Carob extract supplement tested as potential prediabetes aid
NCT ID NCT07420998
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a liquid supplement made from carob extract can improve blood sugar control in people with prediabetes. Thirty adults with prediabetes will take either the carob supplement or a placebo before meals for a period of time. Researchers will measure changes in blood sugar and insulin levels to see if the supplement helps manage carbohydrate metabolism.
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 (NUTIFOOD)
- What this could lead to
- If it works, this could point toward a simple dietary supplement to help manage prediabetes and reduce the risk of developing type 2 diabetes.
- What could go wrong
- This is a very small, early-stage trial with only 30 people. The supplement may show no benefit over placebo, and results may not apply to everyone with prediabetes.
