Some time ago, I came across information about the latent toxicity of B6 in connection with neuropathy. I don't remember where it was, but it was a serious study from medical reports. I am sending a link to a similar one, which is worth reading. There is no smoke without fire.

Besides, multivitamins are convenient, but often one comes at the expense of another's effectiveness. I prefer separate ones and the own body's control over each.

Thank you Peter. Armchair dr here. Scratching in places my real Drs might have not.
I have added the, new to me, study you included.
Supposively, I eat a very nutritious diet. Considered not so by some. This I know, my choice to eliminate almost all carbs in my life— has made a difference in the neuropathy.
Wishing you the best

I have found exactly one multivitamin without B6, and would love to learn of others. It's Desert Harvest: https://desertharvest.com/products/multi-vitamin-low-acid-90-capsules. (Although you can find it on Amazon, it comes with a high delivery cost.) I've been taking it for a while, and will see what my next round of blood test shows. I have not found an objective, independent review of the product, nor any evidence one way or another that what's in the bottle is what's on the label, which is, of course, true of almost all supplements. Not a fan of anything that combines calcium and iron, since doing this lessens their absorption, but since I take those supplements independently, it doesn't matter to me. Be aware that whatever capsule material they use occasionally tears in the bottle -- usually only one or two capsules, but it does mean that it's worth looking closely for the torn capsules to discard them.

Although B6 is important, I prefer separate supplements to multivitamins, mainly because there are no high-quality complexes available.
Even iHerb.com, which has perhaps the widest range, does not offer any such products. Amazon is not a reference for me, as my experience with it has been below average. This is my personal opinion.

I am confused about Vitamin B. My doctor told me to take a B complex and that would help with neuropathy. It seems there are different opinions on this.?

I take B6T smart, a B-complex. T stands for toxicity. It has 50% DV of B’s minus B6. They also have the multi vitamin that I believe has 25% DV. I found it through FB group called Understanding B6 Toxicity using Western Research. Hope this helps.

For Vitamin K2, I buy Nordic Naturals, with K2 as menaquinone-7, MK-7. It does not have B6 in it, but it comes with D3 1000 IU, which I would rather take separately (my endocrinologist actually prescribes it for me). They only have it as a gummy with 2 g of sugar, another element I would rather not have, but it's a brand that can apparently be trusted, according to my PA-C, who has a Ph.D. in herbal medicine and conducts 3rd party reviews at the university medical center where she practices.

As for multivits, I take Nature Made Postnatal vitamins, mainly because it doesn't contain over-the-top amounts of each vitamin - most are at 100% of the RDA. It does have 2 mg of B6, but I only take the multivit twice a week. Because I've been dangerously low in Vitamin D and Vitamin B-12 in the past, I feel like I should probably top up most of the needed vitamins a couple of times each week, just in case there are others that I'm not getting enough of.

I use B12 injections and it seems to help.

They sell a multivitamin without B6 at https://understandingb6toxicity.com/

B6 is a needed Supplement...but too much can cause the problem your trying to address..
So testing is a wise solution to see where your at on your "B's"
