No, it doesnt cause cancer but elevated levels can put you at a risk of cancer

Dr. Yusuf Suggests...

Take a Anti Ds DNA test Test or Take a APOLIPOPROTEIN EVALUATION PANEL WITH LIPOPROTEIN A Test

Are vitamin B12 injections painful?

Answered by Apollo Doctors

My recent blood test shows that my Vitamin B12 level is 204 pg per ml, while the normal reference range is 211 to 911 pg per ml. Should I be concerned about this mild deficiency? Would you recommend taking Vitamin B12 supplements, or should I try to improve it through natural dietary sources first? Also, what would be an ideal or healthy Vitamin B12 level for someone of my age (27 years) and height (5.11)?

Is there any relationship between vitamin B12 and liver? I have B12 deficiency even though I am non vegetarian (homocysteine is normal). My liver report shows indirect bilirubin 1.19, total bilirubin 1.39, and GGT 67, which are beyond the normal range. Is there any connection between the B12 deficiency and liver report? Last year I had acidity issues and the doctor prescribed Pantocid and Refagut 400 for 30 days. I also have excess vitamin K in my test report. I am non alcoholic.
