Leucine supplementation has shown to significantly increase gain in body weight (p=0.02), lean body mass (p=0.0005) and body mass index (p=0.001) compared with control groups. Furthermore, the benefit of leucine supplementation has a more profound impact on body weight and lean body mass in individuals who have pre-existing sarcopenia.
