HelloPharmacist Scorecard of B-12 Blast Methylcobalamin 1000 mcg Raspberry Flavor by Bricker Labs

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: methylcobalamin, a form of vitamin B12. B12 is an essential vitamin your body uses for nerve function, red blood cell formation, and DNA synthesis.

The lozenge also contains inactive ingredients — sorbitol, fructose, natural fruit flavors, stearic acid, vegetable magnesium stearate, cellulose, and citric acid — that help form and flavor the tablet.

Does it work?

Not established
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Vitamin B12's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: supports nervous system and brain health.
  • We looked for evidence on: Age-related cognitive decline, Alzheimer disease, Cognitive function, Cognitive impairment, Dementia, Peripheral neuropathy — and 4 related terms.
  • The closest evidence on file: Vitamin B12 is rated "Possibly Ineffective" for Age-related cognitive decline (Natural Medicines).
  • Also on file: Vitamin B12 is rated "Possibly Ineffective" for Alzheimer disease, Circadian rhythm sleep disorders, Cognitive impairment.
  • Also on file: Vitamin B12 is rated "Insufficient Reliable Evidence To Rate" for Chemotherapy-induced peripheral neuropathy, Cognitive function, Dementia.

Vitamin B12 is effective for treating B12 deficiency and Imerslund-Grasbeck disease, a rare inherited condition that prevents B12 absorption. It's also likely effective for cyanide poisoning — a medical emergency.

For canker sores and postherpetic neuralgia (nerve pain after shingles), the evidence is less certain; B12 is possibly effective for these uses, meaning more research is needed.

The evidence, ingredient by ingredient Vitamin B12

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

B12 is generally well tolerated, and your body excretes excess amounts in your urine, so there's no established upper limit to worry about. Serious side effects are rare — the main one seen in studies is injection site reactions from B12 shots, not oral lozenges.

Allergic reactions like rash or itching are uncommon but possible; in one case, someone with a cobalt allergy developed a skin reaction to oral methylcobalamin. B12 is considered safe during pregnancy and breastfeeding at recommended doses, though talk with your provider about what's right for you.

Side effects, ingredient by ingredient Vitamin B12

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Vitamin B12.
  • The most serious interaction on file is rated Minor.
  • For scale: 20 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take metformin (Glucophage) for diabetes, this supplement can help offset B12 loss — but let your doctor know so they can keep an eye on your levels. No other medication interactions are documented for this product in our data.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Only minor medication interactions are documented, and safety information is well characterized.

This B12 lozenge is a solid choice if you're deficient in B12 or on metformin and want to maintain your levels. If you have a history of cobalt allergy or severe allergic reactions, flag that with your pharmacist first.

Run your medications through the checker before you start, especially if you take diabetes or heart medications.

B-12 Blast Methylcobalamin 1000 mcg Raspberry Flavor by Bricker Labs: Common Questions

Does B-12 Blast Methylcobalamin 1000 mcg Raspberry Flavor by Bricker Labs interact with any medications?
Yes. Based on its ingredients, B-12 Blast Methylcobalamin 1000 mcg Raspberry Flavor has a known interaction with 20 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
B-12 Blast Methylcobalamin 1000 mcg Raspberry Flavor contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Is B12 safe if I'm pregnant or breastfeeding?
Yes, B12 is considered likely safe during pregnancy and breastfeeding at recommended amounts. In fact, B12 is needed during both. Follow your provider's advice on dosing for your situation.
Can I take this if I have a cobalt allergy?
You should talk to your pharmacist or doctor first. B12 contains cobalt, and there's at least one case report of someone with a cobalt allergy developing a skin reaction to oral methylcobalamin.
I'm on metformin for diabetes. Should I take this B12?
Metformin can lower your B12 levels over time by interfering with absorption, so B12 supplementation can be helpful. Mention it to your doctor so they can monitor your B12 status and adjust if needed.
What are the common side effects?
B12 is very well tolerated. Allergic reactions like rash or itching are rare. Injection site reactions show up with B12 shots, not lozenges. Most people have no side effects at all.
Is there an upper limit to how much B12 I can take?
No. B12 has no established upper limit because your body gets rid of excess through your urine. You can't really overdose on it.
