Benefits
Eye and macular health
Lutein and zeaxanthin concentrate in the macula of the eye, where they support macular pigment density and protect against blue-light and oxidative stress.
Visual performance
In randomized research, lutein and zeaxanthin improved measures of visual performance such as glare tolerance and contrast.
Antioxidant protection
As carotenoid antioxidants, they help protect the eye and skin from oxidative and light-induced stress.
Mechanism of action
Macular pigment
Lutein and zeaxanthin build up in the macula, filtering harmful blue light and quenching free radicals to protect the retina.
Antioxidant action
The carotenoids scavenge free radicals generated by light exposure, supporting long-term eye health.
Clinical trials
Randomized, double-blind, placebo-controlled study of lutein and zeaxanthin on visual and cognitive performance. (Parekh et al. 2024, Advances in Therapy)
Healthy participants.
Lutein and zeaxanthin supplementation improved measures of dynamic visual and cognitive performance versus placebo.
