Amino acids are the building blocks of proteins. They are organic compounds that contain both an amino group (-NH2) and a carboxyl group (-COOH) and are essential for many functions in the body. There are 20 different amino acids that can be used to make proteins, out of which 9 are considered essential, meaning that they cannot be produced by the body and must be obtained through diet.
Amino acids play several important roles in good health:
- Building and repairing muscle tissue: Amino acids are essential for the growth, repair and maintenance of muscle tissue.
- Supporting the immune system: Some amino acids are important for the proper functioning of the immune system, including arginine, glutamine and cysteine.
- Supporting brain function: Some amino acids, such as tryptophan, are important for the production of neurotransmitters, which are chemicals that help transmit signals in the brain.
- Regulating metabolism: Some amino acids, such as branched-chain amino acids (BCAAs), help regulate metabolism by promoting muscle growth and reducing muscle breakdown.
- Promoting healthy skin, hair and nails: Some amino acids, such as cysteine, help promote healthy skin, hair and nails.
- Promoting healthy digestion: Some amino acids, such as glutamine, help promote healthy digestion.
- Helping to balance hormones: Some amino acids, such as arginine and lysine, help balance hormones.
- Helping to reduce inflammation: Some amino acids, such as glutamine and cysteine, help reduce inflammation.
It’s important to note that, while amino acids are important for good health, having too much of certain amino acids can have negative effects, and not all amino acids are equally beneficial for everyone. It’s important to consult a healthcare professional before starting to take any amino acid supplements.
