- 91% of the 403 products that print an amount of phosphatidylcholine list more than its 18 mg of phosphatidylcholine (median 120 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.
