Question 4

how long does it take b12 injections to work?

Question 5

why do i feel very unwell after b12 injection, help?

Accepted Answer

Probably: Means that you needed it and that you need more after the symptoms improve. Giving vitamins to people is different than drugs because they often make symptoms temporarily worse before they improve. You do not need to worry over side effects at all.

Question 6

could i still take a b12 injection if it is expired by 6months?

Accepted Answer

Expired meds: Two sides to this answer -   the "legal" side  - no - medications have expiration dates for reasons  of potency and sterility.   Over time medicatons lose their potency and if it is a multiple dose vial - the issue of sterility comes into play.     Now the "practical" answer - yes- if the vial was only used for you and the fluid appears clear it should be safe to use - the potency may be diminishe.

Question 7

which is the best b12 injection with all necessary composition?

Accepted Answer

Why injection?: Unless you have demonstrated inability to absorb B12, taking B12 orally will be just as useful. If you are not deficient in B12, taking more will not do you any good.

Question 8

i just took a b12 injection. how long does it stay in your system.

Accepted Answer

The answer: depends on your own individual metabolism and your dietary habits.  If you eat a lot of processed foods, chances are the chemicals contained within these products will interfere with your intestinal absorption of this vitamin.  Injections bypass that problem.   Most injections last about a month on average.  The amount of B12 in your body also depends on how much is stored by your liver .

Question 9

can you overdose with too many b12 injections?  what symptoms would get?

Accepted Answer

No: There have been no reported overdoses using b12.

Question 10

what is the difference in how b12 is metabolized between injections and pill forms?

Accepted Answer

Muscle vs GI: The injection goes into a muscle and is directly absorbed into the blood.  This is the preferred route for people with absorption problems. The oral route or pill form may not be well absorbed if there is stomach conditions- like pernicious anemia, or intestinal issues like crohns. These patients due to their inflammation would benefit from a intramusclar shot.
