I have my Vitamin B12 level as 190 pg/ml. My Dermatologist asked me to take Neurobion Injections, 8 injections alternative days and then 4 injections weekly twice, and then 4 injections weekly once. He told me to do this so that my PRP treatments would be effective. Am I really deficient in B12, should I take so many injections or is there anything better I could do. I eat non veg a lot, not sure how it is still deficient. Is it possible that my body is not absorbing the vitamin.
