Significance

• Protein is the building block of muscle. It is also responsible for immunity, cell function and healthy hair, nails and skin.
  
  

Function

• Whey protein is taken in powder form. It supplements the diet if you are deficient. It is also used by bodybuilders who are on high-protein diets.
  
  

Post-Workout

• Whey protein is often used in a post-workout shake to help repair muscle. It has a high bioavailability, so it gets digested easily by the system.
  
  

Satiety

• Supplementing with whey protein can help keep you feeling full longer. This will keep you from eating too much later in the day.
  
  

Metabolism

• It takes the body more work to break down whey protein than it does carbohydrates, which is called the "thermic effect" of food.
  
  

Complete

• Whey protein contains all the essential amino acids. This makes it a complete protein. Some forms of protein need to be taken with other proteins to make them complete.
  
  

Blood Sugar

• Eating whey protein can help slow the release of blood sugar in the system. This is especially beneficial for diabetics.
