Anyone had the above combo? I am so tired of chasing around this B12 ghost. I have exhausted just about all the tests, but still my B12 is moderately out of range, around 1300, but MMA is within range 174 with upper range being 376. Also urine homocysteine showed it extremely low. I don't remember the value, but it was waaaay below 0. Any thoughts on what can be keeping my B12 moderately elevated?
