Abstract

Metabolic syndrome (MetS) is a global challenge for atherosclerosis. It was hypothesized that a four-week consumption of anthocyanin supplements by MetS patients who had three or more risk factors linked with metabolic syndrome would have a greater improvement in cardiometabolic biomarkers and would also reduce the risk of thrombosis. A total of 55 participants in two groups of Normal healthy and MetS (age 25-75y) were given 320 mg anthocyanin supplements twice daily for 4 weeks. Platelet coagulant activities, lipid profiles, fasting blood glucose, and inflammatory and oxidative stress biomarkers were measured before and after supplementation to evaluate the atheroprotective effects of anthocyanins in the study subjects. Four weeks of anthocyanin supplementation significantly decreased cardiometabolic risk factors including the average serum fasting blood glucose (FBG) (by 13.3%, P <.05) and lipid profiles by significant reduction in triglyceride (by 24.9%, P <.05) and LDL-C (by 33.1%, P <.05) in the MetS group. Anthocyanin supplementation also decreased high sensitivity C-reactive protein (hs-CRP) level (by 28%, P <.05) in females. However, no significant differences in serum UA (uric acid) and HDL-C were observed between anthocyanin pre- and post-treatment in both groups. Moreover, Anthocyanin supplements decreased ADP-induced platelet activation configuration expressed as P-selectin by 40% (P <.05). There was a positive correlation between decreased hs-CRP values and the levels of LDL-C and FBG in the MetS group (P <.05). These results support the hypothesis that anthocyanin supplementation exerts anti-atherogenicity effects by improving cardiometabolic risk factors and reducing thrombogenicity in the MetS population.
