Branched chain amino acids also known as BCAAs are critical for protein synthesis to ensure the growth of lean muscle mass and muscle maintenance. Before training increasing endurance, after hard effort to speed up recovery time, BCAAs are especially useful in the case of long endurance sports where a continuous workload on the muscles are required and therefore require a greater amount of nutrients to restore the right balance. The essential amino acids in tablet form are very convenient to dose and are spread in different ratios to suit every needs, from the classic 2: 1: 1 with the most "extreme" 8: 1: 1 to further speed up the recovery time. To offer additional support to the body there are products based on amino acids and complete vitamins and non-essential amino acids, are however very useful for the body.
