Hi I am new here, want to talk about nutritional supplements and parkinsons

Hi I am new here,my father has parkinsons and I am happily surprised that after my father stopped taking sinamet which was making his head bob, he tried a supplement called Immunocal and his hand stopped shaking after a week and he said his head is much clearer. this is the web where you can read about it http://hghplus.info/parkinson/
does anyone else have similar experiences? I want to know what we can expect in the future.
