Pre-Sleep Casein Supplementation, Metabolism, and Appetite: A Systematic Review
Dela Cruz J, Kahan D
Published in Nutrients
Methodology
PRISMA systematic review of trials of pre-sleep casein on energy expenditure, lipolysis, appetite and food intake in healthy and overweight adults
Key Findings
Pre-sleep casein has been linked to improved muscle protein synthesis, mass and strength adaptations, but effects on overnight metabolism, lipolysis and appetite are inconsistent.
Conclusions
Pre-sleep casein appears metabolically safe but its non-muscular effects on metabolism and appetite remain unclear.
Limitations
Narrative synthesis without pooled estimates; small heterogeneous trials, mostly in young men.
Supplements Studied
Pre-sleep casein supplementation has been attributed to improved adaptive response by skeletal muscle to resistance training through increases in muscle protein synthesis, muscle mass, and strength.
Outcomes Measured
Pre-sleep casein supplementation has been attributed to improved adaptive response by skeletal muscle to resistance training through increases in muscle protein synthesis, muscle mass, and strength.
