摘要

We comment on Sunsandee et al.'s RCT of leucine-enriched BCAA supplementation in elderly CKD patients. Despite a modest muscle gain, methodological and practical limitations—including unbalanced BCAA formulation, insensitive functional tests, lack of subgroup analysis, and high pill burden—undermine generalizability. Recommendations for future studies are discussed.
