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:
- 97% of the 1,602 products that print an amount of theanine list more than its 20 mg of L-theanine (filed by NIH under theanine) (median 100 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 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.
