HelloPharmacist Scorecard of Vitamin B-6 300 mg by VitaCeutical 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
This product contains one active ingredient: vitamin B6 (pyridoxine) at 300 mg per tablet. Vitamin B6 is a water-soluble B vitamin your body uses to form red blood cells, support your immune system, and help your nervous system work properly.
The tablet also contains inactive ingredients — calcium phosphate, calcium stearate, cellulose, silica, and stearic acid — which are fillers and binders that hold the tablet together.
Does it work?
Strong evidence
Vitamin B6 is effective for treating sideroblastic anemia (a rare blood disorder where your bone marrow can't make healthy red blood cells properly) and for correcting a straightforward B6 deficiency. It's likely effective for lowering homocysteine (a compound that builds up when B6 is low), and it's possibly effective for pregnancy-related nausea and vomiting.
The evidence also shows it works for pyridoxine-dependent epilepsy, a rare genetic condition where the body needs extra B6 to prevent seizures.
How safe is it?
Well-documented data
At normal doses — under 100 mg daily — vitamin B6 is well tolerated and rarely causes problems. The most common side effects are mild and include abdominal pain, headache, heartburn, nausea, and loss of appetite.
High doses over time, especially 1,000 mg daily or more, can cause sensory neuropathy (nerve damage that causes numbness or tingling), though this can happen even at lower doses with prolonged use. If you're pregnant, vitamin B6 is likely safe, but if you're considering it for morning sickness, talk with your doctor first — it's sometimes used at recommended levels but only under clinical guidance.
For breastfeeding, the safety data shows it's likely safe at normal amounts.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your doctor or pharmacist if you're on blood pressure medication, the seizure drugs phenobarbital or phenytoin, the heart drug amiodarone, or levodopa for Parkinson's disease. No interactions are documented for the ingredients we could not verify separately, but this product's vitamin B6 content does affect these four medication types.
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.
Vitamin B-6 is a straightforward choice for correcting a B6 deficiency or treating sideroblastic anemia. If you take blood pressure medication, seizure drugs, amiodarone, or levodopa, you'll need to check with your doctor or pharmacist before starting — the 300 mg dose is on the higher side and interacts with these drugs.
Stick to under 100 mg daily to keep side effects minimal, and avoid very high long-term doses to protect your nerves.

Vitamin B-6 300 mg by VitaCeutical Labs Drug Interactions
HelloPharmacist Interaction Report
VitaCeutical Labs' Vitamin B-6 300 mg does interact with several medication types through its single active ingredient, vitamin B6.
The most serious interaction is with blood pressure medications (antihypertensive drugs), where vitamin B6 may add to their effect and lower your blood pressure further than intended — a Moderate severity concern.
Read the full breakdown — every affected drug type, severity by severity
Vitamin B6 also has Moderate interactions with the heart rhythm drug amiodarone (Cordarone), where it may worsen sun sensitivity, and with two seizure medications: phenobarbital (Luminal) and phenytoin (Dilantin). High doses of B6 may reduce how well these seizure drugs work by speeding up how your body breaks them down.
Additionally, vitamin B6 has a Minor interaction with levodopa, the Parkinson's medication — it can reduce the drug's effect if levodopa is taken alone, though not when it's combined with carbidopa (as in Sinemet).
Altogether, these interactions span 210 individual medications. Before you start this product, check your exact prescriptions with the search tool on this page — especially if you take blood pressure medication, amiodarone, seizure drugs, or levodopa.

For each ingredient in Vitamin B-6 300 mg with known interactions, here are the types of medications it 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.
