Oral B12 is not
enough for most people.
Up to 40% of adults have suboptimal B12 levels — and most don't know it. Oral supplements are poorly absorbed, especially in patients with gut issues, low stomach acid, MTHFR gene variants, or anyone over 50.
Injectable methylcobalamin bypasses the digestive system entirely, delivering therapeutic concentrations directly into circulation — where your cells can actually use it.

Your body may be telling you something.
These symptoms are common — but they are not normal. B12 deficiency is one of the most frequently missed diagnoses in functional medicine.
Six reasons injectable B12
outperforms everything else.
Energy & Metabolism
B12 is essential for converting food into cellular energy. Deficiency is one of the most overlooked causes of chronic fatigue.
Cognitive Clarity
Methylcobalamin supports myelin sheath integrity and neurotransmitter synthesis — directly impacting focus, memory, and mood.
Injectable Absorption
Oral B12 is poorly absorbed — especially in patients with gut issues, MTHFR variants, or low stomach acid. Injections bypass this entirely.
Methylcobalamin Form
We use methylcobalamin — the bioactive, neurologically superior form — not cyanocobalamin, which requires conversion your body may not complete.
Lab-Guided Dosing
We check your serum B12, MMA, and homocysteine levels to confirm true deficiency and calibrate your protocol precisely.
At-Home Kit Available
Qualified patients receive a self-injection kit with full training — so you can administer your dose on your schedule, at home.
Not all B12 is the same.
A protocol built
around your labs.
We review your serum B12, MMA, homocysteine, and full metabolic panel to confirm deficiency and rule out other causes.
Your injection frequency, form (methylcobalamin or hydroxocobalamin), and dosing are calibrated to your specific deficiency level and goals.
Injections are administered in-clinic or via a self-injection kit with full training — whichever fits your lifestyle.
We recheck labs at 8–12 weeks to confirm repletion and adjust your maintenance protocol accordingly.
Frequently asked.
How often do I need B12 injections?
Most patients start with weekly injections for 4–8 weeks, then transition to monthly maintenance. Your protocol is based on your labs and symptom response.
Can I do this at home?
Yes. We provide a self-injection kit with full training for qualified patients. Subcutaneous B12 injections are simple, nearly painless, and easy to self-administer.
Do I need a consultation first?
Yes — we review your labs, symptoms, and health history before prescribing. B12 therapy is part of a broader evaluation, not a standalone add-on.
Is injectable B12 covered by insurance?
We are a cash-pay concierge practice. We do not bill insurance. Pricing is transparent and provided at your consultation.
What if I have the MTHFR gene variant?
Methylcobalamin is the preferred form for MTHFR patients since it requires no conversion. We test for this and factor it into your protocol.
Ready to feel like yourself again?
B12 deficiency is one of the most treatable causes of fatigue, brain fog, and low mood — and most people never get tested properly. Book a consultation and we'll find out exactly where you stand.
