First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tested a polyphenol-enriched supplement in 70 overweight or obese adults to see if it could improve body weight, fat mass, and metabolic health. Participants took either the active supplement or a placebo for a period, and researchers measured changes in weight, insulin sensitivity, and inflammation. The goal is to find a natural way to support weight management.
