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:
- 95% of the 676 products that print an amount of 5-HTP list more than its 10 mg of L-5-hydroxytryptophan (filed by NIH under 5-HTP) (median 100 mg).
The NIH database records 1 to 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.
