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:

  • 92% of the 14,175 products that print an amount of vitamin D list more than its 2.5 mcg (100 IU) of vitamin D (median 15 mcg (600 IU)).
  • At 1 serving a day, the most its directions give, the label lists 40 mg of niacin, 1.1 times the adult Tolerable Upper Intake Level.
  • 93% of the 11,614 products that print an amount of potassium list more than its 10 mg of potassium (median 99 mg).
  • 91% of the 4,738 products that print an amount of choline list more than its 5 mg of choline (median 40 mg).
  • 85% of the 1,610 products that print an amount of PABA list more than its 5 mg of paba (filed by NIH under PABA) (median 25 mg).

The NIH database records one serving a day from the label's directions; its % Daily Values are for pregnant and lactating. 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.
