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:

  • Its 150 mg of TeaCrine theacrine (filed by NIH under theacrine) is higher than 90% of the 237 theacrine products that print an amount; 18 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.
