Vitamin B-12 is an essential nutrient required for healthy red blood cells, neurological function,
and DNA formation. It is a water-soluble vitamin also known as cobalamin. People who are
deficient in vitamin B-12 are often prescribed to take a B-12 injection because the shot allows
for 100 percent absorption directly into the tissue. This method is very effective at reversing or
preventing a B-12 deficiency.

Benefits for taking a B-12 injection:
● Helps to improve sleep.
● Increases energy levels and fights fatigue.
● Increases concentration.
● Improves mood.
● Boosts the immune system.
● Speeds up metabolism and helps with weight loss.
● Reverses hair loss.
● Helps to prevent anemia.

Having a vitamin B-12 deficiency is becoming increasingly common because more and more
people are converting to a vegetarian or vegan lifestyle. Eliminating food sources that contain
B-12 such as meat, eggs, and dairy products can make you vulnerable to developing a B-12
deficiency. Although, some meat eaters who don’t absorb vitamin B-12 well can also end up
developing a deficiency. This is when a B-12 injection can be extremely beneficial.
Vitamin B-12 injections can be self-administered, but the safest way is to have a trained
healthcare professional give the injection. There are four possible injection sites on the body to
choose from. The ideal site is dependent upon the age and comfort level of the person giving
you the shot.
Injection sites:
Upper arm. This injection site is used for young or middle-aged adults. But an older
adult whose muscles in this area are well developed can also take the shot here too.
Buttocks. This injection site is on the upper outer buttock area on either side of the
body. Only a professional should administer the injection in this site because it is
located close to major blood vessels and sciatic nerve. If the vitamin B-12 injection
were to be given incorrectly, the blood vessels and sciatic nerve could be damaged.

Outer hip. This injection site is used for children as young as7 months old to adults.
Most professionals prefer this area because there are no blood vessels or nerve that
could get damaged from the shot.
The thigh. This injection site is used mostly by people who administer the injection
themselves as well as infants or small children.
There are two types of B-12 injection methods that can be used, intramuscular and
subcutaneous. Their procedure and effectiveness vary between the two methods.
Intramuscular injection – this is the more common injection used which tends to
produce safe and effective results. The needle is inserted at a 90-degree angle deep
into the muscular tissue. As the vitamin B-12 is administered, it is absorbed
immediately by the surrounding muscle.
Subcutaneous injection – this type of injection is inserted just below the skin instead of
into the muscle. The needle is inserted at a 45-degree angle which the outer skin may
be pulled away to ensure the needle does not puncture the muscle. The upper arm
area is the best site for this type of injection.
If you are having a B-12 injection administered, always make sure that the site chosen is
exposed and cleaned with rubbing alcohol in a circular motion. Allow the site to dry before
giving the shot.

● Clean the surface of the B-12 vial with rubbing alcohol and a new cotton ball.
● Turn the vial upside down and remove a clean needle from its package.
● Take the safety top off the needle and insert the needle into the vial pulling the
syringe back to the desired amount to inject.
● Remove the needle from the vial and give a slight push to expel a small amount of B-12
to make sure the air is out of the syringe.
● Using the thumb and forefinger to hold the skin, administer the B-12 injection pulling
the plunger back just a little to make sure there is no blood in the syringe.
● Continue administering the B-12 solution then let go of the skin to remove the needle
at the same angle it was inserted.
● Wipe the injection site in a circular motion and then apply a band-aid.
● Dispose of the needle properly because disposable needles should be used only once.
● Store any unused B-12 injection solution at room temperature away from moisture,
heat, and light.
