Zeaxanthin is a carotenoid pigment primarily known for its role in eye health, but it also serves as a powerful antioxidant. In the context of physical performance and supplementation, antioxidants like zeaxanthin are valued for protecting cells from oxidative stress caused by intense physical activity.
This compound is particularly concentrated in the retina, where it protects against light-induced oxidative damage. However, its systemic antioxidant properties can benefit athletes by reducing muscle fatigue, supporting recovery, and enhancing overall cellular protection.
Zeaxanthin works synergistically with other carotenoids, such as lutein, contributing to overall antioxidant defense, which is crucial for maintaining performance, recovery, and long-term health.
Synonyms:
(None widely used beyond “Zeaxanthin”)
Benefits:
- Powerful antioxidant activity
- Supports cellular protection against oxidative stress
- Contributes to reduced muscle fatigue
- Supports eye health and visual performance (beneficial for outdoor athletes)
Sources:
- Found naturally in leafy green vegetables (spinach, kale), corn, orange peppers, egg yolks, and goji berries
- Extracted from marigold flowers for use in supplements
Observations:
Often combined with lutein in antioxidant formulas. Generally considered safe, with typical supplemental doses ranging from 2 to 10 mg per day.
No major interactions are commonly reported, but excessive intake offers no additional benefit beyond saturation levels in tissues.
