A meta-analysis of more than 884 studies finds omega-3, folic acid and CoQ10 among the micronutrients that reduce risk

 Healthy diets are rich in antioxidants like amino acids, omega-3 fatty acids and vitamin C, but exactly how beneficial these micronutrients are for cardiovascular health has long been controversial. Now a new meta-analysis published in the Journal of the American College of Cardiology provides some clarity.

Researchers systematically reviewed a total of 884 studies available to date on micronutrients taken as dietary supplements and analyzed their data. They identified several micronutrients that do reduce cardiovascular risk—as well as others that offer no benefit or even have a negative effect. More than 883,000 patients were involved in the combined studies.

For the first time, we developed a comprehensive, evidence-based integrative map to characterize and quantify micronutrient supplements’ potential effects on cardiometabolic outcomes,” said Simin Liu, MD ...
