Hi there. I just wondered if anyone knows the guidelines for treating b12 deficiency back in 2006? I was very ill for years and when they tested my b12 it was 115. I wasn't prescribed any tablets or injections. Just told to eat more green veg. I did this and bought a b complex of my own accord. A year later my b12 was at the lowest end of the range but I told by my doctor at the time that this was fine even though I was still very symptomatic. I fear raising folate with green veg may have skewed the results. Does anyone know where I stand legally with this? I have suffered for years.
