Strong Support

Taking 40 grams of casein protein before bed doesn’t really help older guys build more connective tissue in their muscles overnight — especially if they didn’t work out first.

Similar Assertions

For older guys who work out and eat a protein shake before bed, their bodies build more connective tissue in muscles overnight than if they just had the shake or did nothing.

If young guys work out and then drink a protein shake before bed, it doesn’t help their muscles’ connective tissue build more overnight — not any more than just working out alone.

If healthy guys drink a protein shake with 20-40 grams of casein right before bed, their bodies keep building muscle overnight — even if they worked out earlier in the day.

If older guys around 72 drink a protein shake with 40 grams of casein before bed, it helps their muscles repair and grow overnight better than not having it.
