Dried sweet whey is a powdered milk product made by removing water from the liquid left after cheese-making. It is used as a commercial food ingredient and is not the same as whey protein concentrate or isolate. Per 100g, it provides 78g carbohydrate, all recorded as sugars, 12g protein and 790mg calcium.
Calcium helps maintain bones and teeth, while protein supports tissue growth and repair. The sugars in sweet whey are mainly lactose, which may cause digestive symptoms in people with lactose intolerance. Its salt content is 2.7g per 100g, which is worth noting when monitoring salt intake. The amount used in a food affects its contribution to overall intake. Full nutrient figures are in the tables below.

About these figures
Values are per 100g of the food as described (Commercial ingredient, sweet whey, literature sources). "Trace" means only a very small amount was found. Nutrients that were not measured are not shown. Salt is calculated from sodium.
These figures come from an older part of the dataset that is no longer updated. Original source: Milk Products and Eggs Supplement, 1989.
