  • At 1 serving a day, the most its directions give, the label lists 250 mg of niacin, 7.1 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.
