Can a simple amino acid drink help elderly COPD patients keep muscle?
NCT ID NCT01173354
First seen Nov 01, 2025 · Last updated Jun 19, 2026 · Updated 30 times
Summary
This study tested whether a special essential amino acid supplement (high in leucine) could help elderly patients with COPD build muscle protein better than a standard amino acid mixture. Thirty-four participants received a one-time dose of either supplement, and researchers measured changes in protein synthesis and breakdown. The goal was to see if targeting specific metabolic issues could improve muscle health in COPD.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
essential amino acid mixture (high leucine)
What this could lead to
If it works, this could point toward a nutritional supplement to help prevent muscle loss in elderly COPD patients.
What could go wrong
This is a very small, early study (34 people) looking only at short-term effects. It does not test long-term benefits or safety, so results may not lead to a practical treatment.
