Lutein and zeaxanthin are carotenoids generally known for their use in eye support by reducing oxidative stress. Additionally, lutein and zeaxanthin have recently been studied and shown to support cognitive function in older adults.
Most research show health benefits in taking 10 mg/day of a lutein supplement and 2 mg/day of a zeaxanthin daily.
Mode of Action
Lutein and zeaxanthin have antioxidant abilities which protect from harmful damage from free radicals and other factors such as poor diet that increase the risk of developing age-related eye problems. In the process, antioxidants like lutein and zeaxanthin protect healthy cells and halt malignant cells.
Research suggests that LD50 of both zeaxanthin and lutein is greater than 2 grams/kg of body weight. Please note, this product should be avoided if you are allergic to daisy-like flowers.
