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 3 servings a day, the most its directions give, the label lists 3,000 mg of calcium, 1.2 times the adult Tolerable Upper Intake Level.
