01 Aug 2023 --- Daily kombucha consumption for four weeks demonstrated lower fasting blood glucose levels compared to the control group who drank a placebo beverage, making it a potential nutritional intervention for people with diabetes. “We were able to provide preliminary evidence that a common drink could have an effect on diabetes. We hope that a much larger trial, using the lessons we learned in this trial, could be undertaken to give a more definitive answer to the effectiveness of kombucha in reducing blood glucose levels and hence prevent or help treat Type 2 diabetes,” says Chagai Mendelson, lead author of the study.
