NMN Calmed Eye Inflammation and Slowed Blood Vessel Damage in Mice

Key Insight

This early animal study suggests NMN may deserve testing for age-related eye disease.


Wet macular degeneration happens when abnormal blood vessels grow under the retina and scar tissue forms. In mice with laser-induced damage mimicking this, NMN shrank the abnormal vessel growth and cut inflammation. It also reduced the scarring that drives late-stage vision loss. This is early animal work, so it says nothing yet about NMN supplements and human eyesight.
