Could creatine be beneficial for those of us with Parkinson’s disease? I am a 60-year-old woman, diagnosed in 2022, and my medication is working quite well for me (pramipexole, Xadago, Madopar, Dinetrel and Dulexotin), but my muscles in particular are often stiff and tired, so I’m wondering if it might be worth giving it a go? Could it be harmful in any way?

There have been a few studies on creatine (a substance found in meat and fish and available as a dietary supplement) as a treatment for Parkinson’s. It does not appear to have any effect on the disease, but the results are somewhat contradictory, so we do not know for certain, although a large placebo-controlled American study concluded in 2015 that creatine has no effect on Parkinson’s. According to the studies, it seems fairly harmless to give it a go, but it’s probably a waste of money. /Dag Nyholm
