Essential amino acids are the building blocks of proteins that the body cannot synthesize, so it is necessary to obtain them through a balanced diet. Naturally, it is also possible to supplement dietary intake with nutritional supplements. They are essential for muscle building and muscle regeneration, but also for the proper functioning of the immune system and metabolism, as well as for mental performance.
Amino acid supplementation is common, whether in the form of BCAAs or full-spectrum preparations (EAAs), among athletes or as part of a diet when protein intake is insufficient or of incomplete quality.
