Question 241 of 433
Can creatine help me keep muscle even if I am not exercising?
The short answer
Creatine without training has inconsistent evidence for preserving useful muscle function. It should not be presented as a reliable substitute for resistance exercise.
Some small studies report changes in lean mass without an exercise program, while others find little additional benefit. Early lean-mass changes may partly reflect water retained inside muscle cells. More measured lean tissue does not necessarily mean stronger legs, fewer falls, or sustained skeletal-muscle growth.
For someone unable to train normally, rehabilitation, adequate nutrition, and treating the reason for immobility come first. Discuss creatine if appropriate, particularly when training can resume. The strongest practical case remains supplementation alongside resistance exercise in suitable adults.
