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:
- 92% of the 215 products that print an amount of maritime pine list more than its 2.5 mg of pycnogenol (filed by NIH under maritime pine) (median 50 mg).
The NIH database records 3 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.
