Summary

This study is testing whether a high-fiber supplement called Trimtab can help preserve beta-cell function in children aged 6 to 12 who were recently diagnosed with type 1 diabetes. For 12 weeks, participants will take the supplement daily, and researchers will measure C-peptide levels (a marker of insulin production) and gut bacteria changes. The goal is to see if a simple dietary change can slow the loss of insulin-making cells.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Trimtab (a high-fiber grain powder)
What this could lead to: If it works, this could point toward a dietary approach to help preserve insulin production in children with new-onset type 1 diabetes.
What could go wrong: This is an early-stage study with only 110 participants, and the intervention is a dietary supplement, not a drug. It may not show a clear benefit, and results may not apply to all children with type 1 diabetes.
