Summary

This study tests whether taking a prebiotic fibre supplement for 6 months can help people with type 1 diabetes have fewer dangerous low blood sugar episodes. Researchers will also see if it improves overall blood sugar control and gut health. The study involves 144 people aged 7 and older who were diagnosed with type 1 diabetes in the past year.
