Magnesium is amineral that supports over 300 biochemical reactions in the human body [1]. Not only does magnesium support digestion, but it functions to help heart health in kids as well. Let’s review the science-backed benefits of magnesium and its impact on your kiddo’s overall cardiovascular and gut health.

Magnesium and Blood Pressure Regulation:

Research has consistently shown that magnesium plays a crucial role in blood pressure regulation, even in kids [2,3]. Adequate magnesium intake has been linked to a lower risk of hypertension, contributing to overall heart health.

Magnesium's Anti-Inflammatory Benefits

Inflammation is a key factor in the risk for developing heart disease and magnesium has been studied for its anti-inflammatory properties [3]. Taking adequate magnesium daily may contribute to a healthier cardiovascular system in your little ones by reducing the risk for inflammation in the body. 

Magnesium and Cholesterol Management

Magnesium has been associated with improved lipid profiles, including beneficial effects on cholesterol levels [4].  Sufficient magnesium in the body may positively impact cholesterol metabolism, promoting a heart-healthy balance.

Magnesium's Role in Muscle Function, Including the Heart:

The heart is a muscle, and magnesium is essential for proper muscle function, including the heart's rhythmic contractions [5]. Maintaining optimal magnesium levels supports the proper functioning of the heart. 

Magnesium for Stress Management

Stress can impact both digestive and heart health in kids. Magnesium has been linked to stress reduction and relaxation by modulating the nervous system [6].  A balanced intake of magnesium may help create a calmer environment to reduce stress and its impact on digestion and heart health.
