The drug also reduced homeostasis model assessment of insulin resistance ( HOMA-IR ) index , systolic blood pressure , and diastolic blood pressure among participants with T2DM .
The changes in hemoglobin A1c ( HbA1c ) , low-density lipoprotein cholesterol , and high-density lipoprotein cholesterol were negligible .
Subgroup analysis comparing the resveratrol supplementation doses of < 100 mg/d versus ≥ 100 mg/d revealed a significant difference in fasting plasma glucose .
In particular , the latter dose presented more favorable results .
This meta- analysis provides evidence that supplementation of resveratrol may benefit management of T2DM
Although the regular consumption of resveratrol has been known to improve glucose homeostasis and reverse insulin resistance in type 2 diabetes mellitus ( T2DM ) , the reported results are inconsistent .
Thus , we aim ed to assess the effects of resveratrol on glycemic control and insulin sensitivity among patients with T2DM .
Resveratrol improves insulin sensitivity, reduces oxidative stress and activates the Akt pathway in type 2 diabetic patients.
Although resveratrol has widely been studied for its potential health benefits , little is known about its metabolic effects in humans . Our aims were to determine whether the polyphenol resveratrol improves insulin sensitivity in type 2 diabetic patients and to gain some insight into the mechanism of its action . After an initial general examination ( including blood chemistry ) , nineteen patients enrolled in the 4-week-long double-blind study were r and omly assigned into two groups : a resveratrol group receiving oral 2 × 5 mg resveratrol and a control group receiving placebo . Before and after the second and fourth weeks of the trial , insulin resistance/sensitivity , creatinine-normalised ortho-tyrosine level in urine sample s ( as a measure of oxidative stress ) , incretin levels and phosphorylated protein kinase B (pAkt):protein kinase B ( Akt ) ratio in platelets were assessed and statistically analysed . After the fourth week , resveratrol  significantly decreased insulin resistance ( homeostasis model of assessment for insulin resistance ) and urinary ortho-tyrosine excretion , while it increased the pAkt : Akt ratio in platelets . On the other h and , it had no effect on parameters that relate to β-cell function ( i.e. homeostasis model of assessment of β-cell function ) . The present study shows for the first time that resveratrol  improves insulin sensitivity in humans , which might be due to a resveratrol-induced  decrease in oxidative stress that leads to a more efficient insulin signalling via the Akt pathway
