Study summary
There are times in life when people cannot use their muscles, such as during illness or injury. Muscle and mitochondria (the 'energy factory' in cells) health decline very quickly when people cannot use their muscles, but certain foods can help reduce these declines. Recent research suggests that Urolithin A, which is a natural compound that can be produced after eating pomegranates, nuts, and berries, improves muscle health. In this study, the investigators aim to investigate if a protein beverage (standard care during disuse) with or without Urolithin A can reduce or prevent the loss of muscle health while wearing a knee brace (muscle disuse).
