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:
- At 2 servings a day, the most its directions give, the label lists 1,800 mcg of iodine, 1.6 times the adult Tolerable Upper Intake Level.
- 84% of the 106 products that print an amount of spleen list more than its 10 mg of raw porcine spleen (filed by NIH under spleen) (median 45 mg).
The NIH database records 2 servings 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.
