Conclusions Resveratrol supplementation significantly increased FMD among patients with MetS and related disorders , but did not affect SBP and DBP .
Introduction There are current trials investigating the effect of resveratrol supplementation on endothelial function and blood pressures among patients with metabolic syndrome ( MetS ) ; however , the findings are controversial .
Aim This systematic review and meta- analysis of r and omized controlled trials ( RCTs ) were carried out to summarize the effects of resveratrol supplementation on endothelial activation and blood pressures among patients with MetS and related disorders .
Trans-Resveratrol Supplementation and Endothelial Function during the Fasting and Postprandial Phase: A Randomized Placebo-Controlled Trial in Overweight and Slightly Obese Participants
Studies on the effects of the long-term intake of trans-resveratrol on vascular function are conflicting . In addition , postpr and ial effects of long-term trans-resveratrol intake on endothelial function are not known . We therefore supplemented 45 overweight and slightly obese volunteers ( 25 men and 20 women ) with a mean ( ±SD ) age of 61 ± 7 years and body mass index of 28.3 ± 3.2 kg/m2 in r and om  order trans-resveratrol ( 2 × 75 mg/day ) or placebo capsules for 4 weeks , separated by a washout period of at least 4 weeks . At the end of each intervention period , brachial artery flow-mediated vasodilation ( FMD ) was measured before and after meal consumption . Plasma biomarkers for endothelial function , inflammation , and glucose and lipid metabolism were also determined . Compared with the placebo , trans-resveratrol did not affect fasting FMD ( 2.9 ± 1.4 % vs. 3.0 ± 1.9 % ; p = 0.69 ) . After the postpr and ial test , changes in FMD ( −0.7 ± 2.3 % vs. 0.2 ± 2.6 % ; p = 0.13 ) were also not significantly different . Postpr and ial changes in biomarkers were also comparable . In conclusion , for overweight and slightly obese volunteers , a daily intake of 150 mg of trans-resveratrol for 4 weeks does not change plasma biomarkers of endothelial function or inflammation in the fasting state or postpr and ial phase
