Amino acids are the building blocks of life. They play a crucial role in numerous biochemical processes in the human body. From protein synthesis to the regulation of metabolism, they are indispensable for optimal health and function of the body.

What are amino acids?

Amino acids are organic compounds consisting of carbon, hydrogen, oxygen and nitrogen. They are the basic building blocks of proteins, which are responsible for the formation and repair of tissues in the body. Of the total of twenty amino acids, nine are considered essential, as the body cannot produce them itself and they must therefore be obtained from food.

The role of amino acids in the body

  1. Protein synthesis: They are crucial for protein synthesis, the process by which proteins are made in cells. Without sufficient amounts, the body cannot produce new proteins, which can lead to deficiencies in important tissues and enzymes.
  2. Energy production: Some serve as a source of energy for the body, especially during intense physical activity or times of nutrient deficiency. They can be converted into glucose to maintain the body’s energy supply.
  3. Immune function: Certain amino acids, such as glutamine, play an important role in supporting the immune system. They help maintain the integrity of the intestinal mucosa and thus contribute to the defense against pathogens.

Benefits of taking amino acids for humans

The targeted intake can provide numerous health benefits, including:

  1. Muscle growth and recovery: Branched-chain amino acids (BCAAs) in particular, such as leucine, isoleucine and valine, are essential for building and repairing muscle tissue. Athletes and fitness enthusiasts often use amino acid supplements to speed up muscle recovery after training and promote muscle growth.
  2. Healthy skin, hair and nails: Collagen plays a key role in maintaining the structural integrity of skin, hair and nails. Taking collagen supplements can help improve skin elasticity and reduce the appearance of wrinkles and other age-related skin problems.
  3. Mood regulation: Tryptophan and tyrosine, are precursors of neurotransmitters such as serotonin and dopamine, which play an important role in regulating mood and emotional well-being. Taking them can therefore help to stabilize mood swings and alleviate depressive symptoms.

Amino acids for certain diseases

The targeted intake of amino acids can also be beneficial in the treatment and prevention of certain conditions, including

  1. Muscle wasting and sarcopenia: Older people are often affected by muscle wasting and sarcopenia, which can lead to an increased risk of falls, injuries and a reduced quality of life. Taking amino acid supplements, especially BCAAs, can help maintain muscle mass and strength and slow down age-related muscle loss.
  2. Wound healing and tissue regeneration: It play a crucial role in wound healing and tissue regeneration after injuries or operations. The targeted intake of amino acids can accelerate the healing processes and support the formation of new tissue.
  3. Inflammatory bowel disease (IBD): People with inflammatory bowel diseases such as Crohn’s disease or ulcerative colitis can benefit from taking amino acid supplements. It can help to soothe the inflamed tissues in the intestine and support the regeneration of the intestinal mucosa.

Combination with other food supplements

The effect of amino acids can be enhanced by combining them with other supplements. Some recommended combinations are:

  1. Vitamin D and calcium: Vitamin D and calcium are essential for bone health and can support the effects in maintaining muscle mass and strength.
  2. Omega-3 fatty acids: Omega-3 fatty acids have anti-inflammatory properties and can enhance the anti-inflammatory effects in the treatment of inflammatory diseases such as IBD.
  3. Antioxidants: Antioxidants such as vitamin C and vitamin E can reduce cell damage from free radicals and support tissue regeneration, which may enhance the effect of amino acids in healing wounds and maintaining skin health.


Amino acids are crucial for optimal health and function of the human body. Their targeted intake can support muscle growth and repair, improve skin health, regulate mood and promote tissue healing. They can play an important role in the treatment and prevention of certain conditions such as muscle wasting, wound healing problems and inflammatory bowel disease.

Combining amino acids with other supplements such as vitamins, minerals and antioxidants can further optimize the health benefits and help the body cope with disease.

Overall, amino acids are essential nutrients that fulfill a diverse range of functions in the body. By eating a balanced diet and supplementing with amino acid supplements where appropriate, people can improve their health and quality of life. However, it is important to consult a doctor before taking supplements to ensure that they are suitable for individual needs.
