I haven’t came across anything of the sort. The only thing I have found is too much B6 can cause nerve sensations, but that goes when you reduce the B6. Other than that, I have read that B Vitamins and high doses of B12 help with nerve damage. In fact, I thought nerve damage can be caused by B12 deficiency?
Yes, B12 deficiency can definitely cause nerve damage. Too much B6 can cause neuropathy.
I saw a very good neurologist and he was adamant about those with nerve issues not taking any B vitamins or multi (because they have B vitamins). Maybe it's with certain conditions . I was more worried about the nerve disorders and trying to avoid another mistake so I didn't press on the B vit issue.
I do know when I had the b12 shot, my nervous system went absolutely crazy. It was the first time I allowed anyone to carry me out of the car even though it was humiliating . I was on fire with pain and very disoriented, every sound was like a loud speaker in my ear and I couldn't tell which direction the sound was coming from .
But I don't know, I'm not sure of anything anymore. Do we take b12 or no? Probiotics or no?
If you don't have serious nerve issues and need b12, then maybe it will help you . If you have anemia msybe discuss it all with a hematologist . If you have MCAS, be careful and look into the different types of b12 shots but people with CFS exclusively , react to all kinds of things too
