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:

  • 90% of the 655 products that print an amount of citrulline malate list more than its 0.5 g of L-citrulline malate (filed by NIH under citrulline malate) (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.
