A typical 1 link serving of italian sausage contains 13.7 grams of protein (18.2 g per 100 g), which makes it a good source of protein. That covers roughly 27% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 23% of the calories in italian sausage 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.
Among the 133 meats in the database, italian sausage ranks 104th by protein per serving, and 266th out of all 796 foods on the site. Set against deli turkey slices, another meat entry in the database, a serving carries about 1.5 g more protein (deli turkey slices has 12.2 g per 2 slices).
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 above is counted by piece at 75 g. Because pieces vary, the per-100 g figure is the one to use when comparing this against a food measured a different way.
