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 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.
  • 88% of the 1,850 products that print an amount of glutamine list more than its 0.1 g of L-glutamine (filed by NIH under glutamine) (median 1 g).
  • 95% of the 338 products that print an amount of St. John's wort list more than its 30 mg of St. John's wort (median 300 mg).
  • 89% of the 1,339 products that print an amount of ginkgo list more than its 15 mg of ginkgo (median 60 mg).

The NIH database records one serving 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.
