A recent human clinical trial showed that Prolibra weight management solution from Glanbia Nutritionals considerably reduced postprandial glycemia in a dose dependant manner and resulted in a lower glycemic index (GI).

Participants experienced a statistically significant reduction of up to 37.8 Glycemic Index units when Prolibra was added to a liquid meal consisting of 50 grams of glucose. Glycemic Index Laboratories conducted the research for Glanbia Nutritionals.

Ten healthy men and women (Average BMI 33 kg/m2) completed the multi-day glucose measurement study with Prolibra. Subjects fasted 10-14 hours, were weighed, took a fasting blood sample, consumed a test meal, and took blood samples at 15, 30, 45, 60, 90 and 120 minutes thereafter. Three Prolibra dose levels were used to determine the glycemic-index-lowering potential of the ingredient within a liquid meal: 6.1 grams, 12.2 grams and 24.4 grams.

The study found that the addition of Prolibra significantly reduced postprandial glycemia to all test meals, with a reduction of up to 37.8 GI units. Increasing the dose of Prolibra caused a greater decrease in GI values in an essentially linear relationship.

According to the study, “the addition of Prolibra to a liquid meal in the dose range of 6.1-24.4 grams will result in a reduction of GI value of the product by approximately 7.6-37.8 GI units, respectively.”
