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 3,000 mg of spirulina (filed by NIH under blue-green algae) is higher than 91% of the 709 blue-green algae products that print an amount; 18 list more.
  • 93% of the 4,607 products that print an amount of vitamin K list more than its 14 mcg of vitamin K (median 80 mcg).
