NCT ID NCT07255326

First seen Jun 24, 2026 · Last updated Jul 01, 2026 · Updated 3 times

Summary

This completed trial tested whether daily omega-3 fish oil supplements can help maintain healthy blood vessels in the eyes of adults with type 1 diabetes. 82 participants took either a 1000 mg omega-3 capsule or a placebo for the study, with regular eye exams to monitor retinal changes. The goal was to see if the supplements could slow early signs of diabetic retinopathy.

What this could mean

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

Active substance

Omega-3 fatty acid supplements (fish oil)

What this could lead to

If omega-3 supplements are shown to support retinal blood vessel health, this could point toward a simple dietary approach to help manage eye complications in type 1 diabetes.

What could go wrong

This is a small, completed trial with 82 participants, so results may not apply to everyone. Omega-3 supplements are generally safe but may cause mild stomach upset, and the effect on preventing vision loss is not yet proven.
