WHAT IS VITAMIN B12?
An Essential Nutrient Your Body Can’t Make
Vitamin B12 helps your body turn food into energy, make healthy red blood cells, and keep your nerves and brain working properly. Your body can’t make B12 on its own, so it has to come from food or supplements.
Many people don’t absorb enough B12 from their diet, especially as they get older. A B12 injection goes into the muscle and bypasses digestion, so your body can absorb and use it consistently.
WHO IT’S FOR
Could a B12 Injection Help You?
B12 injections may be helpful if you have low B12 levels or are at higher risk. Patients often come to us because of:
Low Energy & Fatigue
Ongoing tiredness, low stamina, or feeling weak and run down.
Brain Fog
Trouble focusing, forgetfulness, or feeling mentally sluggish.
Plant-Based Diets
Vegan and vegetarian diets contain little natural B12, so supplementing is often needed.
Absorption Concerns
Aging, digestive conditions, weight-loss surgery, and some medications (like metformin or acid reducers) can lower B12 absorption.
BENEFITS
What B12 Injections May Support
B12 plays a part in many of your body’s everyday processes. When your levels are low, an injection can help with:
Natural Energy
B12 helps your body convert food into usable energy, without stimulants or caffeine.
Mental Clarity
Healthy B12 levels support memory, focus, and normal brain function.
Healthy Red Blood Cells
B12 is essential for making red blood cells that carry oxygen throughout your body.
Nerve Health
B12 helps protect your nerves and supports normal nervous system function.
Quick and Convenient
Each injection takes just minutes and pairs easily with IV therapy, nutrition support, or weight-loss care.
Good to know. Results vary based on your health, lifestyle, and B12 levels. If you’re not low in B12, extra injections may not make a noticeable difference, which is why we start with a consultation.
WHAT TO EXPECT
What to Expect at Your B12 Visit
1. Consultation. We review your symptoms, diet, health history, medications, and allergies. Lab testing may be recommended to check your levels.
2. Your plan. Your provider recommends how often to get injections based on your needs and goals.
3. A quick injection. A licensed clinical team member gives the injection into your upper arm muscle. It takes just a few minutes.
4. Back to your day. No fasting or downtime is needed. Mild soreness at the injection site is possible and usually goes away quickly.
5. Follow-up. We check how you’re feeling and adjust your schedule as needed.

FREQUENTLY ASKED QUESTIONS
B12 Injection Questions, Answered
What does a B12 injection do?
A B12 injection gives your body vitamin B12, which it needs to produce energy, make red blood cells, and support nerve and brain function. Because it goes into the muscle, it bypasses digestion and is absorbed consistently.
How often should I get a B12 injection?
It depends on your levels, symptoms, and goals. Many patients come in weekly or every other week, while others need them less often. Your provider will recommend a schedule after your evaluation.
How quickly will I feel results?
Some people notice more energy and focus within a few days. If your B12 was low, it may take a few weeks of regular injections to feel the full effect. Results vary from person to person.
Are B12 injections safe?
B12 injections are generally very safe when they’re given by licensed medical professionals. Common side effects are mild, such as soreness, redness, or swelling at the injection site. Allergic reactions are rare.
Who should not get a B12 injection?
B12 injections may not be appropriate if you’re allergic to cobalt or cobalamin, have Leber’s disease, already have very high B12 levels, or are pregnant or breastfeeding without your provider’s approval.
Do I need to prepare for my appointment?
No fasting is needed. Stay hydrated and tell your provider about all medications, supplements, and allergies.
Is a B12 injection better than a pill?
For people who absorb B12 well, pills can work. But aging, digestive conditions, weight-loss surgery, and some medications can make it harder to absorb B12 from your gut. Injections bypass digestion, so they’re a reliable option in those cases.
Is B12 included in a membership?
Yes. Our Signature Membership includes a monthly B12 injection, along with monthly Glutathione and NAD+ injections. See our Membership Program page for current details.
