Hi,
I can't be much help to you, Kathleen, sorry, as I'm actually finding I'm less tolerant to what I was tolerating, with care, pre-HRT!!!! So, that's proving to be another issue! However, yeah, B12 is pretty standard for supplementing if vegan and it's important to check for absorption, a bit like the "free" levels to assess what is actually available to use? It's possible to have "normal" or even high levels which are not "free". A test for intrinsic factor will assess your capacity to absorb. However, the theory one can have "too much" is a bit of a myth as any excess is just passed in urine. I now tolerate what little alcohol, dairy and sugars I had before almost not at all which is really interesting, but the diet I try to follow, 5:2/6:1, is a low GI (glycemic index) for slow release, therefore gentler on the systems. Hope there's something here to help. Keep us posted!
