EAA are essential amino acids - they are essential for human health, but our body cannot produce them, so we need to take them through diet or supplements. EAA includes 9 amino acids - histidine, lysine, methionine, phenylalanine, threonine, tryptophan and BCAAs, also known as leucine, isoleucine and valine.

Each of them plays an important role in the human body:

Histidine - supports growth, blood cell formation and tissue repair. Our body metabolizes it to histamine, which is essential for immunity, reproductive health and digestion.

Lysine - plays a key role in building muscle, maintaining bone strength and regenerating injuries. It also regulates the production of hormones, antibodies and enzymes in the body, but it is also needed for immune function and collagen production in the body.

Methionine - is together with cysteine important for the health of the skin and hair. It also helps to maintain strong nails and supports the proper absorption of selenium and zinc.

Phenylalanine - helps the body to use other amino acids, proteins and enzymes. In the body, it is converted into tyrosine, which is essential for proper brain function. It is also a precursor of dopamine, epinephrine and norepinephrine.

Threonine - is essential for healthy skin and teeth, helps with fat metabolism and can also be helpful for people with digestion problems, anxiety and mild depression.


Tryptophan - is essential for proper growth of infants and produces serotonin and melatonin. Serotonin, like melatonin, regulates sleep, but also appetite, mood and pain.

Leucine - is important in protein synthesis, while supporting the growth and regeneration of muscles and bones. It also regulates blood sugar levels, promotes wound healing and growth hormone production.

Isoleucine - helps in wound healing, supports immunity and regulates blood sugar levels.

Valine - is important not only for mental health and emotional peace, but also to support muscle growth and regeneration.
