First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a daily prebiotic supplement (Molkosan®) could improve blood sugar and other health markers in people with type 2 diabetes. Twelve adults took a low dose (20 ml per day) for 12 weeks. Researchers measured changes in glucose tolerance, insulin levels, and HbA1c to see if the supplement might help manage the condition.
