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:

  • Its 3,000 mg of trimethylglycine (filed by NIH under betaine) is higher than 97% of the 731 betaine products that print an amount; 10 list more.

The NIH database records 2 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.
