About Vitamin B12 You’ve probably heard that vitamin B12 is an effective energy booster. But this amazing nutrient does so much more! With weekly injections you can not only increase your energy and alertness, but also improve your memory, obtain more restful sleep, decrease stress and enhance your mood.

What are the benefits of B12 injections?

  • Increases metabolism, which may produce the side effect of weight loss
  • Boosts energy

How do I know if I have B12 deficiency?

Vitamin B12 deficiency is quite common and many people suffer from it without ever knowing. It’s estimated that 40 percent of people between the ages of 26 and 83 have a B12 deficiency.

Why can’t I take a vitamin B12 pill instead of the injection?

One of the biggest problems with vitamin B12 is that it is not easily absorbed by your body. Stomach acids that aid in the natural breakdown of food also breakdown oral vitamin B12 supplements, causing your body to only absorb approximately 1-4% of the vitamin in pills. Because of this, injections are the preferred option, as the B12 vitamin is completely absorbed into your bloodstream.

How long does vitamin B12 last in my body?

Vitamin B12 is a water-soluble vitamin. After your body uses the vitamin, any leftover amounts leave the body through urine. This process usually takes between 24 to 72 hours, depending on the amount of fluids you intake.

How often do I need to receive a B12 injection?

Due to the rapid rate with which the body processes B12, injections two times a week is needed to address any B12 deficiencies or weight loss goals. Patients who wish to use B12 injections for increased energy may be satisfied with receiving an injection only once a week.

Is it safe?

Vitamin B12 shots have been used for decades as a safe and effective treatment for vitamin B12 deficiency.  One wonderful property of vitamin B12 is that it is non-toxic and highly water soluble. This means that even if you take too much, any excess amount will simply leave your body through urine.

What are the side effects from a B12 injection?

A vitamin B12 injection is safe and generally has no side effects, even in higher doses. Some patients may experience mild redness and swelling at the injection site. Other side effects may include mild diarrhea, mild stomach pains, nausea, headaches, and joint pain. During your complementary consultation, our medical professional will review your history, previous conditions, and current medications to determine if you are at a higher risk for any side effects.

What should I expect during my B12 injection?

After your medical professional has completed your consultation, you can receive a B12 injection. B12 injections are administered into your muscle and usually delivered to your outer deltoid (buttocks). After the injection, most patients will start to feel a boost of energy within a few hours. Patients that are B12 deficient may experience a decrease in energy until they have been receiving the injections for a few weeks.

How long does it take for the B12 injection to take effect?

Vitamin B12 injections work differently for different people. You could easily start to notice positive changes from vitamin B12 starting in as little as a few days; however, you’re likely to experience better results after 60 to 90 days. Consistent use over time also improves effectiveness. For optimal results, make sure to receive an injection one to two times per week.
