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 1 serving a day, the most its directions give, the label lists 125 mcg (5,000 IU) of vitamin D, 1.3 times the adult Tolerable Upper Intake Level.
  • Its 2,100 mcg of vitamin K is higher than 99% of the 4,607 vitamin K products that print an amount; 66 list more.
  • Its 1,000 mcg of iodine is higher than 98% of the 6,382 iodine products that print an amount; 140 list more.

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.

The Tolerable Upper Intake Level is the most of a nutrient per day, from food, water and supplements together, that is likely to pose no risk for almost all adults (Institute of Medicine, 2011). It does not apply under medical supervision. This page compares labels; it is not medical advice.
