Leucine-enriched whey protein supplementation (20g whey + 3g leucine) post-exercise does not provide additional benefits for sarcopenia, muscle mass, or myokine concentrations compared to resistance training alone in post-hospitalized older adults over 12 weeks.
You do not need to buy leucine-enriched protein supplements to support your resistance training. The study shows that taking 20g of whey protein with 3g of leucine after training did not improve muscle mass or sarcopenia outcomes more than training alone. Save your money and focus on consistent training.
The main finding of the current study is that the addition of leucine-enriched whey protein to the resistance training program did not cause any significant improvement to frailty and sarcopenia status.
Why this rating
RCT design, but small sample size and short duration limit statistical power to detect subtle differences.

- Twelve weeks of supervised resistance training significantly improves physical performance and reduces frailty prevalence in post-hospitalized older adults, regardless of whether leucine-enriched whey protein is consumed post-exercise.Moderate
- Increases in serum myostatin concentrations following resistance training are positively associated with gains in appendicular skeletal muscle mass in older adults, challenging the view that myostatin solely inhibits muscle growth.Limited
