HelloPharmacist Scorecard of Vitamin B6 100 mg by Bronson

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.

From our pharmacy team — supplement deep dive

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.

Bronson Vitamin B6 100 mg contains one active ingredient: vitamin B6 (also called pyridoxine). The tablet also includes inactive ingredients — microcrystalline cellulose, dicalcium phosphate, stearic acid, magnesium stearate, and silicon dioxide — which are fillers and binders that help hold the tablet together.

Does it work?

Strong evidence
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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Supports heart health and nervous system function.
  • We looked for evidence on: Cardiovascular disease (CVD), Hyperhomocysteinemia, Premenstrual syndrome (PMS), Diabetic neuropathy, Isoniazid-induced neuropathy, Vincristine-induced neuropathy — and 4 related terms.
  • The strongest evidence on file: Vitamin B6 is rated "Likely Effective" for Hyperhomocysteinemia (Natural Medicines).
  • Also on file: Vitamin B6 is rated "Possibly Effective" for Premenstrual syndrome (PMS).
  • Also on file: Vitamin B6 is rated "Possibly Ineffective" for Carpal tunnel syndrome.

Vitamin B6 is effective for sideroblastic anemia (a blood disorder) and vitamin B6 deficiency itself. It's also effective for pyridoxine-dependent epilepsy, a rare genetic seizure disorder.

The evidence suggests it's likely effective for lowering homocysteine (a compound linked to heart health), and possibly effective for pregnancy-related nausea and vomiting — though if you're pregnant and considering it for morning sickness, your doctor should guide that decision.

The evidence, ingredient by ingredient Vitamin B6

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.

Vitamin B6 at doses under 100 mg daily is generally well tolerated; the most common side effects in trials were mild — abdominal pain, headache, heartburn, nausea, and loss of appetite. The real caution kicks in at high doses over time: prolonged use of very high doses can damage nerves (sensory neuropathy), a serious but rare effect.

Daily doses above 1,000 mg or lifetime totals of 1,000 grams or more carry the most risk, though nerve damage can happen at lower doses too. For pregnancy and breastfeeding, we don't have safety data on file, so talk with your doctor or pharmacist about whether this dose is right for you.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Vitamin B6.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: Parkinson's medications.
  • For scale: 210 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.

Before starting, check with your pharmacist if you take blood-pressure-lowering drugs, amiodarone (Cordarone), phenobarbital (Luminal), phenytoin (Dilantin), or levodopa — especially if it's used without carbidopa (check whether your formulation includes carbidopa, such as in Sinemet). Moderate-severity interactions are possible with all of these.

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.

This 100 mg dose is useful if you have sideroblastic anemia, vitamin B6 deficiency, or pyridoxine-dependent epilepsy, or if your doctor recommends it for high homocysteine or pregnancy nausea. Be cautious if you take blood-pressure medication, seizure drugs, amiodarone, or levodopa without carbidopa — check with your pharmacist first.

At this dose you're unlikely to hit the high-dose nerve-damage threshold, but don't pile on extra B6 from other supplements without asking.

Each ingredient & the kinds of drugs it affects

For each ingredient in Vitamin B6 100 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 B65 drug types · 210 drugs

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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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 B6 100 mg by Bronson: Common Questions

Does Vitamin B6 100 mg by Bronson interact with any medications?
Yes. Based on its ingredients, Vitamin B6 100 mg has a known interaction with 210 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Vitamin B6 100 mg 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.
Will this help with my morning sickness?
Vitamin B6 is possibly effective for pregnancy-related nausea and vomiting, but only take it under your doctor's guidance. Your doctor can advise on dose and safety for your pregnancy specifically.
Is 100 mg a high dose?
No — 100 mg is a standard supplement dose and is generally well tolerated. The serious nerve-damage risk comes with much higher daily doses (above 1,000 mg) or very long exposure. At 100 mg you're not in that range, but don't stack extra B6 from other sources without checking first.
What are the side effects?
At doses under 100 mg daily, side effects are uncommon and usually mild — abdominal pain, headache, heartburn, nausea, or loss of appetite. Serious side effects are rare at standard doses. High doses taken over long periods can harm your nerves, but that's not a concern at this level.
Can I take this with my seizure medication?
Only if your dose stays at or below 100 mg. High-dose vitamin B6 (200 mg and above) may reduce how well phenobarbital or phenytoin work. At 100 mg you're likely okay, but mention it to your pharmacist to be sure.
Is this the same as the B6 in my multivitamin?
Possibly — multivitamins usually contain much smaller amounts of B6. If you're already taking a multi, adding this 100 mg tablet will increase your total intake. Check the label on your other supplements and let your pharmacist know your total B6 from all sources.
Will this interact with my blood pressure medicine?
Vitamin B6 may add to the blood-pressure-lowering effect of your medication. This is listed as a moderate interaction, so check with your pharmacist before starting — they can monitor your blood pressure or adjust your routine as needed.
