What is in OsoLean Whey Protein Supplement?

Is that a lot?

Every amount on this label with a position sits within the middle 80% of the products that list the same ingredient; 1 ingredient sits inside a blend, so their amounts cannot be compared.

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.
