Hi Paul,

First off

Doody mentioned that you found the vitmin forum and I will wander over there in a moment to read and catch up but if you are there you must have found Rose our B-12 champion and Mrs D one of the smartest folks here.

Each person is different and has different tolerances. I believe that methyl is the best form of B-12. But maybe now that you have restored your stores of B12 you can go to a lower maintenance dose.

I Know that low B12 and hashis go together. For Hashi's folks we want to try to keep our B12 blood levels at or above 1000.

I recently did two tests that were more accurate for b12 testing than blood serum levels. the first was Spectracell and the second was from B12tester.com.

I wish you the best of luck and hope you find some answers to your questions.
