Supplements have not been found to be helpful in treating PARKINSON S DISEASE directly, however, if you want one suggestion which has been recently shown to do better than almost anything else available it would be to talk to your doctor about getting a referral to a neurologist familiar with the latest technology having to do with the infusion pump in the GI tract that releases carbidopa/levodopa CONTINUOUSLY. This is most likely the best way to supply dopamine precursors to the body as opposed to what we traditionally been doing in terms of dosing tablets every so many hours. In your case, every 2.5 hrs. is not bad at all as a dosing interval......but dosing the medication into the gut for CONTINUOUS ABSORPTION is now recognized as the most likely delivery system to give patients the best possible long term outcome of relief and AVOID common side effects of dyskinesias and other problems often seen in conventional dosing interval methods.
