Lutein and zeaxanthin are xanthophyll carotenoids that humans obtain only from diet or supplements and that concentrate in the macula, where they filter blue light and scavenge reactive oxygen species^{7, 8}. Supplementation is used to raise macular pigment, in age-related macular degeneration (AMD), and for eye strain and visual performance in heavy screen users. Typical patients are older adults with intermediate AMD and people who eat few leafy greens or egg yolks⁸.

Macular pigment rises more with higher intakes than with diet alone, though older reviews found insufficient evidence⁸. In preterm infants, a 2025 Cochrane review found supplementation probably reduced severe retinopathy of prematurity but had little or no effect on retinopathy of any stage⁹. Products listing lutein and zeaxanthin are mostly softgels and capsules, with some gummies; see Form comparison.

Some product labels declare soy as an allergen⁶, and two ask users to discontinue use before surgery⁶. Most labels route medication and pregnancy questions to a healthcare professional⁶.
