I just don't know!!

I have absolutely no idea what type of B vit complex I should be taking. I am MTHFR and my former FMD said I shouldn't be taking methyl and with B12, I should be taking the hydroxycobalmin. Then when I changed FMD's, they recommended me on which I have been taking although only half content as I felt I had a bad reaction to the Thornes Basic B causing my existing anxiety to worsen.

What the hell am I supposed to be taking, so confused right now. If the Metabolics one is the right one then I will feel better in increasing to a full cap because my B levels arn't brilliant, although my B12 is OK.

Can someone help please?

You might get some replies if you defineMTHFR, I m afraid I don't know what it means

Good luck


Hi Susie. This is a genetic defect that is really common to some degree, some have it worse than others. It makes it difficult to metabolize some substances. If you have a difficult time raising B12 and folate levels it could be due to that.


Info on MTHFR mutation:


Maybe there is something in this link that might help. There is another B12 I've been reading about adenosylcobalam. You can read about it at Amazon. Was there a high amount of folate in your B complex? I take Thorne Stress-B complex.


I recommend Jarrow Formulas, B-Right:

It contains highly absorbable folate and B12:

"Methyl folate ((6S)-5-methyltetrahydrofolic acid or (6S)-5-MTHF) is the most biologically active form of folic acid (folate). Quatrefolic is the 4th generation development in folate delivery."

"Methylcobalamin is better absorbed, retained and utilized than other forms of B12. Methylcobalamin and niacinamide support brain and nerve tissue."
