A typical 1 tbsp serving of sweet whey powder contains 1 grams of protein (12.9 g per 100 g), which makes it only a minor source of protein. That covers roughly 2% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Around 15% of the calories in sweet whey powder 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 81 dairy foods in the database, sweet whey powder ranks 77th by protein per serving, and 729th out of all 796 foods on the site. Set against half and half, another dairy food entry in the database, a serving carries about 0.5 g more protein (half and half has 0.5 g per 1 tbsp).
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 7.5 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Food-grade sweet whey is mostly lactose, unlike concentrated whey protein powder.
