HelloPharmacist Scorecard of B-6 50 mg by Carlson

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: vitamin B6 (pyridoxine), at 50 mg per tablet. It also includes several inactive ingredients — dicalcium phosphate, microcrystalline cellulose, stearic acid, magnesium stearate, silicon dioxide, ethylcellulose, methylcellulose, croscarmellose sodium, and pharmaceutical glaze — which serve as fillers, binders, and capsule material.

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: promotes energy production and cardiovascular health.
  • We looked for evidence on: Cardiovascular disease (CVD), Hyperhomocysteinemia, Hypertension, Hypertriglyceridemia, Atherosclerosis, Premenstrual syndrome (PMS) — and 4 related terms.
  • The strongest evidence on file: Vitamin B6 is rated "Effective" for Vitamin B6 deficiency (Natural Medicines).
  • Also on file: Vitamin B6 is rated "Likely Effective" for Hyperhomocysteinemia.
  • Also on file: Vitamin B6 is rated "Possibly Effective" for Premenstrual syndrome (PMS).

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

The evidence is likely effective for lowering homocysteine (a blood marker linked to heart health), and possibly effective for pregnancy-related nausea and vomiting — though if you're pregnant, use it only under a doctor's guidance.

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 is well tolerated in doses under 100 mg daily, and this product's 50 mg dose falls into that range. The most common side effects at normal doses are mild — abdominal pain, headache, heartburn, nausea, or loss of appetite.

The main caution is with high doses over time: very large amounts (generally 1,000 mg or more daily, or 1,000 grams or more total over time) can cause nerve damage (sensory neuropathy). Pregnancy ratings are mixed — the data lists it as likely safe in some contexts but possibly unsafe in others, so talk with your doctor if you're pregnant or breastfeeding before taking it.

Side effects, ingredient by ingredient Vitamin B6

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.

Check with your pharmacist before starting if you take seizure medications (phenytoin or phenobarbital), blood pressure medications, amiodarone (a heart rhythm drug), or levodopa by itself. These interactions are moderate to minor severity, but the 50 mg dose in this product is below the threshold where some effects have been observed.

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 B-6 supplement is a straightforward, single-ingredient product suitable for correcting B6 deficiency or supporting certain conditions under medical supervision. If you take seizure medications, blood pressure drugs, amiodarone, or levodopa without carbidopa, check with your pharmacist first.

The 50 mg dose is generally well tolerated, but it's worth verifying your specific medications on this page.

Each ingredient & the kinds of drugs it affects

For each ingredient in B-6 50 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.

Is this B-6 product safe to take if I'm pregnant?

Will this help with my B-6 deficiency?

What is vitamin B6 used for in the body?
Vitamin B6 (pyridoxine) helps your body break down proteins, make red blood cells, and support brain development and function. It's also involved in immune response and regulating homocysteine, a marker linked to heart health.
Are there any fillers in this product?
Yes, this tablet contains several inactive ingredients including dicalcium phosphate and microcrystalline cellulose as fillers and binders. If you're sensitive to any of these, check the full inactive ingredient list.
Is 50 mg a high dose of B-6?
No — 50 mg is a standard supplement dose and well below the threshold (200+ mg) where drug interactions or nerve damage from high doses have been documented in the research.
