I've done all that as my levels were low after I contracted CoVid May 1, 2022. Finally got into the Long Haul Clinic at OHSU on March 27, 2023. Yes, after the doctor's referral, it took 9 months to be seen. They ran bloodwork again, and all my levels were in the upper range of where they were supposed to be, except Vitamin B12 which was significantly above the range. I felt no better, and I was surprised they were all where they were supposed to be. Also took Turmeric and drank lots of ginger tea for inflammation and gastrointestinal issues. Neither of those worked either. I have just plateaued. I'm better than the first 3 months of the infection, but so far from who I used to be.
