Carotenoids are a class of phytochemicals that give plants, vegetables and fruits their rich, eye-pleasing color. There are more than 600 known carotenoids, including the ones most commonly found in our diet - beta carotene, cryptoxanthin, lutein, lycopene, zeaxanthin, and astaxanthin.
Almost all carotenoids are free radical scavengers, helping to protect tissues from the damaging effects of oxidation.* In addition, the molecular structure of a carotenoid helps it to absorb light, especially blue light, which can be harmful to sensitive ocular structures.*
