Cyanocobalamin Generic Name: What It Means and Why It Matters
Seen "cyanocobalamin" on a prescription or supplement label and wondered if that's a brand or a generic term? Here's the quick answer — plus what it means for your B12 options.
If you're searching for the cyanocobalamin generic name, here's the short version: cyanocobalamin is the generic name. It's not a brand — it's the official, nonproprietary term for a specific synthetic form of vitamin B12.
That said, the longer answer is more useful. Understanding what cyanocobalamin actually is, which brand-name products contain it, and how it compares to other B12 forms can help you make sense of what's actually in a supplement bottle or an injection vial.
This guide covers all of that — including why AliveDrip's physician-directed team, at our Montclair and Wayne, NJ locations, uses a different form of B12 in our injections and IVs.
What You'll Learn
Quick Answer: Is Cyanocobalamin a Generic Name?
Yes. Cyanocobalamin is the official generic (nonproprietary) name for a synthetic, cyanide-bound form of vitamin B12. According to NCBI's StatPearls clinical reference, it's FDA-approved for pernicious anemia, malabsorption-related deficiency, atrophic gastritis, and related conditions, and it's sold both as a generic and under several brand names.
The name itself is descriptive: "cyano-" refers to the cyanide group attached to the cobalamin (vitamin B12) molecule, which is what makes this particular form chemically stable and inexpensive to manufacture.
Understanding the cyanocobalamin generic name also helps explain why pricing and packaging can look so different from product to product. Since no single company holds exclusive rights to the ingredient, manufacturers are free to package and market it under whatever name they choose — which is exactly how it ends up under a dozen different labels on pharmacy shelves.
Brand Names That Contain Cyanocobalamin
Because cyanocobalamin is a generic ingredient, it shows up under many different product names depending on the manufacturer and formulation:
- Nasal spray: Nascobal, CaloMist
- Injectable: Cyanoject, Rubramin PC, Crystamine, Redisol, Betalin-12, Cobolin-M, Berubigen (historical)
- Oral/sublingual: Vitamin B-12, B-12, various store-brand supplements
Many of these older injectable brand names are no longer widely manufactured, and most cyanocobalamin products sold today are simply labeled with the generic name rather than a proprietary one — which is often exactly why the question comes up in the first place.
What Cyanocobalamin Actually Is
Cyanocobalamin doesn't occur naturally in food. It's a lab-synthesized version of vitamin B12, typically produced through controlled bacterial fermentation and then chemically stabilized with the cyanide group that gives it its name. This manufacturing process is what makes cyanocobalamin so shelf-stable and affordable compared to naturally derived cobalamin forms — a major reason it became the industry-standard generic decades ago and remains one of the most widely available forms of B12 today.
Once it's absorbed, your body has to do some work to make it useful: enzymes strip away the cyanide group and replace it with either a methyl group or an adenosyl group, converting it into one of the two active coenzyme forms your cells actually use.
This conversion step is well-tolerated by the vast majority of people and has been the basis of B12 supplementation for decades. It's also the main point of comparison against forms like methylcobalamin, which arrive at your cells already in a usable, active form.

| Cyanocobalamin | Methylcobalamin | |
|---|---|---|
| Origin | Synthetic | Naturally occurring active coenzyme form |
| Needs conversion? | Yes — cyanide group must be enzymatically removed | No — used directly by cells |
| Stability | Very stable; long shelf life | Less stable; sensitive to light and heat |
| Cost to produce | Lower | Higher |
| Typical use case | General supplementation, widely available generic | Preferred by many physician-directed providers for direct cellular use |
The Cyanide Question, in Context
The word "cyanide" understandably raises eyebrows, so it's worth putting in perspective. A typical 1,000 mcg cyanocobalamin dose releases roughly 20 micrograms of cyanide during conversion — your body neutralizes this almost instantly through a normal detoxification enzyme. For comparison, a single apple contains far more cyanide-related compounds than that. At standard supplement and injection doses, this isn't considered a meaningful safety concern for most people.
Who Should Be More Cautious
That said, there are two specific groups where clinicians tend to prefer a different B12 form over cyanocobalamin:
- Advanced kidney disease — the small amount of cyanide released is cleared more slowly, so it can accumulate with repeated dosing
- Leber's hereditary optic neuropathy — a rare inherited condition where cyanocobalamin is specifically cautioned against, since it may worsen optic nerve damage
Outside of these specific situations, cyanocobalamin is considered safe and is used in millions of doses every year. If either applies to you, it's worth discussing your B12 form directly with your physician.
Why AliveDrip Uses Methylcobalamin Instead
A Note on Formulation Transparency
AliveDrip's B12 injections and IV add-ons are formulated with methylcobalamin, not cyanocobalamin. If you came here specifically looking for a cyanocobalamin product, that's not what we offer — and we'd rather tell you that upfront than have you find out at check-in.
Our physician-directed team chose methylcobalamin because it's already in the active coenzyme form your cells use directly, without requiring the conversion step cyanocobalamin needs. For a wellness clinic focused on immediate-use IV and injectable delivery, that fits the physician-directed, personalized approach we build every protocol around — formulated through FDA-registered compounding pharmacies for quality and dosing accuracy.
You can see how methylcobalamin fits into our broader offerings on our IV NAD+ page, or explore the full IV drip menu, which includes B12 as a standalone booster or combined into several formulations.

Book a ConsultationWhich B12 Form Might Be Right for You
- Cyanocobalamin is a reasonable, well-studied, cost-effective choice for general oral supplementation in healthy adults without kidney or optic-nerve conditions.
- Methylcobalamin is often preferred for physician-directed injectable or IV protocols, since it skips the conversion step and is favored by providers focused on direct cellular delivery.
- Hydroxocobalamin is more commonly used in Europe and is the form used to treat cyanide toxicity itself — not typically found in wellness clinic settings.
The "best" form really depends on your goals, how you're taking it, and any underlying health conditions. Knowing the cyanocobalamin generic name and what it actually contains is a good first step — the next is a physician-directed conversation rather than guessing from a supplement label.
Key Takeaways
- Cyanocobalamin is itself the generic name for a synthetic, cyanide-bound form of vitamin B12 — not a brand.
- Brand names like Nascobal, Cyanoject, and Rubramin PC contain cyanocobalamin, though most products today are simply labeled generically.
- Cyanocobalamin requires enzymatic conversion before your body can use it; methylcobalamin is already in an active, usable form.
- The cyanide released during conversion is negligible for most people, with specific caution warranted for advanced kidney disease or Leber's hereditary optic neuropathy.
- AliveDrip formulates its B12 injections and IVs with methylcobalamin, not cyanocobalamin — worth knowing before you book if you were specifically looking for the latter.
Frequently Asked Questions
Cyanocobalamin is the generic name for one specific synthetic form of vitamin B12 — not for B12 as a whole. Vitamin B12 is a family of related compounds (cobalamins), and cyanocobalamin, methylcobalamin, hydroxocobalamin, and adenosylcobalamin are all different generic forms within that family.
Common brand and product names have included Nascobal, CaloMist, Cyanoject, Rubramin PC, Crystamine, Redisol, Betalin-12, and Cobolin-M, among others. Many of these are legacy names, and most cyanocobalamin products on the market today are labeled with the generic name directly.
Yes, for the vast majority of people. It's FDA-approved and has been used safely for decades. The trace amount of cyanide released during conversion is far below any harmful threshold. The main exceptions are people with advanced kidney disease or Leber's hereditary optic neuropathy, who should discuss B12 form with their physician.
No — AliveDrip's B12 injections and IV add-ons use methylcobalamin, the active coenzyme form of B12, rather than cyanocobalamin. Our physician-directed team chose this formulation for direct cellular use without a conversion step. If you have questions about which form fits your goals, our team can walk you through it during a consultation.
Because cyanocobalamin is the generic name rather than a trademarked one, any manufacturer can produce and sell it under its own product name. That's why you'll see it marketed as Nascobal, plain "Vitamin B-12," store-brand supplements, and older discontinued injectable brands — they're all built on the same underlying generic ingredient, just packaged differently.
