@Fraser ... I have Vit B12 injections every 3 months due to low levels, but as I don't take supplements or weight loss stuff, I should be OK & safe from doubling up (and it is a different one to B6.)
It seems that there are a lot of supplements that have Vit B6 in them (the problem one, if taken to excess) but it is not always obvious in the labeling (sometimes only seen in the small print.)
Those taking numerous supplements (any of them) with Vit B6 are the ones to keep an eye on, as cumulatively, the combined dosage may cause an accidental overdose ... which may even 'appear to be' neuropathy symptoms, with people taking even more again, as it is seen to be a possibly solution to 'reduce' the symptoms!
Personally, I'd be getting a blood test if you've been on Vit B6 for a long time ... particularly if you're taking other supplements as well. Take care
