Whey Protein — Frequently Asked Questions
Whey protein is a full and high quality protein derived out of milk and is composed of all the nine essential amino acids. It is widely administered as an aid to muscle build, muscle recovery, weight monitoring, and well-being.
The three main types are:
- Whey Protein Concentrate (WPC)
- Whey Protein Isolate (WPI)
- Hydrolyzed Whey Protein (HWP)
They all vary in protein purity, lactose level and rate of digestio
Whey concentrate is higher in protein (70-80%) with a little fat and lactose thus it is cheaper. Whey isolate is 90% or more protein and most of the fat and lactose are eliminated thus it is best in low fat diets and people who are lactose intolerant.
Whey protein isolate is best suited to people allergic to lactose, on a low-carb or low-fat diet or those who require more protein content per serving.
Hydrolyzed whey protein is digested in advance so that it is absorbed faster. It is commonly used in quick recovery after the workout however, it is more costly.
The whey protein contains a considerable quantity of essential amino acids, especially the BCAAs such as leucine, which promote protein synthesis in the muscles and muscle tissue recovery during exercise.
