Re: vitamin b12 low
vitamin B12 can deffinitley cause the symptoms you're experiencing.
there are a few different types of B12, the most common form is cyanocobalamin,
i would recommend that you invest in a multivitamin, that will help replenish your B12 levels.
if that doesnt work, go to a health store and look for a product called "methylcobalamin"
it is the most bioavailable form of B12
