Resveratrol trial
Effects of Resveratrol on Diabetes Mellitus RV enhances the endothelial function, increases liver fatty acid oxidation, and decreases oxidative stress [ 49 ], leading to an improvement in insulin sensitivity [ 50 ].
Effect of Resveratrol on Cardiovascular Diseases Flow-mediated dilatation FMD of the brachial artery is a biomarker of endothelial function and cardiovascular health, with notable importance as an indicator of structural and functional endothelium changes [ 55 , 56 ]. Effect of Resveratrol on Obesity In a crossover study with 11 subjects, RV mimicked the effect of calorie restriction, reducing the metabolic rate, activating AMPK in muscle, and increasing the levels of SIRT1 and peroxisome proliferator-activated receptor gamma coactivator 1 alpha protein.
Figure 2. High-dose RV treatment showed a beneficial effect on both oxidative stress and some clinical outcome measures. RV plasma levels might be affected by metformin treatment; RV did not improve insulin sensitivity. Therefore, RV may help to decrease cardiovascular risk. Fasting glucose was unchanged, but postprandial glucose and three-hour glucose area under the curve decreased significantly. Insulin sensitivity using the Matsuda index improved.
Fasting lipid profile, CRP, and adiponectin were unchanged. Higher plasma RV concentration was associated with acute flow-mediated dilatation response. Lean and overweight, postmenopausal RV supplementation did not change plasma substrates and hormones glucose, plasma lipids, and insulin , adiponectin, leptin, CRP, and IL On three visits, the participants received two single-dose capsules. The capsules were combined to give the following treatments: 1 inert placebo, 2 mg t RV, and 3 mg t RV.
Healthy RV intake increased total-Hb and deoxy-Hb concentration, variables related to cerebral blood flow. High levels of sulfo- and glucuronide-conjugated RV compounds. Conclusions In this review, we have described the human clinical trials held in the last decade in which RV was determined in human plasma, urine, or feces.

Randomized, double-blind, placebo-controlled trial. Evaluate the metabolic effects in nonobese, postmenopausal women with normal glucose tolerance. No change in body composition, resting metabolic rate, plasma lipids, or inflammatory markers. No increase in liver, skeletal muscle, or adipose tissue insulin sensitivity. Randomized, placebo-controlled, double-blinded, and 2-arm parallel.
Follow up: either RES or placebo treatment for 4 weeks. Metabolic effects of high-dose RES in obese human subjects. Insulin sensitivity deteriorated insignificantly in both groups. No effect on blood pressure, resting energy expenditure, oxidation rates of lipid, ectopic or visceral fat content, or in inflammatory and metabolic biomarkers.
Randomized, double-blind, cross-over trial. Effects on markers of inflammation and oxidative stress in smokers. Uric acid, glucose, insulin, cholesterol, liver enzyme concentrations, and weight, waist circumference, and blood pressure values did not change significantly. Single-blind, vehicle-controlled, 1-arm trial. Therapeutic effects of RES on acneic skin. Global acne grading system GAGS score decreased by Histological analyses showed a decrease of No adverse effects were observed.
Topical application of 4 different moisturizing cream formulations on six sites on the non-exposed dorsal skin for 4 days. Histological analyses were blinded to the investigators. UV-induced erythema was mainly prevented by RTP and inhibited sunburn cell formation and melanin content. Randomized, unmasked, placebo-controlled trial. Follow up: 1 capsule of either placebo or a grape extract supplement mg containing 8 mg RES for 60 days.
Topical and systemic effects on age-related alterations to the skin, the skin antioxidant pool, and systemic oxidative stress levels. Systemic oxidative stress, plasmatic antioxidant capacity, and skin antioxidant power increased significantly. Skin moisturization and elasticity improved, while skin roughness and depth of wrinkles diminished.
