First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study will test whether supplements made from bilberries and olives can reduce inflammation and oxidative stress in people with prediabetes who are overweight. Researchers will collect blood, urine, and stool samples from 60 participants to measure changes in key health markers. The goal is to see if these natural food compounds could help manage early metabolic problems.
