What happens when you eat protein before bed after working out?
Presleep dietary protein-derived amino acids are incorporated in myofibrillar protein during postexercise overnight recovery.

Young men who lifted weights ate protein with or without extra leucine before bed, or nothing. Scientists checked how their muscles used the protein 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.

If young, healthy guys eat 30 grams of casein protein — with or without an extra 2 grams of leucine — before bed after working out, it doesn’t actually help their muscles grow more overnight.
If young, healthy guys drink a protein shake with 30 grams of casein before bed after working out, their muscles may recover better overnight because their bodies are building more protein while they sleep.
If young guys lift weights and then drink a protein shake with 30 grams of casein before bed, that protein actually gets used to repair and build their muscles while they sleep.
