Summary

This study tested whether adding a mangosteen supplement to standard diabetes drugs (sitagliptin/metformin) improves blood sugar control in 47 adults with type 2 diabetes. Participants took either the standard drugs alone or with mangosteen for 12 weeks. Researchers measured changes in HbA1c, insulin resistance, and inflammation.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
mangosteen supplement (Garcinia mangostana extract)
What this could lead to
If it works, this could point toward a natural supplement to help manage blood sugar and reduce inflammation in type 2 diabetes.
What could go wrong
This is a small, early-stage trial with only 47 patients. Results may not apply to everyone, and supplements are not a replacement for standard care.
