The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).

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 1 serving a day, the most its directions give, the label lists 45 mg of niacin, 1.3 times the adult Tolerable Upper Intake Level.
  • Its 300 mg of pantothenic acid (vitamin B5) is higher than 97% of the 10,060 pantothenic acid (vitamin B5) products that print an amount; 249 list more.
  • 98% of the 66 products that print an amount of bergamot orange list more than its 6 mg of bergamot [fruit] oil (filed by NIH under bergamot orange) (median 500 mg).

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.

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.
