What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
traditional kefir (fermented milk drink)
What this could lead to
If it works, this could point toward a simple dietary supplement to help manage blood sugar and reduce heart disease risk in people with or at risk for type 2 diabetes.
What could go wrong
This is a small, early-stage study (156 people) testing a dietary supplement, not a drug. Results may not be dramatic or apply to everyone, and kefir may cause digestive discomfort in some people.
