Lutein and zeaxanthin are found in high levels in foods such as green vegetables, egg yolk, kiwi fruit, grapes, orange juice, zucchini, squash, and corn. For some commercially available supplements, lutein is extracted from marigold petals. Lutein and zeaxanthin are carotenoids in the macular region of the retina of the eye (macular pigment), and thus lutein has been studied for its use in treating cataracts, preventing macular degeneration and retinal degeneration. Lutein and zeaxanthin also have antioxidant capabilities as well as the ability to trap short-wavelength light. The potential for carotenoids, including lutein, to play a preventing role in cardiovascular disease and cancer was recognized in the 1990s. Most of the information surrounding lutein is based on blood and/or dietary intakes of lutein compared with disease states (e.g. cancer, eye disorders, lung function, muscle soreness, obesity, and pre-eclampsia). More evidence is needed before recommendations can be made in these fields.

Bilberry, a close relative of blueberry, has a long history of medicinal use. The dried fruit has been popular for the symptomatic treatment of diarrhea, for topical relief of minor mucus membrane inflammation, and for a variety of eye disorders, including poor night vision, eyestrain, and myopia. Bilberry fruit and its extracts contain a number of biologically active components, including a class of compounds called anthocyanosides. These have been the focus of recent research in Europe. Bilberry extract has been evaluated for efficacy as an antioxidant, mucostimulant, hypoglycemic, anti-inflammatory, "vasoprotectant," and lipid-lowering agent. Although pre-clinical studies have been promising, human data are limited and largely of poor quality. At this time, there is not sufficient evidence in support of (or against) the use of bilberry for most indications. Notably, the evidence suggests a lack of benefit of bilberry for the improvement of night vision. Bilberry is commonly used to make jams, pies, cobblers, syrups, and alcoholic/non-alcoholic beverages. Fruit extracts are used as a coloring agent in wines.
