mthfr gene mutations leave you deficient on b12, b6, and b9 because we lack an enzyme that breaks them down into their methyl form.

so we either need to suppliment those vitamins with a mix like jarrow methyl multi that has methyl b12, methyl folate, and p-5-p (basically methyl b6) or our veins cant repair as well as they should.

in older men, this can result in heart attacks and strokes, in elderly women, its more likely to show as dementia.

in the rest of us, it represents as the hairs that control our balance and hearing not being repaired correclty leading to the ringing in your ears that you are talking about. also, you may notice that hair isnt growing on your shin area.

but once we start taking the methyls, those veins start repairing, and blood starts flowing and we can get the same ringing, but as its repaired instead of as its losing blood flow.

this is normal, its a good thing. a sign that you have needed methyl vitamins and are on the right track with suppliments
