A new study conducted by researchers at Brown University has identified certain supplements that may be beneficial for heart health. The meta-analysis published in the\Journal of the American College of Cardiology reviewed more than 884 studies on 27 types of micronutrient supplements among 883,627 participants and found strong evidence that omega-3 fatty acid, folic\acid and coenzyme Q10 (CoQ10) are micronutrients that reduce cardiovascular risk. Omega-3 fatty acid was found to decrease mortality from cardiovascular disease; folic acid lowered stroke risk; and CoQ10 decreased all-cause mortality. Omega-6 fatty acid, L-arginine, L-citrulline, melatonin, magnesium, vitamin D, zinc, alpha-lipoic acid, catechin, flavanol, curcumin, genistein and quercetin also showed evidence of reducing cardiovascular risk.
