However, Thazhath et al. studied two incretin hormones that affect postprandial hyperglycemia: glucose-dependent insulinotropic polypeptide GIP and glucagon-like peptide 1 GLP-1 from the intestine.
In healthy people, both hormones stimulate insulin, but in type 2 patients, only GLP-1 can act to stimulate insulin. GLP-1 can also suppress glucagon secretion and energy intake and slow gastric emptying, thereby targeting postprandial hyperglycemia.
In rodent models, resveratrol has been shown to upregulate GLP-1 and lower glycemia, but Thazhath et al. found that in human patients, resveratrol had no effect on GLP-1 secretion, glycemic control, gastric emptying, body weight, or energy intake.
Brasnyo et al. also found that resveratrol did not cause any changes in GLP-1 or GIP levels in diabetes patients. However, they did show that resveratrol significantly decreased insulin resistance and blood glucose and delayed glucose peaks after meals. Oxidative status is a promising area of diabetes research because oxygen free radicals are involved in the insulin resistance characteristic of type 2 diabetes.
In addition, Brasnyo et al. found that resveratrol activated the Akt insulin signaling pathway by increasing the phosphoAkt:Akt ratio in platelets.
Crandall et al. studied older adults with impaired glucose tolerance IGT , a major risk factor for diabetes as well as cardiovascular disease. They found that although fasting plasma glucose was unchanged with resveratrol treatment, peak postmeal glucose and 3-h glucose declined.
Postmeal insulin fell as well, and insulin sensitivity improved. NAFLD is the most common chronic liver disease world-wide, and is an obesity-related disease. As implied by its name, patients with NAFLD consume little to no alcohol, yet their livers pathologically resemble those with alcohol-induced liver damage.
As resveratrol has only been tested in a small number of clinical trials, there can be no definitive conclusions regarding its effectiveness as a treatment for NAFLD, although certain trends can be observed. A meta-analysis of placebo-controlled clinical trials indicated that resveratrol treatment has negligible effects on attenuating NAFLD, given the small improvement in NAFLD features.
In one study by Chachay et al. In both studies, there was no difference in the levels of ALT and AST, the lipid profiles, or expression of genes related to NAFLD between the resveratrol and the placebo groups. In addition, one study shows that resveratrol may be a beneficial treatment for NAFLD when used as a supplement to lifestyle modifications, including exercise and diet.
The patients in this study showed reduced levels of ALT, inflammatory factors such as IL-6 and NF-κB, as well as improved lipid profiles.
As mentioned above, definitive conclusions cannot be drawn until more clinical trials testing various dosages, durations of treatment, and contexts of treatment have been conducted. Clinical trials of resveratrol as an inducer of calorie restriction-like effects as a treatment of obesity have produced mixed results.
Timmers et al. Resveratrol was more effective in certain types of cancer than in others. For example, it seems to epigenetically reduce the expression of certain breast cancer-related genes, but caused severe adverse events specifically in multiple myeloma patients.
Treatment of patients with AD and stroke was beneficial in all three clinical trials presented, suggesting that resveratrol would be an effective treatment for neurological disorders. However, more clinical trials in this area must be conducted in order to validate this trend.
Resveratrol was found to be beneficial for patients with cardiovascular disorders, but perhaps more so in certain demographics than in others, as it was not found to be effective in extremely overweight individuals, and detrimental in schizophrenic patients.
In diabetic patients, resveratrol was able to increase insulin sensitivity, decrease blood glucose levels, and positively regulate several other biomarkers associated with diabetes.
The effects of resveratrol on NAFLD remain inconclusive, as half of the clinical trials found that resveratrol positively affected NAFLD biomarkers, while the other half observed no changes in those same biomarkers.
Similarly, clinical trials of resveratrol in obesity provided conflicting results. In addition, future clinical trials should study whether resveratrol is more efficacious in certain patient types. Pharmaceutical efforts should focus on developing a resveratrol derivative with better bioavailability.

In addition, resveratrol may serve as a therapeutic agent for rheumatoid arthritis , as well as for male infertility and testicular malfunction. More research is needed, as most of the above studies are animal studies. People use resveratrol for a number of other ailments, including stomachaches, hepatitis, urinary tract infections, and fungal diseases.
While resveratrol has fewer potential side effects than potential benefits, some studies show that it may behave as a pro-oxidizing agent in the body. This means that, rather than consistently work to slow or prevent cell damage that free radicals cause, resveratrol may exhibit pro-oxidant properties, leading to cellular DNA damage and oxidative stress.
Generally, if a person takes resveratrol in small amounts for a short time, they will not experience side effects. However, at doses of 2. In a small study from , one participant developed fever and bicytopenia reduced blood cells while receiving 1.
High doses of resveratrol can inhibit enzyme activity that could increase the bioavailability and toxicity of certain drugs. There is also a relationship between resveratrol and transporter drugs, though scientists do not yet fully understand it.
Finally, research suggests that resveratrol may hinder human platelet aggregation. As a result, there is an increased risk of bleeding when people take resveratrol with anticoagulant drugs, antiplatelet drugs, or nonsteroidal anti-inflammatory drugs. The easiest way to consume resveratrol in safe amounts is via grapes, wine, blueberries, cranberries , pomegranates, and juices that contain these fruits.
Some people also take resveratrol supplements, especially for lowering blood pressure. Many of these supplements contain much higher doses of resveratrol than a person would naturally consume from food sources. Clinical trials show that it is technically safe to take resveratrol in doses of up to 5 g per day , though taking more than 2.
A review found that milligrams or more of resveratrol effectively lowered systolic blood pressure but had no significant effects on diastolic blood pressure. More studies are necessary to determine a safe, effective dose for humans, as human trials have found many conflicting results.
Overall, people have different tolerance levels for resveratrol, and there is no universally recommended dose. A person should talk with a healthcare professional about the dose that might be safest and most beneficial for their body.
Resveratrol is a naturally occurring compound present in grapes, some berries, and other fruits and nuts. It often mimics antioxidant activity in the body and may provide many health benefits. Research most supports its use for cardiovascular protection and blood pressure regulation.
People may consume resveratrol through foods or supplements. There is no conclusive recommended dosage for resveratrol, but consuming large amounts may lead to gastrointestinal upset. A doctor, dietitian, or other qualified health professional may be helpful in determining the appropriate amount of resveratrol for an individual.
People have cultivated grapes for 8, years.
