Older men drank protein before bed and either exercised in the evening or didn’t. Scientists checked how much muscle they built overnight.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

For older guys, working out in the evening and then having protein before bed helps their muscles use that protein better overnight than just having protein alone.
When older guys drink a protein shake with 40 grams of casein right before bed, about half of that protein shows up in their blood overnight — meaning their bodies are good at digesting and using it while they sleep.
If older guys do some exercise in the evening and then eat 40 grams of protein before bed, their muscles rebuild better overnight than if they just ate the protein alone.
If older guys work out in the evening and then eat protein before bed, their muscles use that protein better overnight to repair and grow.
