Summary

This study tests whether a liquid carob extract can improve blood sugar levels in 70 adults with prediabetes. Participants take the extract or a placebo twice daily for 90 days. Researchers will measure blood glucose and insulin responses to see if the extract helps control blood sugar and may prevent progression to type 2 diabetes.

What this could mean

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

Active substance
carob extract (dietary supplement)
What this could lead to
If it works, this could offer a natural supplement to help manage blood sugar and reduce the risk of developing type 2 diabetes.
What could go wrong
This is a small, early-stage trial with only 70 participants. The supplement may not significantly improve glucose control, and results may not apply to everyone with prediabetes.
