Protein powder is very important for muscle development and recovery, it is made up of a chain of amino acids which help restore and build muscle tissue. Protein can come from different sources and work in different ways, whey protein concentrate and whey protein isolate are very high in protein percentage and are absorbed by the muscles rapidly. Other protein sources include micellar casein and soy protein isolate which are just as effective but are digested by the body and muscles in different ways.
Protein powder can be from an individual source such as whey protein concentrate (WPC 80) or can be built as a blend of numerous different protein sources. Both forms of protein are very beneficial to the body and muscles it is just simply a matter of preference.
