I take Jarrow B12 but not the formula you mention here.

I also take 100mg of RLipoic Acid now. I tried it a year ago and could not take it, caused severe heartburn, but now I take it with a half teaspoon of baking soda and so far no problem, been over a month.

Burning is severe for me and some things have helped but nothing cures it. Benfotiamine use to make it go away then quit. RLipoic acid has done nothing so far for me so far as I can tell...not even sure I should keep taking it.

Zyflamend has helped a lot but as with befotiamine the longer I am on it seems it is not working as well but it does still help.

It's like my body adapts to anything that works at first then it wears off.
