25gr. Glucomedics vs 25gr. Zusto

This is an experimental study enrolling 10 healthy female subjects. The study compares the blood glucose and insulin responses after consumption of 100ml water, sweetened with 25gr Zusto® and 100ml water sweetened with 25gr Glucomedics® (standard drink). Subjects need to be fasted for at least 8 hours before all visits. At visit 1, five women will consume the solution with 25gr Zusto®, the other five will have the solution with 25gr Glucomedics®. On visit 2, groups will be switched. Visit 1 and 2 will be performed within approximately one week interval.

Both drinks will be identical in amount of water and only be different by the use of 25gr Glucomedics® and 25gr Zusto®.

Before intake of the drink, vital signs, weight and bedside blood glucose and baseline blood samples - 15' and 0' for glucose, insulin and C-peptide will be taken at visit 1 and 2. Both drinks will be consumed within 5 minutes and time of start and end of intake of Zusto® / Glucomedics® will be documented.

Blood samples for glucose, insulin and C-peptide will be taken at 15', 30', 60', 90', 120' and 180' after start of intake 25gr Zusto® and 25gr Glucomedics®.
