  • 86% of the 311 products that print an amount of coconut list more than its 100 mg of cococin coconut water powder (filed by NIH under coconut) (median 500 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.
