Amino acid ingestion improves muscle protein synthesis in the young and elderly
Can both young and old benefit from EAAs? Yes!
In this study, researchers concluded that "although the influence of insulin and the time course of muscle protein anabolism after the bolus ingestion of EAA differs in young and elderly, EAA ingestion is nonetheless effective at acutely stimulating muscle protein synthesis in both age groups."
