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:

  • 89% of the 1,680 products that print an amount of tyrosine list more than its 50 mg of L-tyrosine (filed by NIH under tyrosine) (median 500 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.
