The Claim

Oral supplementation with antioxidants (vitamin C, vitamin E, and β-carotene) reduces the rate of geographic atrophy progression toward the central macula by approximately 36% in individuals with non-central geographic atrophy due to age-related macular degeneration over a mean follow-up period of 3 years, as measured by annual fundus photography.

In plain English

Taking vitamin C, vitamin E, and β-carotene supplements daily slows the expansion of blind spots in the central vision by about 36% over three years in people with early-stage age-related macular degeneration.

See the scientific wording

Oral supplementation with antioxidants (vitamin C, vitamin E, and β-carotene) slows the rate of geographic atrophy progression toward the central macula by approximately 36% in individuals with non-central geographic atrophy due to age-related macular degeneration, as measured by annual fundus photography over a mean follow-up of 3 years, suggesting these nutrients may enhance natural foveal sparing mechanisms.

Why this might work

When people take antioxidant supplements, these nutrients travel through the blood and collect in the center of the retina, where they neutralize harmful molecules created by light exposure. This protection keeps the support cells in the retina alive and functioning, preventing them from dying off and stopping the blind spot from spreading toward the very center of vision.

  1. Study: Oral Antioxidant and Lutein/Zeaxanthin Supplements Slow Geographic Atrophy Progression to the Fovea in Age-Related Macular Degeneration

    Taking daily antioxidant pills with vitamin C, E, and beta-carotene helped slow the spread of blind spots in the retina toward the center of vision in people with a specific eye disease, based on a large, well-designed study. This means central vision may last longer.
