Vitamin B12 IM

Cobalamin Delivered Directly into the Muscle for Complete Absorption. Support Red Blood Cell Production, Neurological Function, and Cellular Energy

DURATION: Approximately 5 minutes
B12 shot package treatment for energy and wellness support at Vitality IV

Quick Benefit Highlights

  • Energy That Comes from the Cell, Not a Stimulant: B12 is essential for ATP production in the mitochondria, the cellular energy currency that powers every organ, muscle, and thought. This is metabolic energy at its source, not a caffeine spike
  • Red Blood Cell Formation and Oxygen Delivery: B12 is required for the synthesis of healthy red blood cells. Without it, cells become large and dysfunctional, reducing the amount of oxygen your blood can deliver to muscles, organs, and the brain
  • Neurological Health and Myelin Protection: B12 is required for myelin synthesis — the protective coating on nerve fibers that enables fast, accurate signal transmission throughout the nervous system. Depletion leads directly to cognitive slowing, numbness, and mood disruption
  • Better Absorbed Than Any Oral Supplement: Most people absorb a fraction of the B12 in supplements and fortified foods due to the intrinsic factor dependency that governs gut uptake. IM injection bypasses this completely — the full dose reaches your bloodstream directly

Service Description

The Most Requested Injection on Our Menu. Here Is Why.

Vitamin B12 is one of those nutrients where the gap between how much you take and how much you actually absorb can be enormous. Unlike most vitamins, B12 cannot simply diffuse through the intestinal wall. It requires a carrier protein called intrinsic factor, produced by specialized cells in the stomach lining, to bind to it and escort it through to absorption. If intrinsic factor production is inadequate (which becomes increasingly common after age 40, with certain medications, and with any history of digestive issues), the B12 you take orally largely passes through unused.

This absorption limitation is why B12 deficiency and insufficiency are among the most underdiagnosed nutritional problems in adults. The symptoms, which include fatigue, brain fog, mood changes, tingling in the extremities, and poor memory, are common enough that most people attribute them to stress, aging, or simply not sleeping well. In many cases, the underlying cause is a chronic shortfall in a vitamin that the body has no reliable way to store or replace through diet alone when gut absorption is compromised.

Intramuscular injection eliminates intrinsic factor dependency entirely. The full dose of B12 enters the muscle tissue directly and absorbs into the bloodstream with complete bioavailability. It is one of the fastest and most reliable ways to raise serum B12 levels, making it an effective option for supporting energy production, cognitive function, and overall wellness. B12 can be booked as a standalone intramuscular injection or added to a bag of normal saline during an IV infusion. It cannot be administered as an IV push.

Ideal For:

  • Anyone experiencing persistent fatigue, brain fog, or low mood that does not resolve with adequate sleep or lifestyle adjustments
  • Vegans and vegetarians, for whom B12 has no reliable dietary source and supplementation is a non-negotiable necessity
  • Adults over 40, as intrinsic factor production and gastric acid levels that facilitate B12 release from food both decline with age
  • Clients taking metformin, proton pump inhibitors, H2 blockers, or other medications known to deplete or impair B12 absorption
  • Anyone with a history of Crohn’s disease, celiac disease, gastric bypass, or other conditions affecting GI absorption
  • Athletes and active individuals who want reliable energy and recovery support without stimulants or additional supplements
  • Clients who want a fast, meaningful wellness upgrade that fits into any schedule — standalone or alongside any IV infusion

How You’ll Feel:

Many clients notice a lift in energy and mental clarity within 24 to 48 hours of their first B12 injection. Those with meaningful deficiency or insufficiency often describe a more pronounced shift over the first few sessions: steadier energy throughout the day, improved mood, sharper focus, and a noticeable reduction in the afternoon fatigue that had become their baseline. For clients who use it consistently, B12 is frequently described as the wellness habit that makes every other part of their routine work better.

Service Details

What to Expect: Your Session

  1.  Brief Check-In – Your nurse confirms your current health status, any medications that may affect B12 levels, and whether you are booking as a standalone or adding to an infusion. Takes just a moment for returning clients.
  2. Injection or IV Add-On (Approx. 5 Minutes) – As a standalone, your B12 is delivered as a quick IM injection — a brief pinch and it is done. As an IV add-on, it is administered as a push through your existing catheter during your infusion session with no additional needle.
  3. You’re Done – No downtime, no restrictions. Walk straight back to your day. Many clients schedule their B12 on the way to the office, between errands, or as a quick stop before the gym.

Absolutely amazing experience. Kind, caring and knowledgeable. I was having an issue where I became extremely dehydrated and needed IV fluids. They also have zofron ( for nausea) wich is amazing. If you have ever needed it you know. I can't recomend them enough. Invest in yourself as I immediately felt better after my IV bag. Very clean,nice,convenient location. You can sit & relax in a recliner while your IV drips or they have a private room in the middle. The price is pretty good especially considering it against perhaps an ER visit. I highly recommend this place. You won't be disappointed.

First class service and very extensive infusion options. I found them out at a pickle ball tournament taking care of us players, giving out some free IVs and B-12 shots, which was greatly appreciated in the heat. I played my next match feeling 100 percent again post IV. Thanks again, Mindy! You’re amazing at what you do!!
