Amino 1500 from NOW Foods:

Aids In The Repair, Growth, And Development Of Muscle Tissue!

Amino acids are essential to the human body. Bodybuilders can especially benefit from supplementing amino acids 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, sleep, and sex drive. Scientists, experts, and medical professionals agree that getting enough amino acids in one's diet is an important factor in maintaining good nutrition.
