  • Its 1,000 mg of vitamin C is higher than 91% of the 18,583 vitamin C products that print an amount; 445 list more.
  • At 1 serving a day, the most its directions give, the label lists 70 mg of niacin, 2 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.
