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. Read more about this study

About this study

Official title: Evaluation of the Bioavailability and Production of Short Chain Fatty Acids in the Colon. A Stable Isotope Study in Healthy Humans.

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.

Being tested
13C-labeled Acetate, 13C-labeled propionate, 13C-labeled butyrate, Inulin
Keywords

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: 12 hours each test day and 4 test days/volunteer
