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 limited RCT data showing no group-specific effects in n=28 study. One small study (n=10) showed some promise but very limited sample size. Bioavailability concerns limit effectiveness estimates.
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.
AI-estimated from published studies. Interpret as directional guidance.
Casein Protein has a higher evidence score (7.5/10 vs 4/10) and wins in 2 of 3 categories.
For build strength & muscle, Casein Protein has a higher relevance score (88 vs 70).
No known interactions between Beta-Ecdysterone and Casein Protein have been documented in our database. However, always consult a healthcare provider before combining supplements.
