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: goldenthread powder. Goldenthread is a plant whose root is used in herbal medicine, and it contains a compound called berberine, which is responsible for its interactions with medications.

There are no inactive ingredients listed for this product.

Does it work?

Couldn't assess
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 Goldthread product and its label doesn't state a use — see Goldthread'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.

We hold no effectiveness data for goldenthread in our records. That means the evidence for what this product actually does—whether it works for any particular condition—isn't established in the information we have on file.

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.

Goldenthread is generally tolerated short-term by some adults, but human safety data are quite limited, and product quality varies between brands. The safety data advises against using it during pregnancy or while breastfeeding: berberine may harm a developing fetus or a nursing infant.

We don't have adverse-effect reports from trials on file.

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 — Goldthread.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 644 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 with your doctor or pharmacist before taking this if you use cyclosporine (an immunosuppressant) or any medication metabolized by the CYP3A4 enzyme system—a category that includes many common drugs. Berberine can raise levels of these medications in your blood.

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.

Goldenthread Root Powder carries significant drug-interaction risks—especially with cyclosporine and a broad range of medications your liver processes. If you take any prescription medications, you need to clear this with your doctor or pharmacist before starting.

Pregnant people and those breastfeeding should avoid it entirely.

Goldenthread, Powder2 drug types · 643 drugs

Cyclosporine (Neoral, Sandimmune)

Berberine, a constituent of goldthread, can reduce metabolism of cyclosporine and increase serum levels. It might inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

There's very preliminary evidence that berberine, a constituent of goldthread, might inhibit cytochrome P450 3A4 (CYP3A4) enzyme. So far, this interaction has not been reported in humans. However, watch for an increase in the levels of drugs metabolized by CYP3A4 in patients taking goldthread. Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), clarithromycin (Biaxin), indinavir (Crixivan), sildenafil (Viagra), triazolam (Halcion), and numerous others. Use goldthread cautiously or avoid in patients taking these drugs.

Yes. Based on its ingredients, Goldenthread Root Powder has a known interaction with 643 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Goldenthread Root 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 goldenthread if I'm pregnant or breastfeeding?
No. The safety data advises against goldenthread in pregnancy and while breastfeeding—berberine, its active compound, may harm a fetus or nursing infant. Talk with your doctor or pharmacist about safe alternatives.
What is goldenthread used for?
We don't have effectiveness data in our records for what goldenthread is intended to treat. Ask your healthcare provider or check the product label for its intended use.
Is goldenthread safe to take long-term?
Human safety data are limited. It may be tolerated short-term by some adults, but we don't have good evidence for long-term use. Talk with your doctor if you're considering taking it regularly.
Does quality vary between goldenthread products?
Yes—quality and consistency vary between brands. That's one reason to discuss this product with your pharmacist before starting, especially if you have medications to manage.
Why does goldenthread interact with so many drugs?
Goldenthread contains berberine, which can slow down a major enzyme (CYP3A4) in your liver that breaks down hundreds of medications. When that enzyme is inhibited, drugs build up in your system and may reach unsafe levels.
