Im taking b12 vitamins is 500mcg enough im 25yrs recomended daily dosage?i used to get shots but i want to see how i do with the pill which is better?

Sublingual B12: Is best. Get the kind that melts under your tongue and with folate (folic acid) if possible. 500 to 1000 mcg is a common dose. If you swallow the B12 you will get much lest benefit because it has to go through your GI system. Peace and good health.

Listen to your body: Methyl cobalamine 500 mcg in a chewable or sublingual from should work well. If you have trouble with UTI 's or skin infections remember that bacteria also like b-12. How was it determined that you were b-12 deficient? May be you are under stress and losing b-12 or deficient in stomach acid and not making intrinsic factor. It is helpful to know cause of deficiency and treat the cause, too.
