Clinical Trial Summary

The purpose of the study is to evaluate the bioavailability of acetate, propionate and butyrate in healthy humans using a stable isotope technology.

In addition the level of acetate, propionate and butyrate production from inulin will be determined using the principle of isotope dilution.

Outcome

Type Measure Description Time frame Safety issue
Primary Concentrations of the short chain fatty acids (acetate, propionate and butyrate) in plasma and urine samples Participants performed each 4 test days and they were followed each test day for 12 hours, with sample collections at regular time points. Blood samples were collected every hour during the first 4 hours and afterwards every 20 minutes during 8 hours. Urine samples were collected during 24h in different fractions: 0-4h, 4-8h, 8-12h, 12-24h. 12 hours each test day and 4 test days/volunteer No
