Amino Acids

Amino acids are the building blocks of protein, they are essential to the human body because they aid in repair, growth, and development of muscle tissue. The body, through assimilation of amino acids, produces over 50,000 proteins and over 15,000 enzymes. Amino acids are not only responsible for the production of all the body's enzymes (including digestive enzymes), but they also play a key role in normalizing moods, concentration, aggression, attention, and sleep.
