Roll Call does not check drug interactions or assess personal safety.
A yellow pigment (carotenoid) found in leafy greens, egg yolks, and some fruits, and concentrated in the macula of the eye.
Why it’s used
Taken to support eye health, particularly macular pigment density.
What the evidence is for
slowing progression of age-related macular degeneration in people with existing intermediate disease.
What the evidence says
The AREDS2 trial found that a supplement formula containing lutein and zeaxanthin performed comparably to one containing beta-carotene in slowing progression of age-related macular degeneration in people who already had intermediate-stage disease. Evidence for benefit in people without existing eye disease is much less established.
Dose studied
10–10 mg — AREDS2 trial dose of lutein, paired with 2 mg zeaxanthin.
Context
The AREDS2 formula studied about 10 mg lutein with 2 mg zeaxanthin daily, in an older population already showing signs of macular degeneration; results may not generalize to younger or disease-free populations.
