Effect of Resveratrol & Vitamin C on Insulin Resistance Among

Status Active, not recruiting

Clinical Trial Summary

Hormonal and metabolic changes because of postmenopause increase body weight, central abdominal fat, alter lipid profile and insulin resistance, those factors increase the risk up to 60% to develop metabolic syndrome, diabetes and cardiovascular diseases. Because there is no efficient antioxidant therapy in postmenopausal women, this study proposes a therapy with resveratrol and vitamin C to increase the total antioxidant capacity; as well as to decrease insulin resistance and in consequence decreased the risk of diabetes, metabolic syndrome and cardiovascular disease

Clinical Trial Description

Currently, there are not studies that demonstrate an efficient antioxidant therapy in postmenopausal women, to increase the total antioxidant capacity and to decrease insulin resistance and biochemical parameters of cardio-metabolic risk. Therefore, the aim of this study is to evaluate the effect of the co-administration of resveratrol and vitamin C on insulin resistance and antioxidant capacity by a double-blind randomized clinical trial. A population of 270 postmenopausal women will be studied, stratified into 3 groups: Group 1: Three-month administration of vitamin C 500 mg daily + placebo Group 2: Three-month administration of resveratrol 500 mg daily + placebo Group 3: Three months administration of vitamin C 500 mg daily and resveratrol 500 mg daily as antioxidant therapy. All participants will be monitored monthly for a period of 3 months: glucose, insulin, uric acid, Homeostatic Model Assessment (HOMA), total cholesterol (TC), triglycerides (TGC), High density lipoproteins-cholesterol (HDL- C), low density lipoproteins-cholesterol (LDL), blood pressure, body mass index (BMI). The antioxidant efficiency in erythrocytes by the quantification of antioxidant enzymes (superoxide dismutase, catalase, glutathione reductase and glutathione peroxidase), as well as total antioxidant capacity in plasma. In order to corroborate the oxidative damage, the product of the lipoperoxidation malondialdehyde and the carbonylation of proteins will be evaluated by spectrophotometric techniques before and three months after the intervention. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
