Carnitine Fatigue Randomized Trial1 Aging is characterized by progressive physiological decline, including loss of skeletal muscle mass and function (Sarcopenia), reduced mitochondrial efficiency, and increased oxidative stress, all of which contribute to frailty and diminished quality of life in older adults ().3Wang Xiaolan (2026)Glycine and N-acetylcysteine supplementation, with or without exercise, in brain health and functional aging: implications for sarcopenia and frailty in older adults
Carnitine Fatigue Randomized Trial1 2 3 4 5 By the age of 70, individuals may experience a 25%−30% reduction in muscle mass, which is strongly associated with impaired mobility, falls, and loss of independence ().3Wang Xiaolan (2026)Glycine and N-acetylcysteine supplementation, with or without exercise, in brain health and functional aging: implications for sarcopenia and frailty in older adults
Carnitine Fatigue Randomized TrialLow circulating glycine levels have been associated with insulin resistance, obesity, and higher cardiometabolic risk (,).3Wang Xiaolan (2026)Glycine and N-acetylcysteine supplementation, with or without exercise, in brain health and functional aging: implications for sarcopenia and frailty in older adults
