If young, healthy guys drink a whey protein shake before bed after a long workout, their muscles build more overnight — both the tiny energy factories and the actual muscle fibers get a boost.

Similar Assertions

If young, healthy guys eat 45 grams of protein before bed after a long run, their muscles repair and rebuild better overnight — whether they choose whey or casein protein doesn’t matter.

93%

Drinking 45g of either whey or casein protein before bed helps muscle recovery just as much after endurance exercise in young, healthy guys — neither one works better than the other.

If young, healthy guys drink a protein shake before bed after working out, it doesn’t matter if it’s whey or casein—both help their muscles recover just the same overnight.

92%

If young, healthy guys eat 45 grams of protein before bed after a workout, their muscles build more repair and energy-related proteins overnight compared to not eating protein.

If young, healthy guys drink a casein protein shake before bed after a long workout, their muscles build more overnight — both in the energy parts of cells and the actual muscle fibers.
