Muscle loss in cirrhosis: could a simple amino acid drink be the answer?
NCT ID NCT03208868
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This study tests whether a leucine-enriched essential amino acid mixture can reverse muscle loss (sarcopenia) in people with liver cirrhosis. Researchers will give 32 participants either the active mixture or a placebo for 3 months, measuring muscle protein production and overall muscle mass. The goal is to find a safe, effective treatment to improve strength and reduce complications before and after liver transplant.
