Summary of key points from the research "Effects of resveratrol supplementation on multiple health outcomes: an umbrella review of systematic reviews and meta-analyses of randomized controlled trials" published in the Nutrition Journal (2026).

This Umbrella Review collated and analyzed data from 45 systematic reviews covering 129 health associations and 68 clinical outcomes from randomized controlled trials (RCTs) to draw definitive conclusions about the efficacy of resveratrol supplementation in humans.

The results provide evidence of a high level of reliability. (High-Certainty Evidence)

According to the GRADE system, there are 4 health outcomes that clearly demonstrate the benefits of taking resveratrol:

1. Reduce waist circumference (Waist Circumference): Helps significantly reduce the size of the waist circumference. (Average decrease -0.80 cm.)

2. Reduce blood pressure in patients with type 2 diabetes: Helps control and reduce blood pressure levels for the better in people with diabetes.

3. Reduce total cholesterol in overweight adults (Total Cholesterol): significantly reduces total cholesterol levels in overweight adults. (average decreased -0.19 mmol/L)

● Results with moderate evidence of reliability. (Moderate-Certainty Evidence)

Research has found evidence that resveratrol It may be useful in the following areas:

* Metabolic system and liver: Helps promote the functioning of the glucose metabolism system and helps improve fatty liver disease (Hepatic Steatosis).

* Reducing inflammation: has the effect of reducing inflammatory indicators in the body. (Inflammation)

* Brain and nervous system: Helps promote the performance of working memory (Working Memory).

* Blood Vessels and Kidneys: Helps protect endothelial health and improves kidney function.

* Hormone system: Helps reduce the level of certain hormones that are too high.

Summary for use

The quality of most of the research analyzed was rated as medium to high level (Moderate-to-High Quality) according to AMSTAR standards

> Bottom line: Resveratrol supplementation has the most pronounced benefit in people at metabolic risk, such as those who are overweight. Diabetic patients or those who have problems with waist circumference and blood fat
