The Claim
Some people believe that magnesium supplements can completely resolve heart health issues, including high blood pressure and cholesterol problems. This stems from associations made between magnesium intake and cardiovascular health.
Origin
Media articles often highlight the heart-health benefits of magnesium without discussing the complexity of heart disease.
What Science Says
While evidence suggests that magnesium plays a role in heart health, such as regulating blood pressure, it is not a panacea. RCTs show that supplementation can have a modest effect on blood pressure (average reduction of 2-4 mmHg), but it should be combined with other lifestyle changes for optimal heart health.
Verdict
Misleading
