  • At 1 serving a day, the most its directions give, the label lists 60 mg of niacin, 1.7 times the adult Tolerable Upper Intake Level.
  • 88% of the 15,277 products that print an amount of vitamin B6 list more than its 1 mg of vitamin B6 (median 6 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.
