Last month I went to a Doctor off the grid (not on my insurance) to do a more accurate test through Spectracell at a cellular level for vitamins & minerals. I knew my regular doctors wouldn't order it. I got the results today.

Test results showed a B1 (Thiamine) deficiency. According to the lab I should have greater than 78% and mine was 72%. I have a vitamin C deficiency as well and am borderline deficient in Manganese which helps the body absorb B1.

I do know that a Thiamine deficiency is listed as a cause for neuropathy but I do not know if it is the cause of mine. I must say this as much for me as you.

Thanks to a post I had read by MrsD, after my blood test I had begun supplementing with Benfotiamine, a more bioavailable and physiologically active form than Thiamine. When my doctor looked up some information she came back in the room and told me I should immediately start taking Benfotiamine. I was able to tell her I had begun 8 days ago! I can not even begin to tell you how great it made me feel to know something she had to look up! I just had to share.
