Could vitamin B3 save sight in rare genetic blindness?
NCT ID NCT07258667
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early study tests whether high-dose vitamin B3 (nicotinamide) can help preserve or improve vision in people with Leber's hereditary optic neuropathy (LHON), a rare genetic disease that causes sudden vision loss. Researchers will give 13 participants 2 grams of vitamin B3 daily for 12 months and track changes in eyesight. The goal is to see if this simple supplement can support eye cell health and slow vision decline.
