Amino acids

Amino acids: what they are and what they are for

Amino acids are the building blocks that make up proteins. Some of them, called essential, cannot be produced by the body and must be obtained through diet or supplementation. This is why amino acid supplements are very popular among people who play sports and want to support their protein requirements.

Types of amino acids

  • BCAA (branched-chain amino acids): leucine, isoleucine and valine, among the most used in sport.
  • EAA (essential amino acids): the complete set of amino acids the body does not synthesise on its own.
  • Specific amino acids: such as glutamine, arginine and others, chosen according to goals and preferences.

When to take amino acids

Amino acids can be taken at different times, for example before, during or after training, depending on your goals and type of activity. They are available in various forms, such as powder, tablets and capsules, to suit everyone's needs.

Choose your amino acids at Citymuscle

At Citymuscle you will find a wide selection of amino acids from the best brands, along with a complete range of food supplements and sportswear to support your training.

Food supplements are not intended to replace a varied, balanced diet and a healthy lifestyle. Do not exceed the recommended daily dose.
