Karen,

All that may be true for you. Assuming that you do react very quickly to changes in B12 doses, you are in a tiny minority. It is very important that people not believe that "B12 is effective in a way that can be felt pretty quickly." A very small minority find that.

And although there may be something else going on, one size does not fit all in the change of symptoms department either. As a matter of fact, a small minority do not see evidence of the great changes going on in their bodies for many months.

When people assume that there will be short-term differences if they are benefitting from B12, they are in danger of stopping even though they need it. This is very dangerous if the person needs it.

People can take B12 long enough to get their stores up good and strong and then stop. If their body has been working on that stored B12, they may see a positive change after they stop. If they do not realize that most people store B12 for a long time and use it very slowly, they will decide they do not need the B12, even though the B12 is the reason for their improvement.

Those people are then likely to stop taking B12 altogether and eventually (within months or years) begin to incur damage again.

One size does not fit all. Most people do not see those immediate and linear changes that correlate with B12 taken in the short term.
