I have been taking the methyl B12, as well as Benfotiamine. I had purchased the Vit B6 about the same time; but had read some things that cause concern, so I did not take them.

I had my B12 tested August, 2011, as well as my B6. The range for the B12 was 211 -946. My results were 922. My B6 has a range of 2.0 - 32.8. My results were 54.1. After seeing, I was high in the B6, really made up my mind not to take any Vit. B6.

Appriciate your mentioning Vit B6 may cause neuropathy. Don't know if this has anything to do with my case because I also had spine fusion/laminectomy 5 1/2 years ago. Associated that as the probable cause since things were bad and then the burning did become worse after Bladder surgery and taking the antibiotic Levaquin 500 mg's for 14 days.

Regardless, glad I decided not to take the Vit B6.
