NCT ID NCT03717311
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This pilot study gave 6 healthy women a breakfast containing wheat bran with a special carbon label (13C) to track how it is fermented in the gut. Over 24 hours, researchers collected breath, urine, blood, and stool samples to measure breakdown products. The goal is to identify new biomarkers that reflect fiber digestion, which could lead to better dietary advice in the future.

Active substance
13C-enriched wheat bran
What this could lead to
If successful, this could help develop simple tests to measure how well people digest fiber, improving dietary recommendations.
What could go wrong
This is a very small pilot study with only 6 participants, so results may not apply to everyone. It is designed to find markers, not to test a treatment.
