Delphinidin-Rich Maqui Berry Extract (Delphinol®) Lowers Fasting and Postprandial Glycemia and Insulinemia in Prediabetic Individuals during Oral Glucose Tolerance Tests

Table 1

Statistical evaluation of acute dose effects related to Delphinol intake on fasting glucose and insulin in 36 subjects, prior to OGTT. Each basal value was obtained at different days in the morning, with subjects fasting overnight and in the morning, 60 min after intake of respective single Delphinol doses. Dose zero was the diagnostic test in which no Delphinol was administered (baseline).
