HelloPharmacist Scorecard of Vegan B12 by DEVA
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
DEVA Vegan B12 contains 3 active ingredients. Vitamin B12 supports nerve function and red blood cell formation — your body needs it to convert food into energy and keep your brain working properly.
Vitamin B6 helps your body use proteins and produce neurotransmitters and red blood cells. Folate (also called vitamin B9) works with B12 to support cell division and DNA synthesis.
Together, these B vitamins are essential for energy, nerve health, and healthy blood cells. The tablet also contains several inactive ingredients — mannitol, xylitol, crospovidone, stearic acid, silica, lemon flavor, citric acid, sodium citrate, and vegetable magnesium stearate — which are used to form the tablet and improve its taste and stability.
Does it work?
Strong evidence
Vitamin B12 in this product is effective for treating B12 deficiency and is likely effective for cyanide poisoning. It's also possibly effective for canker sores and a nerve pain condition called postherpetic neuralgia.
Vitamin B6 is effective for sideroblastic anemia and B6 deficiency, likely effective for high homocysteine levels, and possibly effective for pregnancy-related nausea and vomiting — though use in pregnancy should only be under a doctor's supervision. We hold no effectiveness data in our records for folate in this product.
How safe is it?
Well-documented data
Vitamin B12 is generally very well tolerated with no established upper limit — excess amounts are simply removed in your urine. It's considered safe during pregnancy and breastfeeding at recommended amounts.
Vitamin B6 is safe at normal food and supplement amounts, but high doses over time can damage nerves (a condition called sensory neuropathy). The risk increases significantly with doses over 1,000 mg daily or very high cumulative doses, though neuropathy can occur at lower amounts as well.
Common side effects from vitamin B6 include headache, nausea, abdominal pain, heartburn, and loss of appetite. We have no pregnancy or breastfeeding safety data on file for folate in this context.
Meds to double-check
Moderate interaction found
Before starting DEVA Vegan B12, double-check with your pharmacist if you take seizure medications (phenobarbital or phenytoin), amiodarone for heart rhythm control, blood pressure medications, or metformin for diabetes. The vitamin B6 in this product may affect how seizure drugs work or increase sun sensitivity from amiodarone, and the B12 may interact with metformin's effect on absorption.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
DEVA Vegan B12 is a straightforward B-vitamin supplement useful if you're deficient in B12, B6, or folate, or if you're vegan (since B12 is mainly found in animal products). If you take metformin for diabetes, a seizure medication, amiodarone for heart rhythm, or any blood pressure medication, check with your pharmacist first — the interactions are generally manageable but need to be confirmed with your exact regimen.
Don't take high doses of this product without guidance, especially over long periods.

Vegan B12 by DEVA Drug Interactions
HelloPharmacist Interaction Report
DEVA Vegan B12 contains three active ingredients, two of which have documented interactions with medications.
Vitamin B6 is the ingredient with the most significant interaction concerns. It may increase photosensitivity caused by amiodarone (Cordarone), a heart rhythm medication — this is a moderate-severity interaction.
Additionally, high doses of vitamin B6 can reduce how your body handles two seizure medications: phenobarbital (Luminal) and phenytoin (Dilantin), potentially making them less effective. Vitamin B6 may also have additive blood pressure-lowering effects when combined with antihypertensive drugs (moderate severity).
At lower doses, it can speed up the breakdown of levodopa when taken alone, though not when carbidopa is added.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B12 has one documented interaction: metformin (Glucophage), used for type 2 diabetes, may lower your B12 levels over time because it can interfere with B12 absorption in your digestive system. This is a minor-severity interaction.
We could not check the third ingredient, folate, because we hold no interaction data for it.
Altogether, these interactions span 227 individual medications. Use the medication checker below to look up your exact prescriptions before starting this product.

For each ingredient in Vegan B12 with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Vitamin B6
Amiodarone (Cordarone)
Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Despite initial case reports suggesting that pyridoxine may have a protective effect against amiodarone-induced photosensitivity, preliminary clinical research suggests that pyridoxine may actually exacerbate this adverse effect.
Antihypertensive Drugs
Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure. Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine.
Phenobarbital (Luminal)
High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenobarbital, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenobarbital to avoid high doses of vitamin B6.
Phenytoin (Dilantin)
High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.
Preliminary clinical evidence suggests that vitamin B6 200 mg daily can reduce plasma levels of phenytoin, possibly by increasing metabolism. It is not known whether lower doses have any effect. Advise people taking phenytoin to avoid high doses of vitamin B6.
Levodopa
Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people.
Vitamin B12
Metformin (Glucophage)
Metformin, a common medication used to manage type 2 diabetes, has been associated with lower vitamin B12 levels in some individuals. Prolonged use of metformin can interfere with the absorption of B12 in the digestive system, potentially leading to a deficiency in this essential vitamin.
