Thank you everyone for your thoughts and ideas. I do eat a variety of fresh organic foods, eat nuts, beans, etc. so I'm trying to keep my diet healthy and varied withing the restrictions I have. My B12 has tested normal but maybe supplementing with small amounts would be useful to try. I think there are 2 different types of B12? Is there one that is preferable to another? In the past I tried sublingual methyl B12.
If your doctor did an ordinary B12 test is won't be reliable in that it lumps together all the B12 values--the ones that are functional and useful to our bodies and the ones that are not. If if is broken down into the different types, many of us who test normal or high on B12 are functionally deficient. Most doctors don't know the difference.
And yes there are many types of B12 you can take through different routes and doctors will usually give you cyanocobalamin which takes several conversions to become bioactive. Some of us have genetic errors that prevent those conversions. Also, cyano has a by-product of cyanide which some people can efficiently process and remove from the body.
So it is better to take one of the active forms of B12 and it cannot be swallowed (B complex pills have you swallow it) or most of it is lost in digestion. It needs to be taken sublingually or by injection.
There has been a lot of discussion here about whether to take methyl B12 or hydroxy B12 with good arguments on either side. My doctor has me injecting hydroxy as do many ME/CFS doctors.
You can read a great deal more about this on the very long B12 thread!
Best wishes,
