How Many Grams of Protein Can Your Body Absorb From a Single Meal During Sleep?
Published June 22, 2026
Most people stop eating protein at dinner and then fast for eight or nine hours, leaving the longest anabolic window of the day completely unfed. The protocol most lifters never run is the pre-sleep casein dose, and the data on it is more precise than the gym-bro mythology around it. In a controlled overnight study, 40 grams of casein consumed 30 minutes before sleep was digested and absorbed normally during the night, raised whole-body protein synthesis rates, and improved net protein balance compared to placebo (see [1]). The body does not "shut down" digestion during sleep. It keeps processing the substrate you give it.
