- Its 1,000 mg of L-tryptophan (filed by NIH under tryptophan) is higher than 92% of the 605 tryptophan products that print an amount; 20 list more.
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.
