Jarrow Formulas Lutein is a blend of lutein and zeaxanthin extracted from marigold petals and then purified into crystalline form. These carotenoids (a family of brightly colored pigments in plant foods) are less common than their better-known relative, beta-carotene, but they appear to offer more and greater benefits to the body. In particular, lutein and zeaxanthin have been shown clinically to support visual function and to protect the health of eye tissues as we age.
