Both deliver B12. Only one of them skips the part of the process that fails for a lot of people.
| What changes | Prescription injection | Oral supplement |
|---|---|---|
| How it reaches you | Injected under the skin, so it skips the digestive tract | Swallowed, then absorbed through the stomach and small intestine |
| What can get in the way | Nothing between the dose and the tissue | Stomach acid, intrinsic factor, gut health, and some medications |
| Active form | Methylcobalamin, a biologically active form of B12 | Varies by product, often cyanocobalamin |
| Routine | One injection on the schedule your provider sets | A tablet every day, indefinitely |
| Who decides the dose | A licensed provider, from your symptoms, diet, and prior labs | Whatever the bottle on the shelf says |
Absorption depends on your own diet, medications, and gut health. A licensed provider reviews those before deciding whether an injection is the right route for you.

An over-the-counter bottle cannot look at your diet, your medications, or your last B12 result. A licensed provider can, and does, before this ships.
Your vial is compounded in the United States against a prescription written for you, which is why the label carries your name, your active, and your strength. A shelf bottle answers to none of that.
What B12 does
B12 is a cofactor in the reactions that turn food into usable energy. Low B12 can read as fatigue and weakness.
B12 is required for normal red blood cell production and the oxygen-carrying work those cells do.
B12 helps maintain the myelin around nerve cells and supports normal neurological function.
Methylcobalamin is a biologically active form of B12. Rebody delivers it as a prescription injection.


B12 results
“My labs showed low B12 and the doctor recommended weekly shots. After a few weeks I have more energy after work and am not going directly to the couch every day. Rebody included everything I needed with the first shipment.”
“My B12 was low and I felt terrible every afternoon by the time I picked up my daughter. Four weeks into the shots, I am getting through work and daycare pickup without crashing on the couch. My Rebody doctor explained the lab results clearly, and the shipment included all the supplies.”
“I eat mostly plant based, so low B12 was not a surprise. What surprised me was how much better I felt after starting the injections. Seven weeks in, I am running before work a few times a week instead of turning around after the first mile.”

Methylcobalamin B12
Know the form, strength, vial size, supply, price, and prescribing process before you begin.
Methylcobalamin is a biologically active form of vitamin B12. Rebody offers it as a prescription injection compounded by Strive Pharmacy, a licensed 503A compounding pharmacy in the United States, with the active ingredient, strength, and vial size stated on the label.
Methylcobalamin 5 mg/mL in a 10 mL vial. The package is designed as an approximately 60-day supply. Your prescription label carries your final dose and directions.
An injection puts the dose into the tissue rather than through the digestive tract. That matters when diet, medication use, or an absorption problem is part of why B12 is low. Your provider reviews those factors before prescribing.
They are different forms of vitamin B12. Rebody prescribes methylcobalamin, which is a biologically active form. Many over-the-counter tablets use cyanocobalamin instead.
Your prescriber sets the dose and frequency from your health history. Follow the directions on your prescription label and message your care team before changing your schedule.
The displayed package price includes the online provider review, medication when prescribed, injection supplies, and free discreet shipping. The first shipment carries about two months of treatment.

Seek urgent care for signs of a serious allergic reaction, including trouble breathing, facial swelling, severe dizziness, or fainting. Do not share your vial or injection supplies.
