Is that a lot?

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:

  • At 4 servings a day, the most its directions give, the label lists 4,268 mg of vitamin C, 2.1 times the adult Tolerable Upper Intake Level.
  • At 4 servings a day, the most its directions give, the label lists 428 mg of magnesium, 1.2 times the adult Tolerable Upper Intake Level.

The NIH database records 4 servings a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.
