What is in Single Day?

Each row as the label prints it, per serving of 1 tablet. The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).

Is that a lot?

The rows in the top or bottom tenth of the products that list the same ingredient, and any above the adult upper limit at the most servings a day the directions give:

  • Its 75 mg of vitamin B1 (filed by NIH under thiamin) is higher than 92% of the 9,830 thiamin products that print an amount; 663 list more.
  • Its 75 mg of vitamin B2 (filed by NIH under riboflavin) is higher than 94% of the 9,824 riboflavin products that print an amount; 486 list more.

  • Its 75 mg of vitamin B6 is higher than 94% of the 15,277 vitamin B6 products that print an amount; 715 list more.

  • 99% of the 6,468 products that print an amount of copper list more than its 0.025 mg of copper (median 1 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.

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.
