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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 3 active ingredients. Berberine HCl is the main one, a plant alkaloid studied for blood sugar and cholesterol support.

Cinnamon (cassia) is included for its possible effects on blood sugar, and chromium is a mineral that may help with glucose control. The capsule also contains inactive ingredients: gelatin, vegetable magnesium stearate, and silica.

Does it work?

Strong evidence
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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Blood sugar support and metabolic health.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (Prediabetes), Dyslipidemia, Hyperlipidemia, Metabolic syndrome, Obesity — and 4 related terms.
  • The strongest evidence on file: Chromium is rated "Likely Effective" for Chromium deficiency (Natural Medicines).
  • Also on file: Chromium is rated "Possibly Effective" for Diabetes.
  • Also on file: Berberine is rated "Possibly Effective" for Diabetes, Hyperlipidemia.

Berberine is possibly effective for high cholesterol (hyperlipidemia), polycystic ovary syndrome (PCOS), blood sugar control (diabetes), H. pylori infection, and high blood pressure (hypertension). Chromium is likely effective for chromium deficiency and possibly effective for diabetes; however, the evidence for chromium in prediabetes and schizophrenia is rated possibly ineffective.

Cinnamon's evidence isn't established in the data we hold — it's rated insufficient to say whether it works for the conditions it's studied in.

The evidence, ingredient by ingredient Berberine Cassia Cinnamon Chromium

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Berberine is generally well tolerated in the short term but commonly causes digestive upset — abdominal pain, bloating, constipation, diarrhea, gas, nausea, or vomiting. It may also cause dizziness, drowsiness, fatigue, or headache.

Berberine must be avoided during pregnancy and while breastfeeding because it crosses the placenta and enters breast milk, and has been linked to newborn harm. Cinnamon in food amounts is likely safe during pregnancy and breastfeeding, but high-dose supplement amounts should be avoided due to limited data; at very high doses over time, its coumarin content may harm the liver.

Chromium from food or a prenatal vitamin is generally acceptable in pregnancy, but extra supplement doses should be avoided unless your doctor recommends it; during breastfeeding, there is limited safety data on higher doses. Chromium is generally well tolerated at typical doses but may cause GI irritation, headaches, insomnia, irritability, or mood changes; rare serious effects include kidney or liver damage.

Each ingredient & the kinds of drugs it affects

For each ingredient in Berberine 500 mg with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Berberine HCl15 drug types · 1,160 drugs

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.

Likelihood Probable Evidence A
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence A
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence B
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence C
Berberine HCl full monograph & interactions

Cinnamon2 drug types · 442 drugs

Antidiabetes Drugs

Theoretically, cassia cinnamon may have additive effects with antidiabetes drugs.
Cassia cinnamon may lower blood glucose levels, and have additive effects in patients treated with antidiabetic agents. Dose adjustments to diabetes medications might be necessary.

Likelihood Possible Evidence B
Hepatotoxic Drugs

Theoretically, large doses of cassia cinnamon might cause additive effects when used with hepatotoxic drugs.
There is some concern that ingesting large amounts of cassia cinnamon for an extended duration might cause hepatotoxicity in some people. Cassia cinnamon contains coumarin, which can cause hepatotoxicity in animal models. In humans, very high doses of coumarin from 50-7000 mg/day can result in hepatotoxicity that resolves when coumarin use is discontinued. Lower amounts might also cause liver problems in sensitive people, such as those with liver disease or those taking potentially hepatotoxic agents.

Likelihood Possible Evidence D
Cinnamon full monograph & interactions

Chromium5 drug types · 178 drugs

Antidiabetes Drugs

Theoretically, chromium may have additive effects with antidiabetic agents and increase the risk of hypoglycemia.
Some research shows that taking chromium might lower blood glucose levels, especially in patients with poorly controlled type 2 diabetes.

Likelihood Possible Evidence A
Insulin

Theoretically, concomitant use of chromium and insulin might increase the risk of hypoglycemia.
In clinical research, chromium has been shown to increase insulin sensitivity,

Likelihood Possible Evidence B
Levothyroxine (Synthroid, Others)

Chromium might bind levothyroxine in the intestinal tract and decrease levothyroxine absorption.
Clinical research in healthy volunteers shows that taking chromium picolinate 1000 mcg with levothyroxine 1 mg decreases serum levels of levothyroxine by 17% when compared to taking levothyroxine alone. Advise patients to take levothyroxine at least 30 minutes before or 3-4 hours after taking chromium.

Likelihood Probable Evidence B
Aspirin

Theoretically, aspirin might increase chromium absorption.
Animal research suggests that aspirin may increase chromium absorption and chromium levels in the blood.

Likelihood Possible Evidence D
Nonsteroidal Anti-Inflammatory Drugs (Nsaids)

NSAIDs might increase chromium levels in the body.
Drugs that are prostaglandin inhibitors, such as NSAIDs, seem to increase chromium absorption and retention.

Berberine 500 mg by Wonder Labs: Common Questions

Does Berberine 500 mg by Wonder Labs interact with any medications?
Yes. Based on its ingredients, Berberine 500 mg has a known interaction with 1,343 medications, including 1 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Berberine 500 mg contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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. Berberine, the main ingredient, is not safe during pregnancy or while breastfeeding — it crosses into the placenta and breast milk and has been linked to harm in newborns. The other ingredients (cinnamon and chromium) have limited safety data at supplement doses, so they should also be avoided unless your doctor advises otherwise.
What side effects might I get from berberine?
The most common are digestive: stomach pain, bloating, constipation, diarrhea, gas, nausea, or vomiting. You might also experience dizziness, drowsiness, fatigue, or headache. These are usually mild, but stop taking it if they're bothersome and talk to us or your doctor.
Will this help my blood sugar?
Berberine and chromium are both possibly effective for diabetes, which means there's reasonable evidence they may help, though results aren't guaranteed. Cinnamon's evidence isn't established in our data. If you have diabetes, talk to your doctor before starting — berberine can lower blood sugar and may increase your risk of going too low if you're already on diabetes medication.
How long does it take to work?
The facts we hold don't say how quickly these ingredients start working. That's a good question to ask your doctor or pharmacist based on what you're taking it for.
Is this safe to take long-term?
Berberine is generally well tolerated short-term but the facts note caution for long-term use. Cinnamon at high doses for a long time may harm the liver due to its coumarin content. Chromium at typical doses is usually fine, but high or long-term doses may pose risks. Talk to your pharmacist about how long you plan to take it.
