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.

WellBetX Berberine contains one active ingredient: berberine, a plant alkaloid (naturally occurring compound) extracted from plants like barberry and goldenseal. The capsule also contains inactive ingredients—microcrystalline cellulose, magnesium stearate, stearic acid, and silica—which are fillers and binders that help form and stabilize the capsule.

Does it work?

Moderate 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Blood sugar control and heart health support.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Hyperlipidemia, Hypertension, Coronary heart disease (CHD), Metabolic syndrome — and 4 related terms.
  • The strongest evidence on file: Berberine is rated "Possibly Effective" for Diabetes (Natural Medicines).
  • Also on file: Berberine is rated "Possibly Effective" for Hyperlipidemia, Hypertension.
  • Also on file: Berberine is rated "Insufficient Reliable Evidence To Rate" for Ventricular arrhythmias, Atrial fibrillation, Coronary heart disease (CHD), Congestive heart failure (CHF).

Berberine has possibly effective evidence for several conditions. Clinical research suggests it may help lower cholesterol (hyperlipidemia) and improve blood sugar control in people with type 2 diabetes.

It's also possibly effective for high blood pressure (hypertension) and polycystic ovary syndrome (PCOS), and preliminary evidence suggests it may help clear certain stomach infections caused by Helicobacter pylori bacteria. That said, the evidence for each condition is not yet conclusive—talk with your doctor about whether it fits your specific needs.

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 1 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.

Berberine is generally well tolerated in the short term but commonly causes digestive side effects: abdominal pain, bloating, constipation, diarrhea, gas, nausea, and vomiting. Some people also report dizziness, drowsiness, fatigue, or headaches.

Berberine must be avoided during pregnancy—it can cross the placenta and has been linked to harm in newborns. It must also be avoided while breastfeeding because it passes into breast milk.

If you're pregnant, planning to become pregnant, or nursing, do not use this product.

Each ingredient & the kinds of drugs it affects

For each ingredient in WellBetX Berberine 500 mg 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.

Berberine15 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.

WellBetX Berberine 500 mg by Natural Factors: Common Questions

Does WellBetX Berberine 500 mg by Natural Factors interact with any medications?
Yes. Based on its ingredients, WellBetX Berberine 500 mg has a known interaction with 1,160 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?
WellBetX Berberine 500 mg 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 or breastfeeding?
No. Berberine must be avoided during pregnancy—it can cross the placenta and has been linked to newborn harm. You must also avoid it while breastfeeding because it passes into breast milk. If you're planning to get pregnant or are nursing, do not use this product.
What side effects might I notice?
The most common are digestive: belly pain, bloating, constipation, diarrhea, gas, nausea, or vomiting. Some people also feel dizzy, drowsy, fatigued, or get a headache. These tend to happen when you start, so taking it with food may help.
Does berberine actually work for high blood pressure or high cholesterol?
The research supports it as possibly effective for both. Clinical studies show berberine may lower cholesterol levels and help control blood pressure, but the evidence isn't conclusive yet. It's best used alongside lifestyle changes, and you should work with your doctor on dosing and monitoring.
Why does berberine interact with so many drugs?
Berberine slows down the liver enzymes (CYP3A4, CYP2D6, and CYP2C9) that break down many common medications. When those drugs clear from your body more slowly, they build up and can cause side effects. That's why you need to check your exact medications before starting.
Is berberine safe to use long-term?
The safety data we hold shows berberine is generally tolerated in the short term, but we don't have strong evidence on long-term safety. Talk with your doctor or pharmacist about how long it's appropriate for you to take it.
What's the inactive stuff in this capsule?
The capsule itself is vegetarian. The fillers are microcrystalline cellulose, magnesium stearate, stearic acid, and silica—all standard binders and flow agents that help make the capsule stable.
