Effects of leucine-rich protein supplements in older adults with sarcopenia: A systematic review and meta-analysis of randomized controlled trials

Lee SY, Lee HJ, Lim JY. Effects of leucine-rich protein supplements in older adults with sarcopenia: A systematic review and meta-analysis of randomized controlled trials. Arch Gerontol Geriatr. 2022 Sep-Oct;102:104758.

Data from six randomised controlled trials including a total of 699 participants, demonstrate that the consumption of leucine-rich protein supplements (offering 3-6g leucine per day) can improve muscle strength, muscle mass and performance in sarcopenic older adults compared to a control group (P<0.001) and may be suggested as a nutritional treatment for sarcopenia.
