Every 100 kcal of blue cheese brings 6.1 g of protein. On that measure it ranks 44th of the 81 dairy foods in this database and 405th of all 796 foods on the site. Measured by weight instead, its 21.4 g per 100 g ranks 30th in its group.
Around 24% of the calories in blue cheese come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
By weight, fat outweighs protein in blue cheese: 28.7 g of fat per 100 g against 21.4 g of protein, a ratio of 0.7 to 1.
Set against drinkable yogurt, another dairy food entry in the database, a serving carries about 0.5 g more protein (drinkable yogurt has 5.5 g per 1 bottle).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving quoted here is measured by weight at 28 g, and it covers about 12% of the 50 g FDA Daily Value for protein.

Sample figures for one made-up week against a 110 g goal, not your data. Red bars met the goal. Your own log fills this in with Premium.
21.4 g. The 1 oz serving used on this page weighs 28 g and so carries 6 g.
How much protein do you get per 100 calories of blue cheese?
6.1 g. That figure divides its 21.4 g of protein per 100 g by its 353 kcal per 100 g, so it does not depend on serving size.
Is the protein in blue cheese complete?
Yes. The protein in blue cheese supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own.
What share of the protein Daily Value is one serving of blue cheese?
About 12%. One 1 oz serving has 6 g, and the FDA Daily Value for protein is 50 g.
