Could i still have a B12 deficiency?


I have suffered for a few years with a sore tongue and mouth, severe tiredness, forgetfulness, depression, weakness, headaches and more recently migraines and blurred vision.

When i had my third child 2 yrs ago, they tested my b12 and it was low so i had a course of injections. Ever since then , the symptoms haven't gone away but blood tests always show up no signs of a deficiency, although once it did show low folate levels and i took a supplement for a while.

I was a vegetarian from the age of 14 to 23 and didn't supplement my diet at all. Now,i have weakness in my limbs, i find it hard to wake up in the morning, i find it hard to grip things, my memory is not good and i have palpitations all the time. When i had bad migraines recently my gp put me on amitryptilline which was good but made me feel even more tired, before that all my symptoms have been put down to depression.

I am now on nothing, no antidepressants, and i feel the worse ive ever felt, do you think i have a B12 deficiency but it is not showing in the tests and what should i do?

Thank you,

Multiple deficiencies and gluten sensitivity
by: Kerri Knox, RN- The Immune Queen!

Hi Laura,

Please read my page on Vitamin B12 Levels and Vitamin B12 Deficiency Treatment. I don't look at levels at all because they mean nothing.

But I think that you are being unrealistic to think that vitamin B12 is your ONLY problem. If you are b12 deficient and you are not a vegetarian anymore, then why are you B12 deficient?? You are probably not ABSORBING B12 because of Increased Intestinal Permeability most likely due to Gluten Sensitivity.

Because this is the case, you probably have multiple nutrient deficiencies contributing to your problem- as well as the direct effects of feeling bad from gluten sensitivity.

I suspect that you also have at the VERY least:

Signs of Magnesium Deficiency


Symptoms of Vitamin D Deficiency

While taking some vitamins might help you to feel better somewhat, you're likely going to need to revamp your entire diet if you want to resolve this problem and actually feel like a normal human being again.

I suggest that you start by taking a look at The Healthy Urban Kitchen and following their program carefully.

Along with vitamin d testing and some serious nutrient supplementation that includes a HIGH QUALITY multivitamin along with targeted nutrients and a strict gluten free diet, you just might start to feel better.
