The amount of protein in a scoop of whey protein powder can vary depending on the specific brand, type, and serving size. However, a typical serving size for whey protein powder is about 30 grams, which is roughly equivalent to one scoop. The protein content per scoop generally ranges from 20 to 25 grams. This variation is influenced by the type of whey protein and any additional ingredients included in the product.
Whey protein concentrate typically contains between 70% to 80% protein by weight. A typical 30-gram scoop of whey protein concentrate can provide approximately 20 to 24 grams of protein. The remaining content includes fats, carbohydrates, and lactose1.
Whey protein isolate is more processed than concentrate, resulting in a higher protein content—usually around 90% or more by weight. A typical 30-gram scoop of whey protein isolate can provide approximately 25 to 27 grams of protein. It contains minimal fats and carbohydrates, making it a popular choice for those looking to increase protein intake without additional calories2.
Whey protein hydrolysate is a pre-digested form of whey, allowing for faster absorption. It usually contains a similar protein content to whey protein isolate, with around 25 to 27 grams of protein per 30-gram scoop. This type of whey protein is often used in clinical and athletic settings due to its rapid absorption and reduced potential for allergic reactions3.
