Casein is the overnight protein: it forms a gel in the stomach and releases amino acids over hours rather than minutes, which is exactly what you want across the longest gap between meals in your day.
Quamtrax deliver 28g of it per serving with over 7g of BCAAs, and add something most caseins leave out - medium-chain triglycerides, a fat the body uses quickly for energy rather than storing. Carbohydrate stays under 2g, so it fits a tight diet without argument. The other thing Quamtrax have worked on is texture: casein is notorious for going thick and claggy, and this one is engineered to stay smooth and mix properly.
