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; 10 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.
