Postexercise protein-leucine supplementation increases branched-chain amino acid (BCAA) levels in plasma by 2.6-fold and in urine by 2.8-fold.
Supplementing with protein-leucine post-exercise can significantly boost BCAA levels.
StrongSupportsmedium confidence
LEUPRO increased BCAA levels in plasma (2.6-fold; 90% confidence limits = ×/÷ 1.1) and urine (2.8-fold; ×/÷ 1.2).
