Effects of creatine supplementation with and without exercise and diet intervention on body composition, cognitive function, and markers of health in middle-aged and older adults.

This randomized controlled trial, where people are assigned to groups by chance, studied middle-aged and older adults. Researchers compared creatine, a muscle-supporting supplement, with exercise and diet changes. They measured body composition, meaning the amounts of fat and muscle, cognitive function, meaning thinking and memory, and health markers such as blood-test results. The available record does not include the number of participants or the study’s results.

What this means for you: You can ignore this study for now because its results are not provided. It does not currently show whether creatine is worth buying or using.
