What Is Zeaxanthin Powder?

Zeaxanthin powder is extracted from marigold. Zeaxanthin is one of the most common carotenoids in nature. It is an isomer of lutein. It gives many vegetables and other plants their distinctive yellow color, including peppers, corn, saffron, and goji berries. The human body cannot synthesize it, it must be obtained from the diet. Studies have shown that the retina contains two carotenoids, lutein and zeaxanthin. In the central macula, zeaxanthin is the predominant component, accounting for 75% of the total, while in the peripheral retina, lutein is the predominant component, usually 67% or more. Zeaxanthin is an excellent antioxidant.
