How much is a B12 shot in Toronto?

$60 for a 5,000 mcg methylcobalamin injection, or $40 for the 1,000 mcg maintenance dose. Five-packs are $270 and $180 respectively.

Do I need a referral or a prescription for a B12 shot?

No. You can book a B12 shot directly with us.

Do I need bloodwork before a B12 injection?

Not for B12. Testing is useful if you want the dose and interval matched to your actual level, and we can arrange it, but it is not a requirement before your first shot.

Methylcobalamin or cyanocobalamin — does it matter?

We use methylcobalamin. It is the active form, so your body does not have to convert it first. Cyanocobalamin is cheaper and more common, which is why most walk-in clinics use it.

B12 Injections at Upper Room Clinic

Vitamin B12 is what your body uses to build red blood cells, insulate nerves, and run the methylation reactions behind energy and mood. It is absorbed in the last stretch of the small intestine, and getting it there needs stomach acid and a protein called intrinsic factor. When any link in that chain breaks, oral B12 stops being reliable no matter how large the tablet — which is why an injection is often the more dependable route. Every shot at Upper Room Clinic, at both our Toronto and Oakville locations, is given by clinical staff under physician oversight.

B12 deficiency creeps in slowly and gets blamed on stress, age, or a busy life. Fatigue that sleep does not fix, brain fog, pins and needles in the hands or feet, a sore tongue, low mood. Long-term metformin, proton pump inhibitors and H2 blockers all deplete it — and the risk compounds when they are taken together. So do bariatric surgery, bowel resection, celiac disease, Crohn's, and a fully plant-based diet without reliable supplementation. A simple blood test is all it takes to find out where you stand.

Methylcobalamin, not cyanocobalamin. The active form, so your body does not have to convert it first — cyanocobalamin is cheaper, which is why most walk-in clinics use it.
Two doses. 5,000 mcg to correct a deficiency, 1,000 mcg to maintain it once your levels are where they should be.
$60 and $40 per shot — or five for $270 and $180. Most people run a short course rather than a one-off, which is why both are offered as five-packs.
No referral, no prescription, no membership. Bloodwork is optional and useful if you want the dose and interval matched to your measured level rather than estimated.

Why the Form of B12 Matters

MTHFR is the enzyme that makes the active folate your body needs to run methylation. The common C677T variant reduces that enzyme's activity, which raises homocysteine and leaves less methylation capacity in reserve. It is not rare — roughly four in ten people carry one copy, and around one in ten carry two. The people who carry it are often exactly the people who end up needing B12 injections.

Cyanocobalamin, the cheap synthetic form used by most walk-in clinics and in food fortification, is not a form your body uses directly. It has to be stripped of its cyanide group and converted first, and that conversion draws on the same methylation capacity an MTHFR variant has already reduced. Cyanocobalamin occurs in human tissue only in trace amounts; methylcobalamin, adenosylcobalamin and hydroxocobalamin are the forms your physiology actually runs on, and the review literature recommends those bioidentical forms over cyanocobalamin — particularly where a genetic variant affects how B12 is assimilated.

We use methylcobalamin at both locations. It is the active form, so nothing has to be converted before your body can use it. If you already know your MTHFR status, tell us when you book. If you do not and you would like to, we can arrange the genetic testing that identifies variants affecting methylation.

The Benefits

Because an injection bypasses the gut, it does what tablets often cannot — deliver a known dose, reliably, regardless of how well you absorb.

Absorption stops mattering. No stomach acid, no intrinsic factor, no intact terminal ileum required.
A known dose, every time. What we give is what you get — unlike an oral tablet, where the fraction absorbed varies enormously between people.
Minutes, not an afternoon. There is no line and no chair time; the injection itself takes moments.
The active form. We use methylcobalamin rather than cyanocobalamin, so your body does not have to convert it first.
Physician oversight, and labs if you want them. We can requisition the bloodwork, match your dose to your measured level, and send results to your family doctor.

ONGOING & PRICING

Book directly — no referral and no prescription needed. You get portal access when you book, so upload any recent bloodwork and we will match your dose to your measured level rather than estimating it. There is nothing to prepare and no need to fast. If you already know your MTHFR status, tell us at this stage.

Methylcobalamin is injected into the muscle of the upper arm by our clinical staff, under physician oversight. The injection itself takes moments, and most people are in and out well inside fifteen minutes. We use the active form, so nothing has to be converted before your body can use it.

You can drive yourself home and go straight back to your day. Some people notice more energy within days; where levels were genuinely low, the fuller benefit builds over several weeks as your body makes new red blood cells and nerve symptoms settle.

$60 for the 5,000 mcg correction dose and $40 for the 1,000 mcg maintenance dose, or five for $270 and $180. Most people run a short course at a set interval rather than a single shot. Where it is useful we recheck your level, step you down to maintenance, and send results to your family doctor.

During Treatment

Methylcobalamin is given intramuscularly into the upper arm by our clinical staff, under physician oversight. The injection itself takes moments and most people are in and out well inside fifteen minutes. There is no line and no chair time. You can drive yourself home and go straight back to your day.

Why Choose Upper Room Clinic

B12 therapy at Upper Room Clinic is overseen by Dr. Biljana Kostovic, a physician with over 30 years of clinical experience spanning emergency medicine, pain medicine and integrative care. That matters more than it sounds. Fatigue, brain fog and neuropathy have a long list of possible causes, and a clinic that can only sell you a shot will sell you a shot. We can requisition the bloodwork, read it in context, and tell you when B12 is not the answer.

With locations in Davisville, Toronto and Oakville, you do not need a referral to be seen — though it is highly beneficial to share your family doctor's information with us, so we can coordinate bloodwork, share your results, and keep your GP in the loop. Book directly for a straightforward shot, or start with a wellness intake if you want the dose and interval matched to your measured level — in a monitored, physician-led medical clinic rather than a walk-in drip lounge.
