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:

  • 70% of the 37 products that print an amount of 5-alpha-hydroxy laxogenin list more than its 20 mg of 5a-hydroxy laxogenin (filed by NIH under 5-alpha-hydroxy laxogenin) (median 25 mg).
