  • 93% of the 530 products that print an amount of broccoli list more than its 15 mg of TrueBroc (filed by NIH under broccoli) (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 directions as printed are further down this page.
