Pre-Sleep Protein Ingestion to Improve the Skeletal Muscle Adaptive Response to Exercise Training
Nutrients (2016) · Review
Protein ingested prior to sleep is effectively digested and absorbed, and thereby stimulates muscle protein synthesis rates during overnight recovery.
Based on meta-analysis showing significant HAM-A score reduction (p=0.0007) and RCT evidence at 125mg dose. High heterogeneity (I2=98%) in pooled analysis suggests variable response. Extract standardization affects bioavailability.
Based on systematic review (n=387) showing pre-sleep casein enhances training adaptations and increases muscle fiber size. Optimal dose identified as 30-40g. Limited to pre-sleep timing and requires concurrent exercise training.
