That’s a great question/point. Excessive amounts of B6 can cause symptoms of neuropathy, yet it’s in a bunch of supplements.

It happened to me because I have POTS, which requires additional electrolytes. My electrolyte supplement had a ridiculous amount of B6, unknown to me. I thought I was having a flare up of my neuropathy and thankfully my dietician figured it out and after a trial of changing out the electrolyte supplement, I went back to my baseline and my B6 numbers went down.
