I have raynauds and high b12. I don't understand the correlation and nor does my internist

As far as I can tell from about 10 minutes googling there is no direct correlation between raynaud's disease and high b12 levels. In a healthy and normal person a vitamin b12 defeciency could produce symptoms similar to raynaud's disease. Now here is where the connection could come. A vitamin deficiency comes when there isn't enough of a particular vitamin for the body to use and because of this the products and process that involve that vitamin can't run. There are two ways you can have a deficiency, the first is obviously that you don't have enough of that compound in your system but the second is that the machinery that initially process that compound is broken. The latter would have an high level of that particular compound while the former wouldn't. A metaphor, you have an ice maker but you're getting no ice. You could have two problems, there is no water for the ice maker and thus the ice make would be dry, or your ice maker could be broken and therefore soaked in the water it couldn't use.

The skinny of it is that you should get tested to see if you're using the b12 vitamin. You body could be unable to process it leaving it in a state similar to those who are deficient in the vitamin.
