Full disclosure
Ingredient Transparency · database check

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 powder. It's a traditional herbal remedy that people have used for thyroid-related concerns, though the evidence for those uses isn't well established in our data.

Does it work?

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 assessable

This is a single-ingredient Bugleweed product and its label doesn't state a use — see Bugleweed's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for bugleweed isn't established in the data we hold. It's been studied for hyperthyroidism, insomnia, and premenstrual syndrome, but we don't have reliable evidence to rate how well it works for any of these.

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 should only be used under the guidance of a healthcare provider because it may affect thyroid function. The safety data advises against it during pregnancy.

Additionally, bugleweed may reduce prolactin (a hormone that supports milk production) and shouldn't be used while breastfeeding.

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.

If you take thyroid hormones like levothyroxine, synthetic T3, or combination thyroid replacements, double-check with your pharmacist before starting bugleweed. It may reduce how your body converts and uses these medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

If you're taking thyroid medication, talk to your pharmacist or doctor before adding bugleweed—it may interfere with how well your prescription works. Anyone with thyroid concerns should use it only under medical supervision.

Pregnant people and those breastfeeding should avoid it.

Bugleweed Powder by TerraVita Premium Collection: Common Questions

Does Bugleweed Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Bugleweed Powder 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 Powder 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?
No. The safety data advises against bugleweed during pregnancy because there isn't enough data on how it affects your developing baby and because of its possible effects on hormones.
Is it safe while breastfeeding?
No. Bugleweed may reduce prolactin, the hormone needed for milk production, so it shouldn't be used while breastfeeding.
Does bugleweed actually work for hyperthyroidism?
The evidence isn't established in the data we hold. While it's been studied for overactive thyroid, we don't have reliable evidence to say how well it works.
What exactly does bugleweed do in the body?
Bugleweed is thought to affect thyroid function—specifically, it may block the conversion of T4 (an inactive form of thyroid hormone) to T3 (the active form your body uses). That's why it can interfere with thyroid medications.
Why do I need a healthcare provider if I use this?
Because bugleweed can affect thyroid function, it needs medical supervision. Your doctor or pharmacist should monitor you to make sure it's safe for your situation and isn't interfering with any other medications or conditions you have.
