This is news to me:
"Both type 1 and type 2 diabetics may also be advised to supplement thiamine based on high prevalence of low plasma thiamine concentration and increased thiamine clearance associated with diabetes. " from https://en.wikipedia.org/wiki/B_vitamins#cite_note-30
My previous doctors, endo’s never mentioned Vitamin B’s,
Furthermore, wikipedia stated:
Vitamin B1 (thiamine) A coenzyme in the catabolism of sugars and amino acids.
(Is there a category for both Type 1 and Type 2? as this information seems to apply to both type 1 and type 2)
