Drinking alcohol with a sports drink after a workout hurts muscle recovery more than drinking it with a protein shake—protein helps a little, but it’s still bad.

Alcohol Ingestion Impairs Maximal Post-Exercise Rates of Myofibrillar Protein Synthesis following a Single Bout of Concurrent Training
After working out, drinking alcohol lowers muscle repair, but if you drink alcohol with protein, your muscles repair a bit better than if you drink alcohol with sugar — so protein helps, but doesn’t fully fix the problem.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
The relative protective effect of protein vs. carbohydrate against alcohol-induced MPS suppression under controlled conditions.
A double-blind RCT with 40+ males, comparing 1.5 g/kg alcohol + 25 g whey protein vs. 1.5 g/kg alcohol + 25 g maltodextrin vs. 1.5 g/kg alcohol + 50 g whey protein after concurrent exercise, measuring MPS over 8 h to determine if higher protein dose further mitigates suppression.
Whether athletes who consume alcohol with protein-rich meals have better long-term muscle retention than those who consume it with carbohydrate-heavy meals.
A 12-month cohort study of 150+ athletes tracking post-training alcohol intake, macronutrient composition of accompanying meals, and changes in lean mass via DXA, controlling for total energy and training load.
Whether amino acid availability modulates alcohol’s suppression of translation initiation.
Mice given alcohol (1.5 g/kg) after exercise and randomized to receive isocaloric carbohydrate, protein, or amino acid solution, measuring muscle eIF4F complex formation and ribosome loading.
