Yup, I'm homozygous c67tt.. and also now low b12, b6, folate, zinc.. ugh and more! I guess I never realized that it was a conversion issue.. I sometimes wonder if that is my main malfunction!? Though I know I Have autoimmune issues as well, with my always high ANA and good response to IVIG..
So were you taking the cyano shots or methyl? Yes.. I pay $20 for a bottle of b12 that lasts me about 3 weeks.. so not awful.. but still, it's nice when it's free, especially with all the other fun costs! DO you notice a difference with the methyl sublinguals? I have had proprioception issues with my feet, especially left foot.. since starting the B12, it's so much better.. My toes don't do the strange up going walk thing anymore I always get the proprioception tests wrong! I guess I am still looking and hoping for that magic fix!
