ClinConnect Summary

This clinical trial is looking at how well short-chain fatty acids (SCFAs) are absorbed into the bloodstream when they are given in two different parts of the intestines: the small intestine and the colon. Short-chain fatty acids are important nutrients that can affect our health, and the researchers want to find out if the location where these acids are administered makes a difference in how much gets into the blood. Healthy volunteers aged 18 to 50 who meet certain health criteria will participate in this study by taking capsules containing SCFAs on two different days, with blood samples taken afterward to see how much of the SCFAs are absorbed.

To be eligible, participants must be healthy adults with a normal weight, meaning their body mass index (BMI) falls between 18.5 and 25. People with certain gastrointestinal issues, those who have had major abdominal surgeries, or those on specific diets like vegan or gluten-free will not be able to participate. During the study, participants will take the capsules on two separate days, and they'll need to avoid certain medications or supplements before and during the trial. Overall, this study aims to improve our understanding of how our bodies process important nutrients like SCFAs, which could have implications for digestive health.
