topicCasein Protein Muscle Synthesis Randomized Trial
claimOne of the most conspicuous manifestations of aging is the insidious reduction of skeletal muscle mass and strength, a phenomenon referred to as sarcopenia, which is intricately associated with frailty, an elevated risk of falls, and metabolic dysregulation (,).

topicCasein Protein Muscle Synthesis Randomized Trial
claimSimultaneously, age-associated deficits in glucose metabolism, heightened low-grade inflammation, and cognitive decline further complicate health outcomes within this demographic (,).

topicCasein Protein Muscle Synthesis Randomized Trial
claimHistorically, proteins derived from animals, such as those found in dairy, have been regarded as superior to their plant-based counterparts due to their elevated EAA content and more advantageous digestibility profiles (,).

topicCasein Protein Muscle Synthesis Randomized Trial
claimBACKGROUND/OBJECTIVE: Prolonged bed rest is highly prevalent among hospitalized older adults and markedly accelerates the loss of muscle mass and physical function.
