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:
- 91% of the 1,209 products that print an amount of citrulline list more than its 0.25 g of L-citrulline (filed by NIH under citrulline) (median 3 g).
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.
