Every protein in your body is in a constant state of breakdown and synthesis.

It is this balance between the rate of breakdown and the synthesis of a protein that determines whether you are gaining or losing protein. 

You drink water dialy to meet your body's daily need for water. If not you really should start. Similarly, your body also needs amino acids on a daily basis to offset what your body uses, discards or loses.

By eating sufficient essential amino acids, which is best accomplished through a balanced approach (food plus essential amino acid complex - MyoHealth) the rate of protein synthesis can match or even exceed the rate of protein breakdown.

At that point, you have growth, strength, and restored vitality that leads to greater quality of life as well as a reduction in risk of disease. 

It is simply essential that you get all your essential amino acids!
