Clinical Trial Summary

This study aims to study the digestibility of isolated duckweed protein. The digestibility of the isolated duckweed protein will be compared to an isolated benchmark protein whey.

Objective: The primary objective is to investigate the digestibility of isolated duckweed protein and the isolated benchmark protein whey.

Study design: The study is a cross-over, double blind, controlled trial in which study participants will visit the research facility on two occasions under fasting conditions. Subjects will receive two protein sources in randomized order with a washout period of one week. Blood will be collected via a catheter before and up-to 3 hours after protein consumption.

Study population: We aim to include 12 healthy volunteers aged 18-50 years. Intervention: Study participants will receive 20 grams of isolated duckweed protein and the isolated benchmark protein whey.

Main study parameters/endpoints: The main study parameter is blood amino acids measured before and after consumption of 20 g protein.

Outcome

Type Measure Description Time frame Safety issue
Other change in visual analogue scale (VAS) scores on intestinal complains On a scale ranging from worst-best outcome (higher scores are better) daily from day1 until day3 after the intervention
Primary Change in blood free amino acids (e.g. Degree of digestibility) postprandial test, determine free amino acids in blood samples collected before and after a postprandial challenge test 20 gram protein will be consumed and blood samples will be taken before and up to 3 hours after protein consumption
Secondary change in plasma insulin before and after a postprandial challenge test 20 gram protein will be consumed and blood samples will be taken before and up to 3 hours after protein consumption
Secondary change in plasma glucose before and after a postprandial challenge test 20 gram protein will be consumed and blood samples will be taken before and up to 3 hours after protein consumption
