For heartburn issues, make sure you take your supplements (except the B12) with some food, and plenty of water, so they can dissolve properly.

My son gets heartburn from B-complex. Always.
There is an enteric coated P-5-P which may help. It has B2, B6, and a small amount of magnesium in it. If you are taking B-complex, try, the NOW enteric coated. (it does not dissolve until past the stomach completely).

Since you take the Benfotiamine already, you don't need the complex if you switch to the NOW product.
