Interactions

Possible interactions include:

Caffeine. Taking caffeine and creatine together might reduce how well creatine works, but more research is needed. In one large study of people with Parkinson's disease who took creatine, those who consumed more than 300 mg of caffeine a day had faster progression of Parkinson's disease. More research is needed.
