Berry and green tea extracts tested for weight loss in new study
NCT ID NCT06911346
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether eating more plant-based foods or taking polyphenol supplements (like green tea and berry extracts) can help overweight adults lose weight and improve heart health. 99 participants will follow a calorie-restricted diet for 12 weeks, with one group eating extra fruits and nuts, another taking polyphenol supplements, and a control group getting a placebo. Researchers will measure weight, blood pressure, and blood markers to see if these approaches work.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Polyphenol-rich foods and supplements (plant extracts from maqui, green tea, olive leaf, cranberry, grape, plus apple, blueberries, hazelnuts, olive oil, coffee)
What this could lead to
If it works, this could point toward a simple dietary strategy to help manage weight and lower heart disease risk.
What could go wrong
This is a small, early-stage trial with only 99 participants over 12 weeks. Results may not apply to everyone, and the supplements may not work better than a healthy diet alone.
