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:

  • At 2 servings a day, the most its directions give, the label lists 16 mg of manganese, 1.5 times the adult Tolerable Upper Intake Level.
  • Its 660 mcg of molybdenum is higher than 99% of the 4,390 molybdenum products that print an amount; 52 list more.

The NIH database records 2 servings 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.
