Carotenoids

Carotenoids are yellow, orange and red plant pigments such as beta-carotene, lutein and lycopene. Some of them can be converted into vitamin A.

The complete formula matters

The AREDS2 formula contains lutein and zeaxanthin alongside vitamins C and E, zinc and copper. It replaces the beta-carotene in the older AREDS formula. A lutein-only product is therefore not the intervention represented by those results. 1
