Efficacy of vitamin and antioxidant supplements in prevention of cardiovascular disease: systematic review and meta-analysis of randomised controlled trials.

Frequent consumption of vitamin and antioxidant supplements may not lower cardiovascular disease risk.

​This objective of this study was to determine the effect of habitual intake of vitamin and antioxidant supplements on cardiovascular disease development risk. Researchers analyzed data and evidence extracted from 50 randomized controlled trials. They found out that regular consumption of vitamin and antioxidant supplements did not reduce the odds of developing cardiovascular disease. The findings of this meta-analysis reveal that supplementation with vitamins and antioxidants may have no significant beneficial effect on cardiovascular disease risk.
