Supplemental protein hydrolysate had a positive effect on fat-free mass (FFM) with a standardized mean difference (SMD) of 0.36 (95% CI: 0.16–0.56, P = 0.000).
Practitioners may consider recommending protein hydrolysate supplementation to enhance fat-free mass in resistance-trained individuals.
StrongSupportsmedium confidence
Data from 330 participants in eight studies showed that supplemental protein hydrolysate had a positive effect on the FFM (n = 13, SMD = 0.36, 95% confidence interval (CI): 0.16–0.56, P = 0.000).
Why this rating
Based on the meta-analysis of multiple studies.

- Athletes aiming to reduce fat mass and preserve FFM should consume protein intakes in the range of ∼1.8-2.7 g kg(-1) d(-1).Strong
- A minimum daily protein intake of ≥1.6 g/kg is necessary to observe significant improvements in muscle mass from whey protein supplementation.Strong
- Most athletes ideally need 1.2 to 2.0 grams/kg of body weight/day of protein, preferably split across 3-4 meals.Strong
