The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).

  • Its 1,500 mg of maitake (grifola frondosa) fruiting body powder (filed by NIH under maitake mushroom) is higher than 97% of the 327 maitake mushroom products that print an amount; 6 list more.

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.
