A typical 1 cup serving of whole milk powder contains 33.7 grams of protein (26.3 g per 100 g), which makes it an excellent source of protein. That covers roughly 67% of the 50 g reference Daily Value, so it can anchor a high-protein meal for the day.
Around 21% of the calories in whole milk powder 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, whole milk powder ranks 2nd by protein per serving, and 3rd out of all 796 foods on the site. Set against cottage cheese (1%), another dairy food entry in the database, a serving carries about 5.7 g more protein (cottage cheese (1%) has 28 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 128 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Measured as dry powder before reconstituting with water.
