Worth it?
4/10. Zeaxanthin is a carotenoid antioxidant found in the macula of the eye. Supplementation *may* offer some protective benefits against age-related macular degeneration (AMD), but the effects are subtle and primarily preventative. Evidence at realistic supplement doses is limited. Overhyped as a vision enhancer for healthy people.

"There is a good consensus that zeaxanthin is important for eye health and acts as an antioxidant. However, the degree to which supplementation provides significant benefits in the absence of a deficiency or pre-existing condition is debated. Clinical research uses much higher doses than typical supplements."
Zeaxanthin is a carotenoid that concentrates in the macula of the eye. It acts as an antioxidant and may help protect against damage from blue light and oxidative stress, potentially reducing the risk of AMD. Supplementation is most beneficial for those with low dietary intake or at risk of AMD.
