Supplements for Cardiovascular Disease
8 supplements with research evidence for Cardiovascular Disease
What the Research Shows
Research into supplements for cardiovascular disease shows varying levels of evidence. Magnesium and potassium have the strongest evidence, with higher levels of magnesium and increased potassium intake both being associated with a reduced risk of cardiovascular disease and improved overall heart health. Moderate evidence exists for several other substances. Vitamin B6 is linked to the regulation of homocysteine levels and coronary heart disease risk, while flaxseed has shown potential benefits for endothelial function and risk markers in patients with coronary heart disease. Additionally, studies have explored the roles of creatine in relation to hypertension and the use of specific Rhodiola formulations for treating ischemic heart disease and unstable angina. In contrast, there is weaker evidence for selenium and Vitamin C. Meta-analyses do not currently support the use of selenium for the primary prevention of coronary heart disease. While some observational studies suggest an inverse relationship between Vitamin C and major cardiovascular events, systematic reviews are still evaluating its efficacy for primary prevention.
