HelloPharmacist Scorecard of Coptis Chinensis Extract by BulkSupplements.com

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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 12, 2026

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: Coptis chinensis extract, also known as goldthread. It's a traditional botanical extract standardized to berberine, an alkaloid compound that gives the herb its pharmacological effects.

The rest is inactive ingredients (excipients) that help deliver the extract.

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 don't have effectiveness data on file for Coptis chinensis extract. That means the clinical evidence for what this product does isn't established in our records — not that it doesn't work, but that we can't speak to it from the facts we hold.

The evidence, ingredient by ingredient Goldthread

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.

Coptis chinensis extract is tolerated short-term by some adults, but human safety data are limited and product quality varies widely between manufacturers. It's rated likely unsafe during pregnancy and breastfeeding because berberine can harm the fetus and newborn, and passes into breast milk.

If you're pregnant, planning to become pregnant, or nursing, avoid this product and talk with your doctor or pharmacist about alternatives.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check

  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.

Coptis chinensis extract2 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.

Coptis Chinensis Extract by BulkSupplements.com: Common Questions

Does Coptis Chinensis Extract by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, Coptis Chinensis Extract 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?
Coptis Chinensis Extract 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 while pregnant or breastfeeding?
No. Coptis chinensis extract is rated likely unsafe during pregnancy because berberine can harm the fetus. It's also likely unsafe while breastfeeding because berberine passes into breast milk and may harm the infant. Talk with your doctor about safe alternatives if you're pregnant, planning pregnancy, or nursing.
What is berberine and why does it matter?
Berberine is the active alkaloid compound in goldthread extract. It's what gives the herb its medicinal effects, but it's also what causes the documented interactions with medications — specifically by slowing how your liver breaks down certain drugs.
How do I know if my medication is affected by this?
The extract mainly affects drugs metabolized by a liver enzyme called CYP3A4. That includes many common medications for cholesterol, blood pressure, heart rhythm, and immune suppression. Use the medication checker on this page or ask your pharmacist to confirm whether your specific drugs interact.
Is this product standardized or regulated?
The facts note that human safety data are limited and quality varies between products. That's a sign you should choose a reputable manufacturer and talk with your pharmacist about which brand to trust.
