I hesitate to even start a thread that is heresy to many, many PD sufferers, many self proclaimed pharmacologists/biochemists on this forum and many of their physicians as well. It is all about a couple of PD drugs that can go very deadly if used inappropriately.
Please realize, if you can do so, that Carbidopa and/or Benserazide irreversibly bind to and permanently deactivate PLP, the active form of vitamin B6. Unfortunately for the uniformed, PLP is pretty important for your overall health since it is required for the function of at least 300 or more enzymes and proteins. Yes, quite a few. In other words, for those who aren’t self proclaimed pharmacologists/biochemists, PLP impacts almost every major system in the body in one way or another.
In plain English, try to use extreme caution in maxing out (as in 4-5-6 times a day using maximum doses) on either Carbidopa or Benserazide because you are inevitably going to create a host of peripheral health problems that will prove catastrophic in the end. It will all become a tangled web of ill health that has no apparent cause because you supposedly are doing the correct thing.
I apologize for calling into question PD dogma that always says: MORE Sinemet or Madopar is always better. It simply isn’t. The mortality statistics are troubling.
