Glaucoma supplement trial halted early – no clear results
NCT ID NCT04784234
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a daily dietary supplement called GlaucoCetin could improve vision in people with open-angle glaucoma who already had some vision loss. Only 12 participants were enrolled before the trial was terminated early. The supplement contained a mix of ingredients thought to protect optic nerve cells, but because the study stopped, we don't have reliable data on whether it helped.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- GlaucoCetin (a dietary supplement containing curcumin, N-acetyl cysteine, ginkgo biloba, alpha-lipoic acid, citicoline, grape seed extract, green tea extract, coenzyme Q10, and other ingredients)
- What this could lead to
- If it had worked, GlaucoCetin might have pointed toward a way to slow vision loss in glaucoma by protecting optic nerve cells.
- What could go wrong
- The trial was terminated early with only 12 participants, so no reliable conclusions can be drawn. Dietary supplements often fail to show clear benefits in rigorous studies.
