  • At 1 serving a day, the most its directions give, the label lists 200 mg of niacin, 5.7 times the adult Tolerable Upper Intake Level.
  • Its 400 mg of pantothenic acid (vitamin B5) is higher than 98% of the 10,060 pantothenic acid (vitamin B5) products that print an amount; 211 list more.

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.
