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:

  • 96% of the 14,175 products that print an amount of vitamin D list more than its 2 mcg (80 IU) of vitamin D (median 15 mcg (600 IU)).
  • At 1 serving a day, the most its directions give, the label lists 50 mg of niacin, 1.4 times the adult Tolerable Upper Intake Level.
  • At 1 serving a day, the most its directions give, the label lists 12 mg of manganese, 1.1 times the adult Tolerable Upper Intake Level.

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.
