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:

  • 78% of the 140 products that print an amount of magnesium creatine list more than its 0.5 g of creatine MagnaPower (filed by NIH under magnesium creatine) (median 1 g).
  • Its 1,000 mg of N-acetyl-L-tyrosine (filed by NIH under N-acetyl tyrosine) is higher than 92% of the 344 N-acetyl tyrosine products that print an amount; 1 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.
