Melatonin may boost brain and blood sugar health in teens with diabetes
NCT ID NCT07592442
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether taking a melatonin supplement (3 mg each night for 6 months) could improve sleep, thinking skills, and blood sugar control in 70 adolescents with type 1 diabetes. Half received melatonin and half received a placebo. The researchers measured changes in blood sugar time-in-range, sleep quality, and executive function (like focus and planning). The goal was to see if this simple hormone supplement could help manage some common diabetes-related challenges.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- melatonin (3 mg tablet once daily)
- What this could lead to
- If it works, melatonin could become a simple, low-cost add-on to help teens with type 1 diabetes sleep better, think more clearly, and manage blood sugar more effectively.
- What could go wrong
- This is a small, completed trial with only 70 participants. Melatonin is not a diabetes treatment on its own, and any benefits may be modest or not apply to all teens. Long-term effects are unknown.
