Hi, I posted a few days ago due to feeling grotty and wondering whether I was over medicating ( results in those posts) what I would really like to know if anybody has any ideas is whether I will ever be able to convert properly due to my low b12. As mentioned in my last posts I am unable to take either vitamin b12 injections or supplements or even fortified foods so have to rely on absorbing a small amount through my diet and have a really low b12 250 at the very highest and most of that is left over from the last injection I had, it was 85 before then. (140-250 insufficient). Could this mean that due to my deficiency that I will be unlikely to do well on levothyroxine alone? I would be really grateful for any thoughts on this please.
