Amino acid drink may fight muscle loss in lung cancer patients
NCT ID NCT01172314
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a nutritional supplement with essential amino acids could help lung cancer patients who are losing weight build more protein in their bodies. 41 patients with advanced non-small cell lung cancer took part. The goal was to see if this supplement could reduce muscle breakdown and improve how the body uses protein.
