A typical 1 cup serving of strawberry kefir contains 8.4 grams of protein (3.39 g per 100 g), which makes it a good source of protein. That covers roughly 17% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 22% of the calories in strawberry kefir 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 81 dairy foods in the database, strawberry kefir ranks 23rd by protein per serving, and 338th out of all 796 foods on the site. Set against chocolate milk, another dairy food entry in the database, a serving carries about 0.5 g more protein (chocolate milk has 7.9 g per 1 cup).
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 volume at 247 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
