B12 def. Makes me sick!

[Callumsmom]

I have a b12 deficiency but taking the b12 shots or oral tabs makes me very sick and extremely tired. What could cause this?

Hi You could try taken Brewers Yeast tablets, as another way of getting your B 12, as these may sit with you better, and then you do get the full range of your Bs.
Good Luck

You may be having a reaction to the additives, fillers, sugars, artificial colouring, or flavourings. This may be a bit of trial and error to find one that suits you.  I personally had allergic reactions with B12 injections - could barely breath for three days and a 4 month acne rash on my face, chest and belly.  I now use sublingual (under the tongue) B12 spray from bioceuticals (Australian Brand) and i have used this product for 3 years with no problems.
