B12 Injections
Vitamin B12: Are You Getting Enough?
Understanding B12 Deficiency, Digestive Absorption & Injection Therapy
Vitamin B12 plays an essential role in keeping your brain, nervous system, and red blood cells healthy. But even when you're eating a nutritious diet, your body may not always absorb enough of this important vitamin.
At Greystones Health, we take a closer look at the factors that may contribute to low B12 levels, from dietary intake and medications to digestive conditions that interfere with nutrient absorption.
If you're experiencing persistent fatigue, brain fog, tingling in your hands or feet, or other unexplained symptoms, our naturopathic doctors can help assess whether vitamin B12 deficiency may be contributing to how you feel.
Our goal isn't simply to give you an injection. It's to understand whether you need B12 supplementation, why your levels may be low, and which treatment approach is most appropriate for you.
When Digestion Affects B12 Absorption
Vitamin B12 has a unique absorption process that depends on healthy stomach function, intrinsic factor, and absorption in the final section of the small intestine, called the terminal ileum.
Certain conditions, including pernicious anemia, Crohn's disease affecting the ileum, atrophic gastritis, and previous gastrointestinal surgery, can interfere with this process.
For some patients, B12 injections provide an effective way to replace the vitamin without relying on digestive absorption. High-dose oral supplementation may also be effective, depending on the individual circumstances.
A Thoughtful Approach to B12 Treatment
At Greystones Health, B12 injections are offered as part of an individualized treatment plan. We review your symptoms, health history, and relevant laboratory results before recommending treatment.
Our aim is to help you make informed decisions about your health, with treatment recommendations that reflect your individual needs.

Why Is Vitamin B12 So Important?
Vitamin B12 is an essential nutrient that supports several important functions throughout the body. Although it is often associated with energy, its benefits extend well beyond fatigue.
-
Energy & Metabolism: B12 helps your body process nutrients and supports normal energy metabolism. Correcting a deficiency may help improve fatigue and weakness.
-
Brain & Cognitive Health: B12 plays an important role in healthy neurological function, including memory and concentration.
-
Nervous System: B12 is essential for maintaining myelin, the protective covering around nerves. Deficiency can contribute to tingling, numbness, and balance difficulties.
-
Healthy Red Blood Cells: B12 is needed for normal red blood cell production and helps prevent megaloblastic anemia.
-
Cellular Health: B12 supports DNA synthesis and healthy cell division.
Could You Be Low in Vitamin B12?
Vitamin B12 deficiency can develop gradually, and symptoms are sometimes mistaken for stress, aging, or other health concerns.
Some common signs include persistent fatigue, brain fog, difficulty concentrating, numbness or tingling in the hands and feet, muscle weakness, changes in mood, or problems with balance.
Certain people may be at greater risk of developing a deficiency, including those following vegan diets, older adults, individuals taking metformin or long-term acid-suppressing medications, and people with digestive conditions that affect nutrient absorption.
A blood test can help determine whether your B12 levels are low. Depending on your symptoms and results, additional testing such as a complete blood count (CBC) or methylmalonic acid (MMA) may be recommended.
It's important to recognize that neurological symptoms associated with B12 deficiency can occur even without anemia.
What Are the Benefits of B12 Injections?
Vitamin B12 injections deliver B12 directly into the body, bypassing the digestive absorption process.
This may be particularly beneficial for patients with significant absorption difficulties, such as pernicious anemia, certain intestinal conditions, or a history of gastrointestinal surgery.
When B12 deficiency is present, appropriate replacement may help:
-
Improve fatigue and low energy
-
Restore healthy red blood cell production
-
Support normal brain and nervous system function
-
Improve some neurological symptoms associated with deficiency
-
Prevent further complications of prolonged B12 deficiency
Some preliminary studies have also investigated B12 injections for chronic low back pain, with encouraging results.
B12 injections are not necessarily more effective than oral supplements for everyone. High-dose oral B12 can also be effective, even in some people with impaired absorption. The best approach depends on the underlying cause of deficiency and individual clinical needs.
What to Expect During Your B12 Injection Appointment
At Greystones Health, we aim to make your B12 treatment comfortable, convenient, and personalized.
Before beginning treatment, your naturopathic doctor will review your health history, symptoms, and relevant laboratory results to determine whether B12 injections are appropriate.
The injection itself takes only a few moments and is typically administered into a muscle in the upper arm. Most people tolerate the procedure well, although temporary tenderness or redness at the injection site may occur.
Your naturopathic doctor will recommend an injection schedule based on your individual needs and may suggest follow-up blood testing to monitor your response.
