I have almost all characteristic of under methylator. I have made some blood test and my homocysteine is 5,71 umol/l , b12 is high and folic acid is 12,3 ng/ml. I am also high histamine guy, also with bad cholesterol 200 LDL even with a good keto diet. I am getting into methylation but in Poland we dont have much information about that. I am reading a lot of english articles about it. And on many pages it says that under methylators should avoid b12. I wanted to improve my methylation with mb12 1000mcg, metafolin 800, TMG and SAMe... maybe some b6 p5p also. But now i dont know what to do since in protocols in this forum it always says that the basic is b12. But under methylators should avoid it. So what can i do?
