Rating (out of 5): 3

Amino acids are the building blocks of proteins and are commonly used in clinical nutrition to support individuals with poor protein digestion. The scientific rationale for their use in this context is based on the understanding that when protein digestion is compromised—due to conditions such as pancreatic insufficiency, gastrointestinal surgery, or severe illness—the body may not adequately break down dietary proteins into absorbable amino acids and peptides. Supplementing with free-form amino acids or protein hydrolysates can bypass some aspects of digestive impairment, allowing direct absorption in the small intestine. Clinical studies have shown that amino acid supplementation can help maintain nitrogen balance, muscle mass, and overall nutritional status in patients with malabsorption syndromes or reduced digestive capacity. For example, research in patients with chronic pancreatitis or short bowel syndrome has demonstrated improved nutritional markers and reduced symptoms when amino acids are provided in easily absorbable forms. However, the evidence is stronger in clinical nutrition and hospital settings than for routine use in otherwise healthy individuals with mild digestive complaints. Most over-the-counter amino acid supplements are marketed for sports or general wellness rather than specifically for poor protein digestion. Overall, while there is scientific support—especially in specific medical contexts—the general evidence base is moderate, not robust, and should be tailored to individual medical needs.
