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 2 servings a day, the most its directions give, the label lists 400 mg of magnesium, 1.1 times the adult Tolerable Upper Intake Level.
  • 94% of the 1,990 products that print an amount of fish oil list more than its 0.33 g of norwegian fish oil concentrate (filed by NIH under fish oil) (median 1.2 g).

The NIH database records 2 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.

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.
