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 540 mcg of chromate CM-100M (filed by NIH under chromium) is higher than 97% of the 7,825 chromium products that print an amount; 247 list more.
  • Its 360 mg of R-alpha lipoic acid (filed by NIH under alpha lipoic acid) is higher than 93% of the 2,407 alpha lipoic acid products that print an amount; 176 list more.
  • At 1 serving a day, the most its directions give, the label lists 3,000 mcg of vanadium, 1.7 times the adult Tolerable Upper Intake Level.

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.
