lutein + zinc gluconate + vitamin A

This is a combination dietary supplement containing lutein, zinc gluconate, and vitamin A. Lutein is a carotenoid antioxidant that accumulates in the macula of the eye and helps filter harmful blue light, potentially reducing the risk of age-related macular degeneration (AMD) and cataracts. Zinc gluconate provides bioavailable zinc, an essential mineral for retinal health and function; it supports enzymes in the eye and plays a role in melanin production to protect against light damage. Vitamin A is crucial for vision as it forms part of rhodopsin, a protein that absorbs light in retinal receptors; deficiency can lead to night blindness or more severe ocular issues. This combination is commonly used as an eye health supplement to support visual acuity and reduce progression risk of AMD, often inspired by clinical studies such as AREDS2[3][8]. The formulation may be found under various multivitamin or "eye health" products but does not correspond to a single unique brand.
