Effect of a Plant-based Hydrolysates Daily Consumption on the HbA1c of Pre-diabetic Subjects

Pre-clinical data on human skeletal muscle cells and mouse Type 2 diabetes model have shown a blood glucose lowering effect of the plant-based hydrolysates.

The first objective of the study is to evaluate the effect of a once daily administration of 2 different cereal protein hydrolysates versus placebo, when consumed over a 12-week period, at reducing the preferred outcome measure identified by the European Food Safety Authority i.e. glycated haemoglobin (HbA1c) levels in pre-diabetic volunteers who are otherwise healthy subjects.

The second objective of the study is to evaluate the effect of a fixed daily administration of 2 different cereal protein hydrolysates versus placebo, when consumed over a 12-week period on further supportive measures like Post-prandial glucose/insulin levels, fructosamine level, fasting plasma glucose level, vital signs and blood pressure, weight and BMI.

Inclusion criteria

Exclusion criteria

The Principal Investigator will discuss any uncertain cases directly with the study sponsor prior to inclusion of any such subjects)
• Low hemoglobin or hematocrit (i.e., lower than normal ranges specified and in-use at the local laboratory designated for this study),
