Vitamins and Supplements Recommendations

1. Vitamin supplementation in patients with specific vitamin deficiencies may be considered for patients undergoing CABG, but the effectiveness is not well established (Class IIb; Level of Evidence C).
2. Supplementation with omega-3 fatty acids and antioxidant vitamins may be considered to prevent postoperative AF after CABG, but additional clinical studies are warranted before routine use of antioxidant vitamins can be recommended (Class IIb; Level of Evidence A).
