Glutamine Protects Eye Health and Helps Prevent Vision Loss

7 minutes

Glutamine is the most abundant amino acid in your body, supporting tissue repair, immune function, and energy production, while also helping protect your eyes from vision loss
Research shows your eyes rely on glutamine to fuel photoreceptors, the light-sensing cells in the retina, making it a key nutrient for long-term visual health
When glutamine metabolism is disrupted, photoreceptors degenerate rapidly, triggering harmful stress pathways that accelerate retinal thinning and increase the risk of blindness
Studies demonstrate that restoring glutamine balance calms cellular stress, preserves retinal thickness, and keeps eye cells alive, offering new strategies for preventing eye disease
You can support natural glutamine levels through diet by eating foods such as grass fed beef, wild-caught Alaskan salmon, pastured eggs, raw dairy, spinach, cabbage, beans, and even white rice
