HelloPharmacist Scorecard of Bugleweed Vanilla Flavor by TerraVita

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: bugleweed glycerite liquid extract. The extract is suspended in a liquid base with glycerin (a common solvent and preservative in liquid supplements) and vanilla flavor.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Bugleweed's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: mild overactive thyroid symptoms.
  • We looked for evidence on: Hyperthyroidism, Premenstrual syndrome (PMS), Thyroid function, Palpitations.
  • The closest evidence on file: Bugleweed is rated "Insufficient Reliable Evidence To Rate" for Hyperthyroidism (Natural Medicines).
  • Also on file: Bugleweed is rated "Insufficient Reliable Evidence To Rate" for Premenstrual syndrome (PMS).

The evidence for bugleweed isn't established in our data. It's used traditionally for overactive thyroid (hyperthyroidism), trouble sleeping (insomnia), and premenstrual syndrome, but the data we hold shows insufficient reliable evidence to rate how well it actually works for any of those purposes.

The evidence, ingredient by ingredient Bugleweed

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Bugleweed requires caution because it can affect how your thyroid works — use it only under a healthcare provider's supervision. The safety data advises against bugleweed during pregnancy; the facts note it's likely unsafe because of possible hormone effects.

It may also reduce prolactin and milk production, so the data advises against it while breastfeeding. No side effects were reported in the data we hold, but that doesn't mean they don't occur.

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 — Bugleweed.
  • The most serious interaction on file is rated Moderate.
  • For scale: 16 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, check whether you use any thyroid hormone medications (levothyroxine, liothyronine, desiccated thyroid, or combination thyroid products). Bugleweed may reduce how well they work — a moderate-level interaction.

If you're on thyroid medication, verify it with the search tool on this page.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and some safety-information gaps remain.

Bugleweed is a single-ingredient product that works on thyroid function. If you take thyroid hormone medication or have a thyroid condition, talk with your pharmacist or doctor first — this supplement isn't something to add on your own.

Even if you don't take thyroid drugs, its effects on hormones mean professional guidance matters.

Bugleweed Vanilla Flavor by TerraVita: Common Questions

Does Bugleweed Vanilla Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Bugleweed Vanilla Flavor has a known interaction with 16 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bugleweed Vanilla Flavor 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.
Can I take this if I'm pregnant or breastfeeding?
No — the safety data advises against it in pregnancy because of possible hormone effects. Bugleweed may also reduce milk production, so it's not recommended while breastfeeding. Talk to your doctor or pharmacist if you're pregnant, planning to become pregnant, or nursing.
What exactly is bugleweed extract used for?
Bugleweed is used traditionally to help with an overactive thyroid, trouble sleeping, and premenstrual syndrome. However, we don't have enough reliable evidence in our data to confirm how well it works for any of these uses.
Why does the label say to use it under a healthcare provider's guidance?
Because bugleweed can affect thyroid function. If you have a thyroid condition or take thyroid medication, using it without professional supervision could interfere with your treatment or your health.
What are the side effects?
No side effects were reported in the data we hold, but that's not a guarantee none occur. If you experience anything unusual while taking it, stop and talk to your pharmacist or doctor.
Is this the same as bugleweed tea or dried bugleweed?
This is a glycerite liquid extract, which is a concentrated form. The strength and how it's processed may differ from teas or dried herb preparations, so don't assume all bugleweed products work the same way.
