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:
- 98% of the 655 products that print an amount of citrulline malate list more than its 0.1 g of citrulline malate (median 3 g).
- 86% of the 628 products that print an amount of fenugreek list more than its 50 mg of fenugreek (median 300 mg).
The Tolerable Upper Intake Level is the most of a nutrient per day, from food, water and supplements together, that is likely to pose no risk for almost all adults (Institute of Medicine, 2011). It does not apply under medical supervision. This page compares labels; it is not medical advice.
