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 400 mg of riboflavin is higher than over 99% of the 9,824 riboflavin products that print an amount; 5 list more.
  • At 1 serving a day, the most its directions give, the label lists 360 mg of magnesium, 1 times the adult Tolerable Upper Intake Level.

The Tolerable Upper Intake Level is the most of a nutrient per day, from food, water and supplements together, that is likely to pose no risk for almost all adults (Institute of Medicine, 2011). It does not apply under medical supervision. This page compares labels; it is not medical advice.
