- 92% of the 14,175 products that print an amount of vitamin D list more than its 2.5 mcg (100 IU) of vitamin D (median 15 mcg (600 IU)).
- At 2 servings a day, the most its directions give, the label lists 600 mg of magnesium, 1.7 times the adult Tolerable Upper Intake Level.
- 86% of the 7,016 products that print an amount of manganese list more than its 0.5 mg of manganese (median 2 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.
