NCT ID NCT07373795
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This small study tested whether gummy candies made with maqui berry could help overweight adults control their blood sugar after eating a carb-rich meal. Ten participants ate white bread alone, or with maqui berry gummies, and had their blood sugar and antioxidant levels measured over two hours. The goal was to see if the berry gummies could lower blood sugar spikes and raise antioxidant levels.
