HelloPharmacist Scorecard of Vitamin B-6 50 Milligrams by NutraBio

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 supplement contains one active ingredient: vitamin B6 (pyridoxine) at 50 milligrams per capsule. Vitamin B6 is an essential B vitamin your body uses for nerve function, red blood cell formation, and how you process proteins and amino acids.

The capsule itself is made from vegetable material and rice flour (an inactive filler).

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

This product doesn't appear to be marketed for a specific use, so we graded Vitamin B6's overall clinical evidence instead.

Strong

Strong clinical evidence supports Vitamin B6 for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Sideroblastic anemia — rated "Effective" (Natural Medicines).
  • On file: Vitamin B6 deficiency — rated "Effective" (Natural Medicines).
  • On file: Pyridoxine-dependent epilepsy — rated "Effective" (Natural Medicines).
  • On file: Hyperhomocysteinemia — rated "Likely Effective" (Natural Medicines).
  • On file: Antipsychotic-induced hyperprolactinemia — rated "Possibly Effective" (Natural Medicines).

Vitamin B6 is effective for treating sideroblastic anemia and vitamin B6 deficiency. It's likely effective for lowering homocysteine (a blood protein linked to heart disease) and possibly effective for pregnancy-induced nausea and vomiting.

It's also used for pyridoxine-dependent epilepsy, where it's been shown to be effective. For other uses, the evidence isn't established in the data we hold.

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 at doses under 100 milligrams daily. The most common side effects are mild—abdominal pain, headache, nausea, heartburn, loss of appetite, and drowsiness.

The main concern with long-term use is sensory nerve damage (neuropathy), which is rare but can happen with doses over 1,000 mg daily or very high cumulative doses; it can occasionally occur at lower doses as well. High doses over time can harm your nerves, so stick to recommended amounts unless a doctor advises otherwise.

For pregnancy, vitamin B6 is rated likely safe at normal doses and is often used for morning sickness—but only under a doctor's guidance. It's likely safe during breastfeeding at recommended levels.

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.

Before you take this, double-check if you're on blood pressure medications, amiodarone (a heart rhythm drug), phenobarbital or phenytoin (seizure medications), or levodopa for Parkinson's disease. All of these interact at moderate to minor severity with vitamin B6.

The bottom line

Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This is a straightforward B-vitamin supplement for supporting nerve health and treating B6 deficiency. If you take blood pressure medications, seizure drugs, or levodopa, talk to your pharmacist or doctor before starting—they'll help you determine if it's right for you and at what dose.

Stick to recommended amounts and don't take this on top of other B-complex supplements without checking first.

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 B-6 50 Milligrams by NutraBio: Common Questions

Does Vitamin B-6 50 Milligrams by NutraBio interact with any medications?
Yes. Based on its ingredients, Vitamin B-6 50 Milligrams 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 B-6 50 Milligrams 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 50 mg a safe dose?
Yes. Vitamin B6 is well tolerated at doses under 100 mg daily, and 50 mg is well within that range. The concern for nerve damage comes from much higher doses (over 1,000 mg daily) or very long-term high intake. At this dose from a single supplement, you're safe—just avoid stacking it with other B-complex products without checking with your pharmacist.
Can I take this for morning sickness during pregnancy?
Vitamin B6 is rated likely safe in pregnancy and is often used for morning sickness, but only under a doctor's guidance. Talk to your OB or midwife before starting any supplement, even one that's considered safe—they'll make sure it's right for your situation.
What is vitamin B6 actually for?
Your body uses B6 for nerve function, making red blood cells, and processing proteins and amino acids. It's essential for keeping your nervous system and immune system working well. This supplement is effective for treating B6 deficiency and certain conditions like sideroblastic anemia, and it may help lower homocysteine levels, which is linked to heart health.
Will this interact with my blood pressure medication?
Possibly, yes. Vitamin B6 may add to the blood-pressure-lowering effect of antihypertensive drugs, which could lower your pressure too much. Talk to your pharmacist or doctor before taking this if you're on any blood pressure medication—they can advise whether it's safe for you and if you need monitoring.
What are the side effects?
Most people tolerate it well at this dose. The most common side effects are mild: nausea, headache, stomach pain, heartburn, or drowsiness. Sensory nerve damage is rare and happens mainly at much higher doses taken long-term. If you notice tingling, numbness, or nerve pain, stop and talk to your pharmacist.
Is this safe while breastfeeding?
Yes, vitamin B6 is rated likely safe during breastfeeding at normal recommended levels. If you have questions about your specific situation, check with your doctor or pharmacist.
