Whey protein is used to help improve and promote the growth of lean muscle mass. Whey protein is considered a complete protein, because it contains all nine of the essential amino acids.
- Whey protein concentrate: contains low levels of fat and carbohydrates
- Whey protein isolate: are processed to remove all of the fat and lactose from the whey. Whey protein isolates are usually 90% protein.
- Whey protein hydrolysate: is considered to be the predigested form of whey protein, because it has already gone through a partial hydrolysis. Whey protein hydrolysate doesn’t require as much digestion as the other two forms of whey.
Taking whey protein is a convenient way to add extra protein to your caloric intake or to use as a meal replacement. Whey protein concentrate is the cheapest of the three different types of protein and it contains more of the beneficial nutrients that the body needs.
