Rating (out of 5): 4

Branched-chain amino acids (BCAAs)—leucine, isoleucine, and valine—are used in clinical settings to support liver detoxification, particularly in patients with chronic liver disease such as cirrhosis or hepatic encephalopathy. The scientific rationale is based on the altered metabolism of amino acids that occurs in liver dysfunction. Patients with advanced liver disease often have decreased levels of BCAAs and increased aromatic amino acids, contributing to the development of hepatic encephalopathy, a neuropsychiatric complication. Supplementation with BCAAs helps restore the balance of amino acids, supporting muscle protein synthesis and providing an alternative substrate for ammonia detoxification, as BCAAs are metabolized primarily in skeletal muscle rather than the liver.

Multiple randomized controlled trials and meta-analyses have demonstrated that BCAA supplementation can improve outcomes in liver disease by reducing the frequency and severity of hepatic encephalopathy, improving nutritional status, and, in some cases, enhancing quality of life. BCAAs are part of standard medical nutrition therapy for managing complications of liver failure in Japan and increasingly elsewhere. However, while BCAAs are beneficial in specific complications related to liver dysfunction, there is less evidence supporting their use for general “liver detoxification” in healthy individuals. Thus, BCAAs are scientifically validated for supportive care in liver disease rather than as a general detoxifying agent.
