Hello, hoping someone who has some knowledge on this can reassure me . I've had my b12 results and it's sky high 4000 ng/L (injections every 6 weeks). Last year it was 2300 without injections for 6 months. My folate is borderline line low. My doctor has told me to stop having them? Couple years ago my b12 was 173ng/L but still in range. The injections make me feel better and I can tell when I'm due them. Not sure what to do?.
