Essential Amino Acids
Exogenous amino acids are those that our body cannot synthesize on its own and must be supplied from the outside, i.e. through food. There are eight basic exogenous amino acids that are necessary for the proper functioning of the body.
Key functions of exogenous amino acids
Exogenous amino acids perform many important functions in the body. They are not only the building blocks of proteins, but also play a role in the synthesis of hormones, enzymes and neurotransmitters. In addition, exogenous amino acids support the processes of tissue regeneration and growth, maintain nitrogen balance and support the immune system.
Sources of exogenous amino acids in the diet
- Meat, fish and poultry
- Eggs
- Dairy products such as milk, yogurt and cheese
- Legumes such as beans, lentils and chickpeas
- Nuts and seeds
- Dietary supplements
Benefits of consuming exogenous amino acids
- Supporting muscle growth and regeneration.
- Improving the functioning of the immune system.
- Maintaining nitrogen balance in the body.
- Supporting metabolic processes.
- Regulation of blood sugar levels.
- Strengthening bone and joint health.
What are the most important exogenous amino acids?
Leucine: Plays a key role in muscle protein synthesis and supports muscle regeneration after training.
Isoleucine: Supports energy metabolism and regulates blood sugar levels.
Valine: Takes part in protein synthesis processes and helps maintain the proper functioning of the nervous system.
Lysine: It is necessary for the construction of collagen, which is the basic component of connective tissues.
Methionine: Supports detoxification of the body and is a key ingredient for the production of glutathione, an important antioxidant.
Phenylalanine: Acts as a precursor of important neurotransmitters such as dopamine and norepinephrine.
Threonine: It affects the functioning of the immune system and is necessary for proper fat metabolism.
Tryptophan: It is a precursor of serotonin, a hormone responsible for regulating mood and sleep.
Dosage of exogenous amino acids
The dosage of exogenous amino acids depends on the individual needs of the body, physical activity and training goals. There are various dietary supplements containing exogenous amino acids, such as BCAAs (branched chain amino acids) or EAA complex amino acid mixtures.
Potential effects of exogenous amino acid deficiency
Deficiency of exogenous amino acids can lead to various health problems. Inadequate intake of exogenous amino acids can lead to loss of muscle mass, weakened immune system, delayed wound healing, mood disorders and lack of energy. Therefore, it is important to provide your body with enough of these essential nutrients through a balanced diet.
Is supplementation with exogenous amino acids safe?
Exogenous amino acid supplementation may be safe when used as directed and not exceeding recommended doses. However, you should always remember that dietary supplements should be treated as a complement to a balanced diet, and not as a replacement for proper nutrition. People with certain medical conditions or taking certain medications should consult a doctor before starting supplementation.
