Slightly tangential to Vitamin B12 monitoring but Dr.NutriCornell reminded me — has the insurance landscape changed recently?

I know it is not exactly on-topic but it seems related enough to ask here rather than starting a new thread. Apologies if this has been covered — I did search first.

Follow-up question: what labs did your doctor order to monitor this

This is exactly right. rick_sfbay articulated what I have been trying to explain to my friends for months. The Vitamin B12 monitoring aspect is what made the difference for me.
