Fact Check: "AREDS2 Used 20 mg of Lutein." It Used 10.

We put a red pen to the claims in eye-vitamin ads and checked them against the National Eye Institute. No fake doctor, no "this page expires" timer. Just the numbers, where they come from, and exactly what's in ours.

Eye-vitamin ads tend to look the same: a "board-certified" doctor you can't find anywhere, a teary story, a countdown, and big numbers that sound scientific. The actual numbers are public. Here's how the common claims hold up.

1"AREDS2 used 20 mg of lutein."

✗ It used 10 mg of lutein and 2 mg of zeaxanthin. That's 12 mg combined, per the National Eye Institute's own formula table.1

AREDS2 formula (per NEI) Daily amount
Lutein 10 mg
Zeaxanthin 2 mg
Vitamin C 500 mg
Vitamin E 400 IU (180 mg)
Zinc 80 mg
Copper 2 mg

Source: National Eye Institute, AREDS/AREDS2.1

2"Restores your vision" / "cures" anything.

✗ No eye vitamin should promise that. If an ad says "restore," "reverse" or "cure," close the ad. Ours is made to support macular health and macular pigment as you age, and we won't claim more than that.*

3"15-in-1 beats the AREDS2 formula."

✗ More ingredients isn't the same as better. The AREDS2 formula is six specific nutrients at specific amounts. When the NEI tested adding omega-3 fish oil to it, the addition showed no extra effect.1

4"Recommended by Dr. ___."

✗ If you can't look the doctor up, treat it as an actor. We don't use a doctor in our ads or on this page, because we don't have one to show you. Your own eye doctor is the right person to ask.

Where lutein and zeaxanthin fit

Lutein and zeaxanthin are concentrated in the macula, the center of the retina used for sharp, detailed vision, where they form the yellow "macular pigment" that absorbs blue light. People can't make them, so they have to come from food.2 National survey data put the average U.S. adult at about 1.7 mg a day.2 AREDS2 used 12 mg.1
