topicCasein Protein Sleep Quality 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 (,).
