HelloPharmacist Scorecard of L-Methionine by Herbadiet

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients: vitamin B6 and L-methionine. Vitamin B6 is an essential nutrient involved in nerve function, immune health, and the metabolism of amino acids and other compounds.

L-methionine is an amino acid that your body uses to build proteins and produce other important molecules like glutathione, a powerful antioxidant.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: supports bone health, mood, and digestion.
  • We looked for evidence on: Osteoporosis, Depression, Premenstrual syndrome (PMS), bone density, emotional wellbeing.
  • The strongest evidence on file: Vitamin B6 is rated "Possibly Effective" for Premenstrual syndrome (PMS) (Natural Medicines).
  • Also on file: Vitamin B6 is rated "Possibly Ineffective" for Osteoporosis.
  • Also on file: Vitamin B6 is rated "Insufficient Reliable Evidence To Rate" for Depression, Postpartum depression.

Vitamin B6 is established as effective for sideroblastic anemia (a blood disorder) and vitamin B6 deficiency itself, and likely effective for elevated homocysteine levels. It's also possibly effective for pregnancy-induced nausea and vomiting.

For L-methionine, the data we hold shows possibly effective evidence only for neural tube birth defects during pregnancy. For its other listed uses — acetaminophen poisoning, hay fever, asthma, and colorectal cancer — the evidence isn't established well enough to rate.

The evidence, ingredient by ingredient Vitamin B6 Methionine

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • 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 mg daily. The most common side effects are abdominal pain, allergic reactions, headache, heartburn, nausea, and vomiting.

At high doses over time — especially 1,000 mg daily or more — it can cause sensory nerve damage (neuropathy). L-methionine is well tolerated at food amounts.

Common side effects from supplements include dizziness, drowsiness, low blood pressure, and vomiting. High-dose L-methionine may raise homocysteine levels, a risk factor for vascular disease.

Both ingredients are likely safe in pregnancy; however, the safety data advises caution with high-dose vitamin B6 in pregnancy, and supplement doses of L-methionine during pregnancy have not been proven safe — talk with your doctor about dosing. Vitamin B6 is likely safe while breastfeeding; L-methionine's safety during breastfeeding hasn't been well studied.

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 2 matched ingredients 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 product, ask your pharmacist or doctor whether you use any antihypertensive drugs, amiodarone, phenobarbital, phenytoin, or levodopa without carbidopa. Vitamin B6 in this product may alter how these medications perform.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help with vitamin B6 deficiency or certain forms of anemia, though L-methionine's benefits are less clear from the evidence we hold. If you take blood pressure medications, amiodarone, seizure drugs, or levodopa without carbidopa, check with your doctor or pharmacist before adding this supplement — the vitamin B6 content could affect how your medications work.

A pharmacist can review your exact regimen and help you decide whether it's right for you.

Each ingredient & the kinds of drugs it affects

For each ingredient in L-Methionine 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.

L-Methionine by Herbadiet: Common Questions

Does L-Methionine by Herbadiet interact with any medications?
Yes. Based on its ingredients, L-Methionine 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?
L-Methionine contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this safe to take while I'm pregnant?
Vitamin B6 is likely safe in pregnancy, but high doses warrant caution — use only under a doctor's guidance. L-methionine is likely safe in pregnancy, though supplement doses haven't been proven safe, so talk with your doctor about the right amount for you.
Can high doses of this product cause nerve damage?
Yes. Vitamin B6 at doses exceeding 1,000 mg daily or very high total doses can cause sensory neuropathy (nerve damage), though it can happen at lower doses too. This product's dose matters — check the label and your doctor's recommendation.
Will this help with my homocysteine levels?
Vitamin B6 is likely effective for elevated homocysteine. L-methionine's effect on homocysteine isn't rated in our data, and high-dose methionine may actually raise homocysteine — discuss your specific situation with your doctor or pharmacist.
What are these ingredients used for?
Vitamin B6 supports nerve function and helps your body process amino acids. L-methionine is an amino acid your body uses to build proteins and make antioxidants like glutathione. Together they support protein metabolism and overall nutrient status.
Is there anything in this capsule besides the two active ingredients?
The capsule itself is made of vegetable cellulose, which is a standard capsule material. There are no other added ingredients listed.
