Casein, egg or whey. Which is the best protein powder?
Posted in Unexpected on April 20th, 2010The best protein powder for most athletes and body builders comes in the form of casein, egg, and whey. Each different type of protein powder has its own advantages and disadvantages. A careful study of each type is necessary to know which is suitable for you.
-Casein protein: it has biological value of 77. The main advantages of this type of protein powder are the following: highest content of glutamine (among the other type) that can aid in preserving muscle mass and immune system functions, and the body absorbs and use more protein efficiently because it moves slowly to the digestive tract.
-Egg protein: it has biological value of 88. This is the best alternative for those who suffer from allergies to other types of protein powder. Having a higher biological value than casein implies that more amino acids can be used by the body especially for tissue growth. It is free from fat and carbohydrates. Hence, it is low in calories.
-Whey protein: highest biological value among the other types, thus, more amino acids for tissue growth. It is absorbed by the body fast. It strengthens the immune system as well as aids in its function. It increases the production of insulin-like growth factor-1 (IGF-1) for muscle growth. It has great amino acid profiling like the indispensable amino acids and branched chains amino acids.
You may be asking why soy is not included in the list even though it is known to be one of the protein powders. The simple explanation to that is that the other types (casein, egg and whey) have greater and superior effects in many aspects.
