What is uncertain
Read off the same rows as above. Nothing here is added that the entry does not itself record.
- Studies disagree: Overnight muscle synthesis (mixed agreement).
The evidence in words
What it is
Casein is the slow-digesting fraction of milk protein that forms a gel in the stomach, releasing amino acids over hours.
How it works
Its slow digestion provides a prolonged amino-acid trickle, of theoretical benefit overnight or between meals.
What the evidence shows
Pre-sleep casein modestly supports overnight muscle protein synthesis and recovery in some trials; over a full day, matched total protein makes casein-vs-whey differences small. A reasonable pre-bed or meal-replacement protein.
Safety & interactions
Very safe; contains lactose.
Bottom line
A fine slow protein, best pre-sleep or as a meal replacement. The whey-vs-casein debate matters far less than hitting daily protein.
