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.
  • 79% of the 1,602 products that print an amount of theanine list more than its 50 mg of L-theanine (filed by NIH under theanine) (median 100 mg).
  • 85% of the 344 products that print an amount of N-acetyl tyrosine list more than its 50 mg of N-acetyl L-tyrosine (filed by NIH under N-acetyl tyrosine) (median 250 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.
