Amino acids are foundational components of proteins and play a critical role in tissue repair, immune function, and overall recovery processes, making them valuable in supporting convalescence—the recovery phase following illness or surgery. Scientific studies support their use, particularly in the context of malnutrition, post-surgical recovery, trauma, burns, and chronic illnesses where catabolism (breakdown of body tissues) is pronounced. Supplementation with essential amino acids, especially branched-chain amino acids (BCAAs), has been shown to promote muscle protein synthesis, preserve lean body mass, and enhance wound healing. For example, clinical trials in hospitalized and elderly patients have demonstrated that amino acid-enriched nutritional formulas result in improved nitrogen balance, better physical function, and shorter recovery times compared to isocaloric controls without added amino acids.

In addition, guidelines from clinical nutrition societies (such as ESPEN and ASPEN) recommend amino acid supplementation as part of medical nutrition therapy for convalescent patients who are unable to meet protein needs through diet alone. While not every convalescent patient requires supplementation, those with increased metabolic demands or insufficient dietary intake benefit from amino acid support. Thus, the use of amino acids in convalescence is grounded in a strong scientific rationale and moderate-to-high-quality clinical evidence, particularly in vulnerable populations.
