The Claim
Supplementing with omega-3 fatty acids (DHA 350 mg and EPA 650 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 omega-3 supplements at a dose of 350 mg DHA and 650 mg EPA 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 omega-3 fatty acids (DHA 350 mg and EPA 650 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 0.97 (98.7% CI, 0.82–1.16; P = .70) compared to placebo.
Taking omega-3 supplements increases omega-3 fats in the blood, which go to the back of the eye and get built into the light-sensing cells. These fats help keep the cells flexible and reduce inflammation, but in people with early signs of eye disease, this change does not stop the cells from breaking down over time.
What the research says
1 studyTaking daily omega-3 supplements for five years didn't help older adults with early signs of eye disease avoid getting worse vision, according to a big, careful study. The supplements didn't make a noticeable difference compared to taking nothing.
