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.

Physical Activity Performed in the Evening Increases the Overnight Muscle Protein Synthetic Response to Presleep Protein Ingestion in Older Men.

Randomized Controlled Trial

2016 Jul

The study shows that when older men drink a protein shake before bed, about 54% of the protein shows up in their blood overnight, which means it’s being digested and absorbed well—just as the claim says.

If older guys drink a protein shake with 40 grams of protein right before bed, about half of that protein shows up in their blood overnight — meaning their bodies are still digesting and using it while they sleep.

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.

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.

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 you eat a scoop or two of casein protein before bed, it probably won’t change how hungry or full you feel the next day — at least for healthy young or active older people.
