Had to pop in on this thread. 3 years ago, before all my symptoms started to ramp up like crazy my b12 number was 362. I was told to take a supplement once a day. Was rechecked twice and told it was "fine". Never did get copies of those blood results. I asked for them but they were not part of the test result package I received. Hummmm.

I was also told that number was borderline low. At the time my folate was extremely low as well
