What are Amino Acids?

Amino Acids are the building blocks of muscle protein and essential in the human body. There are 21 amino acids in total, which can be split into two categories essential and non-essential. Essential amino acids cannot be made in the body and therefore must be consumed through the diet. Non-essential and semi-essential amino acids include glutamine, whereby supplementation is common amongst athletes.

BCAA supplements

Branched-chain amino acids (BCAA) are essential amino acids and make up more than 30% of all of the body's proteins. BCAA supplementation is common across both anaerobic and aerobic sports. BCAA supplements can be taken before, during and after a workout.
