I am not a doctor Drevy , but Zandopa is mucuna base and my other friend here that is going natural for PD takes the Rhodiola and mucuna capsules also.. she also makes and takes fermented Payaya and fava tincture. She does not seem to be having a problem with it. She just made a visit to her neuro at Vanderbuilt (spelling?) and they said she checked out good..just keep doing what she is doing and keep notes so she can teach them about the natural things we are doing. A definite Thumbs UP.
I have just reduced down to 1/2 Swanson brand 400mg Rhodiola before breakfast and seem to be doing ok with it this time. Tried it before and my energy level dropped so I had gone back on a whole again. Been taking 1/2 for a week and still ok this time. (I still haven't had time to make the Rhodiola extract ..taking apart all the capsules takes a while....but I will get to it soon.
