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:

  • 97% of the 14,175 products that print an amount of vitamin D list more than its 1.88 mcg (75 IU) of vitamin D (median 15 mcg (600 IU)).
  • Its 250 mcg of vitamin K is higher than 94% of the 4,607 vitamin K products that print an amount; 282 list more.
  • At 2 servings a day, the most its directions give, the label lists 150 mg of niacin, 4.3 times the adult Tolerable Upper Intake Level.
  • At 2 servings a day, the most its directions give, the label lists 15 mg of manganese, 1.4 times the adult Tolerable Upper Intake Level.
  • 97% of the 1,220 products that print an amount of silicon list more than its 0.15 mg of silica (filed by NIH under silicon) (median 4 mg).

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.
