Delphinol®, delphinidin-rich maqui berry standardized extract positively influences levels of fasting and postprandial blood glucose, as well as insulin levels in pre-diabetic subjects.

In the current study, pure glucose absorption was explored in an open trial. The results show postprandial blood glucose levels were lowered with all tested doses of 60, 120 and 180 mg Delphinol® in a dose-dependent manner, due to a drop in fasting glucose levels. The blood glucose peaks shifted from 30 minutes under placebo to 60 minutes after pure glucose intake with Delphinol®.

Insulin levels were also lowered in a direct way, the underlying mechanism of action could be hypothesized.  

Further studies to explore the mechanism of action are underway.
