Is that a lot?

Every amount on this label with a position sits within the middle 80% of the products that list the same ingredient; 6 ingredients sit inside a blend, so their amounts cannot be compared.

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.
