It shows that what you are taking is getting to your blood just fine. That means that you do not malabsorb severely. You may or may not eventually.

It also shows that the test measured a whole lot of B12 in the blood that had not been stored and would go out with the urine. Unless the test is done at least a few days after B12 is stopped, the test result is extra skewed.

I would take the methylcobalamin.
