  • Its 100 mg of vitamin B6 is higher than 96% of the 15,277 vitamin B6 products that print an amount; 173 list more.
  • 94% of the 7,658 products that print an amount of selenium list more than its 10 mcg of selenium (median 55 mcg).

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.
