I'm thrilled to hear of your experience.
Also, I want to say to you that it is common in people who are being damaged by B12 deficiency to begin to see some reaction to treatment after several days to two weeks.
However, those who do not see a reaction within that time should not assume that the B12 is doing no good. Rare people do not see a reaction for many months
, up to 18 months is documented.
People who do not malabsorb severely will get much more out of their oral dose, but those who malabsorb severely (lack intrinsic factor, stomach removed or bypassed, etc.) will only absorb about 1% of the large dose by default.
I use Jarrow.
Do visit my website in progress. I emphasize that it is new and under construction (I'm learning to create a site while creating it). Much more will be added, but some very important basics are on the pages that do exist there:
