Hey folks I'm new here. Years ago I was diagnosed with IBS and suffering with bouts of fatigue for a long time. I've had sooo many tests done and my Doc suddenly has informed me that my blood tests have showed a little lower than normal B12. He said not enough to be concerned but I have a feeling what I've been struggling through is more than a small concern. I have many questions but first I'd like to know,

What is really concidered low level? I believe that I've suffered many of the symptoms that I see other B12 dificient people in this forum for years.

I started b12 about 2 weeks ago, 1000 mcg, and felt terrible and only in the last couple days do I feel stable. Is this normal with first taking it?

thanks folks, I have many more questions but I don't want to bombard you all in one thread.

Nathan
