Muscle protein synthesis
Supplies whey-type dairy proteins, which are digested quickly and are rich in leucine. Trials showing muscle protein synthesis responses have used concentrated whey supplements rather than ricotta, and the amount of protein in a normal portion of ricotta is far smaller.
Limited evidence. Early human work, or mostly lab and animal research.
