesium deficiency can reduce the pump activity, resulting in a partial depolarization and changes in the activity of many potential-dependent membrane channels(1). Magnesium has been reported to increase the sinus node recovery time, atrioventricular node (AVN) conduction time during sinus rhythm, atrial paced cycle length, AV node refractory period and effective refractory period(2). This allows the heart to relax longer and allow for more effective refilling. Low magnesium levels have been seen to result in a variety of cardiac arrhythmias, such as atrial fibrillation and atrial flutter. Magnesium's electrophysiological actions have been shown to help prevent premature ventricular contractions.

Balchem's Albion minerals provide a highly bioavailable form of magnesium called Magnesium Bisglycinate Chelate. Supplementing the diet with Albion minerals can help to ensure that an adequate amount of magnesium is being absorbed and utilized by the body. Look for supplements containing this form of magnesium.
