A typical 2 tbsp serving of goji berries contains 1.6 grams of protein (14.3 g per 100 g), which makes it only a minor source of protein. That covers roughly 3% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 16% of the calories in goji berries come from protein, so it is more of an energy food than a protein food. 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 71 fruits in the database, goji berries ranks 15th by protein per serving, and 681st out of all 796 foods on the site. Set against dried apricots, another fruit entry in the database, a serving carries about 0.5 g more protein (dried apricots has 1.1 g per 1/4 cup).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving above is measured by volume at 11.2 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Among the most protein-dense dried fruits, though it is normally eaten by the spoonful rather than the cup.
