Product contextClinical information,
Clinical information,
with clear sources.
The treating clinician determines suitability and prescribing. Product-specific labeling and pharmacy guidance remain essential.
Vitamin B12 has roles in red blood cell formation and nervous system function. Cyanocobalamin and methylcobalamin are forms of B12; treatment decisions depend on the patient and exact preparation. NIH: vitamin B12 fact sheet
Review deficiency and product-specific use.
Cyanocobalamin injection is used to treat or prevent B12 deficiency in specified circumstances. That product context should not be applied automatically to every B12 listing. The clinician should review the cause of deficiency, medical history and product-specific precautions. MedlinePlus: cyanocobalamin injection
Confirm whether the exact product is an approved medicine or a compounded preparation. Compounded drugs are not FDA-approved and do not undergo FDA premarket review for safety, effectiveness or quality. FDA: compounded drug information

Useful answers
Vitamin B12 ordering FAQs.
What your team needs to know about access, product options and ordering.
Contact & supportWhich vitamin B12 preparations are listed?
The catalog contains eight B12 entries across Kaduceus, Emerald, Boothwyn and Optimal. Cyanocobalamin and methylcobalamin are identified separately. One Kaduceus entry states B12 without identifying the chemical form.
Are cyanocobalamin and methylcobalamin the same preparation?
They are different forms of vitamin B12. Confirm the exact ingredient, concentration, route and prescribing requirements rather than substituting based on the B12 family name.
Are all the listed products injections?
The Boothwyn entries explicitly say injectable solution. The other source names do not consistently establish dosage form and route, so those details require pharmacy confirmation.
Why do some package details need confirmation?
Some source entries have missing concentrations or conflicting package-volume wording. Confirm the exact specification with the pharmacy; no value should be inferred from a conflicting listing.
Is concentration the same as total vial content or a dose?
No. Concentration is an amount per volume. Package volume and total content are separate product values. The clinician determines the prescribed dose; this page provides no conversions or administration instructions.
Are MIC / B12 and Lipo blends included on this page?
Those are multi-ingredient preparations and have a separate Lipo / MIC product family in Wellness & Nutrition. This page covers the eight standalone B12 catalog listings.
Does a B12 listing establish a benefit for every patient?
No. Treatment suitability depends on clinical assessment and the exact product. This page does not promise increased energy, weight loss or other outcomes.
Can my clinic review pricing and order online?
Approved clinic accounts can review current pharmacy information, availability and account pricing. Patients should contact their treating clinician about prescriptions and treatment.
How can my clinic contact CoreLink?
