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.

True Food B6 is a single-ingredient supplement: vitamin B6 (also called pyridoxine). The tablet contains inactive ingredients including microcrystalline cellulose, calcium from Lithothamnion calcarea, stearic acid, hydroxypropyl cellulose, magnesium stearate, a coating, and silicon dioxide.

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: vitamin B6 plus food-based nutrients.
  • We looked for evidence on: Premenstrual syndrome (PMS), Pregnancy-induced nausea and vomiting, Gastroenteritis-associated nausea and vomiting, Motion sickness, Vitamin B6 deficiency, Carpal tunnel syndrome — 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 Pregnancy-induced nausea and vomiting, Premenstrual syndrome (PMS).

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

The evidence shows it's likely effective for high homocysteine levels (hyperhomocysteinemia) and possibly effective for pregnancy-related nausea and vomiting — though if you're pregnant, use it only under a doctor's care.

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 generally well tolerated at doses below 100 mg daily. The most common side effects at standard doses are mild — abdominal pain, headache, heartburn, nausea, and loss of appetite.

High doses over time, especially 1,000 mg or more daily, can cause nerve damage (sensory neuropathy), which may develop even at lower cumulative doses. The safety notes advise against high doses unless a clinician recommends them.

There is no pregnancy or breastfeeding safety data on file for this ingredient; talk with your doctor or pharmacist if you're pregnant or nursing and considering this supplement.

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 your medications if you take seizure drugs like phenytoin or phenobarbital, blood pressure medications, amiodarone, or levodopa (especially without carbidopa). All of these have moderate-to-minor interactions with vitamin B6.

Formula

TRUE FOOD(R) B6 also contains B vitamins, betaglucans, glutathione, choline, inositol, amino acids and other phytonutrients naturally found in fermented food cultures of Saccharomyces cerevisiae (food yeast).

vitamin B6 plus a full spectrum of food-based nutrients

Vitamin B6 and magnesium are added to a completed fermentation of the culture Saccharomyces cerevisiae to form a homogenous mixture for better absorption in the gut and optimum bioavailability of all nutrients.

General Statements

Saccharomyces cerevisiae is grown in a non GM soya-based medium. The yeast cell walls are gently pre-digested and broken down with enzymes from pineapple and papaya fruit to release the nutrients within each cell. Yeasts take in nutrients rather than consuming them so are valued food sources for nutrients.

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.

True Food B6 by Higher Nature: Common Questions

Does True Food B6 by Higher Nature interact with any medications?
Yes. Based on its ingredients, True Food B6 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?
True Food B6 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 vitamin B6 safe if I take blood pressure medication?
Vitamin B6 may lower blood pressure on its own, so combining it with antihypertensive drugs could cause an additive effect — meaning your blood pressure might drop more than intended. This is a moderate-severity interaction. Check your specific medication and dose with your pharmacist or doctor before starting.
Can I take this if I take a seizure medication?
If you take phenytoin (Dilantin) or phenobarbital (Luminal), high doses of vitamin B6 may reduce how well they work by speeding up your body's metabolism of the drug. It's not clear whether the dose in this product causes that problem, so talk to your doctor or pharmacist first.
What are the side effects of high-dose vitamin B6?
At high doses — especially 1,000 mg daily or more, or cumulative doses of 1,000 grams or higher — vitamin B6 can cause sensory neuropathy, a type of nerve damage affecting sensation in your hands and feet. Lower doses can occasionally cause this too. At normal supplemental doses, headache, nausea, and abdominal pain are the most common side effects.
Will this help with morning sickness?
Vitamin B6 is possibly effective for pregnancy-related nausea and vomiting. However, it should only be used during pregnancy under a doctor's guidance, even though it's often recommended at standard doses for morning sickness.
Can I take this with levodopa?
If you take levodopa alone (without carbidopa), vitamin B6 may reduce how well it works. However, if you're taking Sinemet (levodopa plus carbidopa), this interaction doesn't occur. Clarify which form you take with your doctor or pharmacist.
