The Claim

Alcohol consumption following concurrent exercise reduces mTOR phosphorylation at Ser2448 by approximately 50% relative to protein ingestion alone, indicating a suppression of the mTOR signaling pathway critical for muscle protein synthesis.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

If you drink alcohol after working out, it can cut in half the body’s signal to build muscle—compared to just drinking a protein shake after exercise.

See the scientific wording

Alcohol ingestion after concurrent exercise suppresses mTOR phosphorylation at Ser2448 by approximately 50% compared to protein ingestion alone, indicating impaired activation of a key signaling pathway for muscle protein synthesis.

What the research says

  1. Study: Alcohol Ingestion Impairs Maximal Post-Exercise Rates of Myofibrillar Protein Synthesis following a Single Bout of Concurrent Training

    The study found that drinking alcohol after a tough workout reduces a key muscle-building signal in the body compared to just drinking protein, which supports the claim that alcohol hampers muscle recovery.
