Amino Acids make up protein.
Protein makes up basically everything in your body.
In fact the only thing our body has more of than protein is water. 
 
It really is as simple as that. Protein is the building block of our whole body - muscles, tissues, hair, nails, etc - all made up of protein. If you do not have enough protein in your body you can NOT build muscle mass. The body needs to break protein down to amino acids to build muscles. So, no matter how much you work out - if you don't have protein - you will not gain muscle mass.  
 
Another important point to remember is that every time you work out you are tearing down muscles and then rebuilding them. Protein is necessary to repair and rebuild your muscles. 
 
What types of foods have protein?  
 
Protein is found in common foods such as beef, fish, chicken, milk, eggs and cheese. Eating a diet rich in these foods is a good way to get protein. Unfortunately it can also be a good way to increase a lot of other things you don't want in your body like fats and sugars.

What is Whey Protein and why is it good?  
 
Whey Protein is derived from milk protein. However, unlike milk proteins - whey protein does not contain fat or lactose sugar. Whey protein is the best form of protein to take when using a supplement. Basically with Whey Protein you get all the advantages of protein without the excess baggage other proteins come with - no fat and no lactose. Not only that, studies have shown that Whey Protein can increase our blood levels of glutathione. Glutathione is an antioxidant which is essential to a healthy immune system. As we get older glutathione levels decrease and our immune system weakens. Studies are still being done - but at the University of Nebraska Medical center they were able to extend the life span of hamsters by 60% by supplementing their diet with Whey Protein. So, whey protein is not only good for building and repairing muscles, it also may extend your life.  
 
What are the reasons I should supplement with whey protein?  
 
* To build muscle mass
* To speed recovery time
* Reduce injuries related to working out
* Maintain a healthy and fit body
* Feel better during your workouts 
 
Will taking protein make me fat?  
 
No - in fact it may help you if you are on a diet. You see the amino acids in protein may help keep your blood sugar levels stabile. This is important because it keeps you feeling good all day and stops your craving for food that occurs when your blood sugar level drops. If your diet is too high in carbohydrates your blood sugar levels go though peaks and valleys. You go from a burst of energy and feeling full to a lull and being hungry. In addition, if you are dieting, getting 17 grams of protein from a protein shake that has only 90 calories is better than getting your protein from a big meal which may have hundreds of calories.
