Polyphenol from grape skins and Japanese knotweed, famous for extending lifespan in yeast and mice. It has been tested in many human trials without convincing clinical benefit. Umbrella reviews rate its effects on blood sugar, cholesterol and blood pressure as trivial or very low certainty, and a meta-analysis of human brain and mood trials found the animal results are not replicated in people.
8 of 15 results reported a benefit, from 4 published studies.
4 studies, including a review of trials
These are the figures the studies reported, not a prediction for any one person. Where several studies measured the same thing in the same unit, we show a simple average and say so. Every individual result is listed below.

Every published result for this pair, extracted and audited.
These charts group published studies by what they reported and how they were run — green marks studies that reported a benefit for this pairing. Tiers run from pooled analyses of many trials (strongest) to one-off observational reports.
