The Claim
Supplementing with lutein and zeaxanthin (10 mg and 2 mg daily) does not significantly reduce the risk of progression to advanced age-related macular degeneration in adults aged 50–85 with high-risk drusen.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking 10 mg of lutein and 2 mg of zeaxanthin daily does not lower the risk of advanced age-related macular degeneration in adults aged 50–85 who have high-risk drusen.
See the scientific wording
Supplementing with lutein and zeaxanthin (10 mg and 2 mg daily) does not significantly reduce the risk of progression to advanced age-related macular degeneration in adults aged 50–85 with high-risk drusen, as shown by a 5-year randomized trial of 4,203 participants where the hazard ratio was 0.90 (98.7% CI, 0.76–1.07; P = .12) compared to placebo.
When people take lutein and zeaxanthin supplements, these nutrients enter the bloodstream and travel to the back of the eye, where they build up in a protective layer called the macular pigment. This layer blocks harmful blue light and neutralizes damaging molecules produced by light exposure, which should protect the light-sensing cells in the retina. Even though this protection happens, it does not stop the progression of severe eye disease in most people with early signs of damage.
What the research says
1 studyTaking lutein and zeaxanthin pills every day didn't help most older adults with early signs of eye disease avoid getting worse vision over five years. But for people who didn't eat much of these nutrients before, it might have helped a little.
