Main inclusion criteria:
- Male and female subjects with prediabetic HbA1c values between 5.7% – 6.4% and/or fasting glucose = 5.6 mmol/L (= 100 mg/dL) and = 6.9 mmol/L (= 125 mg/dL) (in venous plasma) (twice confirmed at two independent days if HbA1c is < 5.7%)
- Body mass index 19-35 kg/m2
- Current Non-smoker
- Signed informed consent form
- No changes in food habits or physical activity 3 months prior to screening and during the study
- If applicable, stable intake of chronic medication of at least 4 weeks
Main Exlusion criteria:
- Diagnosed type 2 diabetes mellitus with medical treatment
- Presence of disease or drug(s) influencing digestion and absorption of nutrients
- Intake of medications known to affect glucose tolerance, e.g. diabetic medication, SGLT-2 inhibitors, GLP-1 receptor agonists, steroids, protease inhibitors or antipsychotics
- Known inflammatory and malignant gastrointestinal diseases (i.e. colitis ulcerosa, Morbus Crohn, celiac disease, malignant diseases e.g. colon-cancer, rectum cancer, pancreatitis)
- Chronic intake of substances affecting blood coagulation (e.g. acetylic acid (100 mg as standard prophylactic treatment allowed when dose is stable 1 month prior to screening), anticoagulants, diuretics, thiazides (diuretics and thiazides allowed e.g. for hypertension treatment when dose is stable 1 month prior to screening)), which in the Investigator’s opinion would impact patient safety
- Severe liver or renal disease or laboratory evidence of hepatic dysfunction (i.e. alkaline phosphatase, ALT, AST >3 x ULN)
- Acute gastrointestinal diseases including diarrhea and/or vomiting within the last 2 weeks
- Clinically relevant findings as established by medical history, physical examination, clinical laboratory and/or vital signs
- Intake of food supplements known to affect glucose tolerance, e.g. cinnamon capsules, conjugated linoleic acids within 4 weeks prior to Visit 1 or during the study
