Maybe there is something to it......something suddenly gave me neuropathy out of the blue. I was taking subliminal Vitamin B12, a B-100 complex, slow Niacin, B-2, and another supplement with B6 in it as suggested by my cardiologist. Didn't really have other symptoms til this, tho. I have been off the B-100 and B-12, and B-6 for 2 months now, but NO relief. Tried Red light treatment, did nothing.....tried Tens unit.....did nothing.
I noticed how much B6 of the pyridoxine form you were taking and I have no doubt that caused your neuropathy.
There are many reports of B6 toxicity. Search reddit, Facebook, and elsewhere. Some get it from relatively lose doses of pyridoxine. Can get it also from P5P, but not as easily. At one point I was overdosing a methylated, active B Complex because I liked the feeling I was getting from it, and after a while of that, which worked out to perhaps 150 mg/day of P5P, I experienced some strong neuropathy in one of my arms. Discontinued it immediately since I know B6 can cause neuropathy, and it went away after a few days.
Also depends on how much water you drink. Drinking more water makes overdoses of B6 less toxic. However, toxicity from pyridoxine definitely will be more persistent than toxicity from P5P. At least that's my understanding based on some reading.
Have you had your B6 levels tested?
Also, my suspicion is that taking the recognized, celebrated B vitamins must in general ultimately do some harm since all the non-celebrated other compounds that are important too are not being supplemented at all while these celebrated compounds are supplemented in mega doses. However, B6 certainly is the most toxic and problematic of them all.
I have been off the B-100 and B-12, and B-6 for 2 months now, but NO relief.
In this case it sounds like permanent damage was done. However, one thing you should first try, besides excessive water intake to flush out your body, is supplementing with some P5P.
See for example:
"Unfortunately,
large amounts of pyridoxine can compete with the active P5P form at the B6 receptors. This means the inactive form can actually get into the B6 receptors by mistake. And because it’s inactive, it won’t work. This can result in an overall reduction of B6 activity."
The Thorne B Complex has a low dose of P5P at 10 mg per capsule. Still a mega dose compared to what is available in food.
Current era science likes to grossly oversimplify the chemical composition of food. Fact is there's an amazing array of compounds besides what is commonly talked about, celebrated, and supplemented.
Also, in the thread I linked in the original post, the OP there cites two links before concluding:
Brain damage and cognitive deficits greatly precede neuropathy, even at more reasonable doses.
Have you noticed any cognitive deficits?
