Yes, eating protein before bed helps your muscles build more protein overnight, especially if you exercised earlier. Older people might need more protein than younger ones to get the same benefit.
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 you're eating more protein overall, it might be that—not your bedtime snack—that's helping your muscles grow. So taking protein before bed might not be the real reason for better results.
If young guys who work out lift weights regularly, having a snack with about 30 grams of protein before bed might help them build more muscle and get stronger — especially if they don’t already eat a lot of protein during the day.
Eating protein before bed won’t mess with your hunger or slow down your metabolism the next morning — so it’s safe to add to your daily routine if you're a healthy or overweight young guy.
If older adults eat protein before bed and also do strength training or use muscle-stimulating devices earlier, their muscles may repair and grow more overnight.
Eating 20 to 40 grams of protein before bed helps your muscles repair and grow overnight, especially if you worked out in the evening.
