I want to increase my protein intake but have read (and seem to experience) a decrease in carbidopa/levodopa effectiveness if I eat high protein foods. Do plant based protein sources work better when combined with Parkinson’s medications?



I am not aware of any research that addresses this question though it is certainly an interesting one. My simple minded understanding is that protein is protein whether it originates from animals or plants. My intuitive guess is that the cellular structure differs significantly depending on the source.

Under your doctor’s close supervision perhaps you might conduct a little experiment using a sample of one (yourself) to eat only plant based protein for a short period to see if it makes a difference or not.

Does anyone out there taking Carbidopa/levodopa have any personal experience with eating plant based protein? Please let us all know by commenting below. I know Pat would appreciate hearing about your experience.
