The problems I feel are noteworthy are: 1) There is no kind of standardization or safety control in the production of melatonin. Each company may manufacture it according to its own policies and standards of safety, cleanliness, etc. 2) Parkinson's is a complex disease, with many unknown factors. Adding an additional unknown, in the form of a hormone, may be unwise, particularly in light of your father's operation.
