The actual protein value expressed in grams is always required on the Nutrition Facts label and is the same value used when calling out the grams of protein elsewhere on the label.
The adjusted protein amount is only used to calculate the % Daily Value for protein. When making a protein claim including a callout elsewhere on the label, the % Daily Value for protein is required on the Nutrition Facts label. As an example, a black bean soup may declare 10g of protein per serving on the Nutrition Facts label, whereas the adjusted protein amount of 5g is only used in the calculation of % Daily Value. The adjusted amount (5g in this case) does not appear on the label at all.
