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:

  • 89% of the 12,413 products that print an amount of niacin list more than its 5 mg of niacin (median 20 mg).
  • 97% of the 6,382 products that print an amount of iodine list more than its 15 mcg of iodine (median 150 mcg).

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.
