I have had excellent results within a few days after I started taking Immunocal. My energy level is 3 times what it was and the Parkinson’s medication is lasting longer between doses. I have even cut back slightly on the meds. I was having a balance problem and now I am not. I still have the “internal jittery” feeling late afternoon into the evening. I am taking a packet of Immunocal first thing in the morning with about 6 ounces of juice.
