September 25 2017. A study reported on September 22, 2017 in Nutrients found a lower incidence of metabolic syndrome among dietary supplement users in Korea. Metabolic syndrome, a cluster of symptoms that include elevations in blood pressure, glucose and triglycerides, low HDL cholesterol levels, and abdominal obesity, is associated with an increased risk of diabetes and cardiovascular disease.
The study included 1,847 supplement users and 4,461 nonusers enrolled in the 2010-2011 Korea National Health and Nutrition Examination Survey. Twenty-four-hour diet recall data was analyzed for antioxidant content. Survey responses provided information concerning the use of supplements. Metabolic syndrome was diagnosed when three or more risk factors were present during health examinations.
There was a 18% lower prevalence of metabolic syndrome in dietary supplement users. Among those whose intake of vitamin A was among the highest one-third of supplement users there was a 28% lower risk of metabolic syndrome compared to nonusers whose intake of the vitamin was among the lowest third.
For supplement users whose vitamin E was among the highest, the risk was 26% lower. Supplement users whose total antioxidant capacity from diet and supplements was among the top third of subjects had a 28% lower risk of metabolic syndrome than nonusers whose total antioxidant capacity was among the lowest.
“In conclusion, 30.8% of antioxidants and 38% of total antioxidant capacity were supplied on average by dietary supplements, suggesting that dietary supplements are quite important sources of antioxidant intake and TAC among Korean adults,” Subeen Kim and colleagues conclude. “A more comprehensive investigation of dietary supplements to clarify the effects on metabolic syndrome is necessary.”
