HelloPharmacist Scorecard of Berberine by Klaire Labs
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
Klaire Labs Berberine contains a single active ingredient: berberine, an alkaloid compound extracted from plants like barberry and goldenseal. The capsule also contains microcrystalline cellulose, stearic acid, and silicon dioxide as inactive ingredients that help form and stabilize the supplement.
Does it work?
Moderate evidence
The evidence we hold suggests berberine may be effective for several conditions. Clinical research indicates it's possibly effective for high cholesterol (hyperlipidemia), high blood pressure (hypertension), type 2 diabetes, polycystic ovary syndrome (PCOS), and H. pylori bacterial infection.
That said, 'possibly effective' means the research is promising but not yet conclusive — you should talk with your doctor about whether it's right for your specific situation and how it compares to other options.
How safe is it?
Well-documented data
Berberine is generally well tolerated when taken by mouth short-term, but digestive side effects are common: abdominal pain, bloating, constipation, diarrhea, gas, nausea, and vomiting. Some people also report dizziness, drowsiness, fatigue, or headache.
The safety data advises against using berberine during pregnancy — it may cross the placenta and has been linked to harm in newborns. It's also not safe while breastfeeding because it passes into breast milk.
If you're pregnant, planning to become pregnant, or nursing, do not use this product.
Meds to double-check
Major interaction found
Check your medications against this product if you take cyclosporine (a Major interaction that can raise its levels dangerously), blood thinners or antiplatelet drugs, high blood pressure medications, diabetes drugs, sedating medications, or any drug your liver metabolizes through CYP3A4, CYP2D6, or CYP2C9 pathways. Your pharmacist can help you identify which of your medications fall into these categories.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
Berberine may help with cholesterol, blood pressure, blood sugar, and a few other conditions, but it interacts with a large number of medications. Before you start, check your prescriptions and over-the-counter drugs against our database — especially if you take immunosuppressants, blood thinners, blood pressure drugs, or diabetes medications.
Pregnant people and anyone breastfeeding should avoid it. Talk to your pharmacist or doctor if you're unsure whether it's right for you.

Berberine by Klaire Labs Drug Interactions
HelloPharmacist Interaction Report
Berberine by Klaire Labs interacts with a significant number of medications, and the most serious concern is cyclosporine (an immunosuppressant).
Berberine can slow how your body clears cyclosporine, raising its levels in your blood to potentially toxic amounts — a Major severity interaction that requires careful monitoring or possibly a different supplement.
Read the full breakdown — every affected drug type, severity by severity
Berberine also has Moderate interactions with several other drug types. It may increase bleeding risk when combined with blood thinners or antiplatelet drugs (like aspirin or warfarin).
It can add to the blood-pressure-lowering effects of high blood pressure medications, which could cause your pressure to drop too far. It may boost levels of drugs your liver clears through three different metabolic pathways (CYP3A4, CYP2D6, and CYP2C9 substrates), potentially raising their side effects.
And it can lower blood sugar further if you're already taking diabetes medications, raising the risk of low blood sugar (hypoglycemia).
Berberine may also increase sedation if you're taking sedating medications (central nervous system depressants). Altogether, these interactions span 1,148 individual medications.
Before you start this supplement, use the medication checker below to run through your exact prescriptions and over-the-counter drugs — that's the only way to know if one of your medications is affected.

For each ingredient in Berberine 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.
Berberine
Cyclosporine (Neoral, Sandimmune)
Berberine can increase serum levels of cyclosporine.
Berberine can reduce metabolism and increase serum levels of cyclosporine. Berberine might inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine.
Anticoagulant/Antiplatelet Drugs
Theoretically, berberine might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
In vitro and in vivo research suggest that berberine can inhibit platelet aggregation. Theoretically, berberine might have additive effects when used with anticoagulant and antiplatelet drugs and increase the risk of bleeding.
Antidiabetes Drugs
Theoretically, berberine may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research shows that berberine may lower blood glucose levels. Theoretically, berberine might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.
Antihypertensive Drugs
Theoretically, berberine might have additive effects with antihypertensive drugs.
Animal research suggests that berberine can have hypotensive effects. Also, a clinical study suggests that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone.
Cns Depressants
Theoretically, berberine might increase the sedative effects of CNS depressants.
Animal research suggests that berberine may have sedative effects. Theoretically, use of berberine along with CNS depressants might produce additive therapeutic and adverse effects.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, berberine might increase serum levels of drugs metabolized by CYP2C9.
Preliminary clinical research shows that berberine can inhibit CYP2C9. Theoretically, taking berberine with drugs metabolized by CYP2C9 might increase drug levels and increase the risk of adverse effects.
Cytochrome P450 2D6 (Cyp2D6) Substrates
Theoretically, berberine might increase serum levels of drugs metabolized by CYP2D6.
In vitro research and preliminary clinical evidence show that berberine can inhibit CYP2D6. Theoretically, use of berberine with drugs metabolized by CYP2D6 might increase drug levels and increase the risk of adverse effects.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, berberine might increase serum levels of drugs metabolized by CYP3A4.
In vitro research and preliminary clinical research show that berberine moderately inhibits CYP3A4. Theoretically, use of berberine with drugs metabolized by CYP3A4 might increase drug levels and increase the risk of adverse effects.
Dextromethorphan (Robitussin Dm, Others)
Theoretically, berberine may increase serum levels of dextromethorphan.
Preliminary clinical research shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan. This may increase the effects and side effects of dextromethorphan.
Losartan (Cozaar)
Berberine might reduce the therapeutic effects of losartan by decreasing its conversion to its active form.
Preliminary clinical research suggests that berberine can inhibit cytochrome P450 2C9 (CYP2C9) activity and reduce metabolism of losartan.
Metformin (Glucophage)
Theoretically, berberine might increase the therapeutic and adverse effects of metformin.
In vitro and animal studies show that berberine can increase the systemic exposure and half-life of metformin, potentially increasing metformin's effects and side effects. This interaction seems to be most apparent when berberine is administered 2 hours prior to metformin. Taking berberine and metformin at the same time does not appear to increase systemic exposure to metformin.
Midazolam (Versed)
Berberine can reduce metabolism of midazolam, which might increase the risk of severe adverse effects.
Preliminary clinical research shows that berberine can inhibit cytochrome P450 3A4 (CYP3A4) activity and reduce metabolism of midazolam.
Pentobarbital (Nembutal)
Berberine might increase the sedative effect of pentobarbital.
Evidence from animal research shows that berberine can prolong pentobarbital-induced sleeping time. Theoretically, combining berberine and pentobarbital might increase the sedative effects of pentobarbital.
Tacrolimus (Prograf)
Berberine has been associated with increased blood levels of tacrolimus.
In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of the tacrolimus dose to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL.
Acetazolamide
Laboratory studies and initial clinical findings suggest that berberine has the potential to increase acetazolamide concentrations in the body. More research is needed to confirm this interaction.
