Most eye-health supplements underdose the two ingredients they lead with. Here's what to check on the label.
A popular claim with a thinner research base than the marketing suggests.

We flag fat-soluble vitamins and zinc levels that run close to or above daily upper limits.
We note whether an independent lab has verified the product's contents.
