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:

  • 97% of the 14,175 products that print an amount of vitamin D list more than its 1.88 mcg (75 IU) of vitamin D (median 15 mcg (600 IU)).
  • At 1 serving a day, the most its directions give, the label lists 450 mg of magnesium, 1.3 times the adult Tolerable Upper Intake Level.

The NIH database records one serving 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.
