Mercury and Formadehyde in B-12 Injections
I have received B-12 injections (cyanocobalamin) monthly for 20 years due to pernicious anemia. I recently saw a nutritionist who, through testing, found I have mercury and formaldehyde toxicity in my body. I'm wondering if this may be a result of the B-12 injections. Is there mercury or formaldehyde in these injections? How can I determine this? I've been unable to find my answer in online research.
