I just want to add that keeping notes for ourselves is of the utmost importance, since not everyone is the same.

While 1000mcg of B12 may be perfect for one person, a younger person who is relatively healthy may thrive on 250mcg.

For me, with the severe depletion of my stores, probably related to the fact my mother had pernicious anemia, a B12 shot a month was helpful... but nowhere near as healthful as when the holistic M.D. I saw gave me a prescription for a B12 shot a day for a year.

Notes on your own condition and the changes in it in relation to specific symptoms that could be related to low B12 are your best bet to understanding your condition and improving it... if your condition is related to low B12.

And because nerves are at the bottom of a lot of health problems... low B12 contributes to a lot of ill health.

So, Take Notes!!!!!!!
