Population aging has become a significant global concern, and Taiwan is set to officially enter the "super-aged society" in 2025. As individuals age, various physiological functions gradually decline, including a reduction in muscle mass, which is a key aspect of the aging process. This interventional study aims to investigate the effects of leucine-rich protein combined with polyunsaturated fatty acid supplementation on middle-aged and elderly individuals (aged 50 and above) who are at high risk for sarcopenia.
