The Science- What Are Amino Acids?


Amino acids are the building blocks of protein are therefore of huge biological importance. They are used in every cell in the body and are involved in a vast number of processes from DNA replication to muscle protein synthesis. These organic compounds are composed primarily of carbon, oxygen, hydrogen and nitrogen. Certain amino acids however have side chains which contain other elements.


There are 20-23 protein-building amino acids. These amino acids are joined together in long chains called polypeptide chains. The polypeptide chains are then joined together to form protein. These amino acids can be subdivided into non-essential and essential amino acids. Non-essential amino acids can be produced by the body. Essential amino acids however must be obtained through food or supplementation as they cannot be synthesised from materials in the body.


Why Might You Use Amino Acids As Part Of A Muscle Building Diet?


When used in conjunction with resistance exercise, amino acids have been shown to support the maintenance, repair and production of muscle tissue. BCAAs (branched chain amino acids) in particular are able to increase the rate of protein synthesis in the body.


Perhaps the most well-known amino acid in sport, L-carnitine can provide the body with a number of benefits. The role of L-carnitine is to transport fat molecules to the mitochondria of cells where they can be used as an energy source. Utilising the body’s fat stores as an energy source will aid athletes trying to achieve a more lean appearance.


L-lysine is an amino acid which plays an essential role in the absorption of calcium in the body. It is therefore an important factor in both bone and muscle growth. Furthermore, L-lysine is involved in the maintenance of lean body mass following extreme stress or fatigue. As a result L-lysine plays an important part in the recovery process for muscle tissue following an intense workout.

Amino Acid Supplementation

Taking into account the fact that amino acids are the building blocks of protein, it is natural to consider consuming an amino acid supplement as part of a muscle building programme. When combined with resistance training, the right amino acid supplementation could enhance muscle protein synthesis, fat loss and also the maintenance of lean body mass.

The Amino Pro Nano Stack by USN would be a good place to start in terms of amino acid supplementation. Its combination of amino acids are tailored to not only support the growth and maintenance of muscle tissue but to also reduce fatigue, allowing for a more intense and successful workout.
