Differences Between Whey Protein & Protein Powder

In the hour following resistance weight training, the consumption of whey protein allows for greater gains in lean muscle mass. (Ref. 1.) Whey protein is typically consumed as a powder mixed with water or milk to create a protein shake.

Whey's Origins

Whey is a liquid by-product of cheese-making. Whey protein is naturally available in milk. (Ref. 2.)

Whey Protein Concentrate

According to the USDA, dry whey protein concentrate is between 25 percent and 89.9 percent protein, and contains no more than 10-percent milk fat. (Ref. 3.)

Whey Protein Isolates

Whey protein isolate contains at least 90 percent protein, and it contains less lactose than whey protein concentrate.

Whey Protein Powders

Protein powders may include whey protein concentrate or whey protein isolate. Powders will also include flavorings for taste and additives that enhance post-workout recovery.

Other Protein Powders

Protein powders can also be based on soy protein. Soy protein is often considered inferior to whey proteins, which are complete proteins. (Ref. 2.)
