A typical 6 oz container serving of soy yogurt contains 8.2 grams of protein (4.83 g per 100 g), which makes it a good source of protein. That covers roughly 16% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 21% of the calories in soy yogurt 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 31 soy foods in the database, soy yogurt ranks 14th by protein per serving, and 344th out of all 796 foods on the site. Set against meatless deli slices, another soy food entry in the database, a serving carries about 3.2 g more protein (meatless deli slices has 5 g per 1 slice).
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 measured by weight at 170 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
