    Whey protein appears to resist coagulation in the stomach and pass quickly to the intestines (at least when compared to casein and other proteins). Leucine spikes in the blood approximately 40–60 minutes after the ingestion of whey protein,[1] which is quicker than that observed for other protein sources (e.g., tuna, turkey, and egg).[2] As such, whey rapidly stimulates muscle protein synthesis (MPS).
