The rows in the top or bottom tenth of the products that list the same ingredient, and any above the adult upper limit at the most servings a day the directions give:

  • 93% of the 2,493 products that print an amount of lutein list more than its 0.2 mg of lutein (median 3 mg).
  • 96% of the 1,691 products that print an amount of lycopene list more than its 0.2 mg of lycopene (median 1.2 mg).
  • over 99% of the 1,215 products that print an amount of zeaxanthin list more than its 0.01 mg of zeaxanthin (median 1 mg).
