Impact of Food Intake on Berberine Kinetics

A single dose of 1000 mg berberine in two capsules will be administered with 250 ml of still water in the overnight fasting condition as the control condition. The two intervention arms will test the effect of different meals on berberine kinetics. A total amount of 12 blood samples at defined time points (baseline; 1; 2; 3; 4; 5; 6; 7; 8; 24 h) will be taken. For glucose and insulin measurements, blood samples will be obtained at 4 h, 5 h and 6 h .
