I would assume, since creatinine is the waste product of creatine that is useless in the body.
Creatine works by increasing your body's ability to produce energy. Energy is produced by a reaction in the body that removes one phosphate molecule from ATP to to turn it into ADP. This reaction releases lots of energy, which is how the body performs work. When you ingest creatine, the creatine molecule bonds with a phosphate molecule for form creatine phosphate which then donates the phosphate to an ADP molecule to turn it back into ATP - and then the process repeats.
