We may be related!! I have not had that particular test but my son has and he (and I am almost positive me too) have the MTHFR gene mutation which makes our bodies absorb some B vitamins like B6 instead of urinating them out like most water soluble vitamins. I am okay taking B12 and it doesn't bother me but I absolutely cannot take B6 in any supplement. I thought for sure that I had Parkinson's or MS and my neurologist did as well before she found that my B6 was too high. If you know that you have that or a similar gene mutation, I would stay away from all B vitamins until you get a blood test to check your levels. Have a blessed day!
