In July 2019 researchers from Iran published their review of the medical scientific literature to assess the effect of omega-3 and vitamin E supplementation taken together on total cholesterol, triglycerides, LDL(bad)-cholesterol and HDL(good)-cholesterol in individuals with metabolic syndrome. A total of five studies, involving 254 individuals, met the inclusion criteria and were included in the review. Results showed that omega-3 and vitamin E supplementation taken together significantly reduced the triglyceride and LDL(bad)- cholesterol levels in overweight individuals with metabolic syndrome, but had no significant effect on the levels of total cholesterol and HDL(good)-cholesterol.
