HelloPharmacist Scorecard of Artichoke Extract 450 mg by NOW

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 11, 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: artichoke extract at 450 mg per capsule. The extract comes from artichoke leaf and is used to support digestive and liver health.

The capsule also contains inactive ingredients — cellulose, silica, and magnesium stearate — which are standard binders and flow agents.

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: promote healthy digestive function and bile flow.
  • We looked for evidence on: Biliary disorders, Dyspepsia, Hyperlipidemia, Nonalcoholic fatty liver disease (NAFLD), cholestasis, fat malabsorption.
  • The strongest evidence on file: Artichoke is rated "Possibly Effective" for Dyspepsia (Natural Medicines).
  • Also on file: Artichoke is rated "Possibly Effective" for Hyperlipidemia.
  • Also on file: Artichoke is rated "Insufficient Reliable Evidence To Rate" for Biliary disorders, Nonalcoholic fatty liver disease (NAFLD).

Artichoke extract is possibly effective for high cholesterol (hyperlipidemia) and indigestion (dyspepsia), based on small clinical studies. For nonalcoholic fatty liver disease, the evidence isn't established enough in our data to rate it.

The evidence, ingredient by ingredient Artichoke

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.

Artichoke extract is generally well tolerated when taken as a supplement short-term, though quality and dosing vary by product. The most common side effects are mild — abdominal pain, diarrhea, gas, increased hunger, and nausea.

However, people allergic to plants in the ragweed and daisy family (Asteraceae) may be at higher risk for allergic reactions, including rare cases of severe anaphylaxis. If you have a known allergy to artichokes or these plant families, avoid this product.

During pregnancy, not enough safety information exists, so artichoke extract in supplement form is best avoided. Safety during breastfeeding hasn't been established either, so it should be avoided as well.

Side effects, ingredient by ingredient Artichoke

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 — Artichoke.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 363 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.

Before starting this product, double-check with your pharmacist if you take blood pressure medications or diabetes medications — artichoke can affect both. Also let them know if you take any drugs metabolized by CYP2C19 or CYP2B6 enzymes, as artichoke may increase their levels in your blood.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Artichoke extract may help with high cholesterol and indigestion if you're looking for herbal support. If you take blood pressure medications, diabetes medications, or drugs broken down by your liver, check with your pharmacist first — artichoke can affect how these work.

Avoid it if you're pregnant or nursing, or if you're allergic to ragweed or related plants.

Artichoke Extract 450 mg by NOW: Common Questions

Does Artichoke Extract 450 mg by NOW interact with any medications?
Yes. Based on its ingredients, Artichoke Extract 450 mg has a known interaction with 363 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Artichoke Extract 450 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.
What is artichoke extract used for?
Artichoke extract is used to support digestive health and may help lower cholesterol and reduce indigestion. The research shows it's possibly effective for both of those purposes, though it's not a treatment or cure.
Can I take this if I'm pregnant or breastfeeding?
No, it's best to avoid it. Not enough safety information exists for pregnancy, and safety during breastfeeding hasn't been established. Talk with your doctor or pharmacist for personalized advice.
What side effects might I notice?
Most people tolerate it well. The common side effects are mild — abdominal pain, diarrhea, gas, nausea, or increased hunger. If you're allergic to ragweed or daisy-family plants, you're at higher risk for an allergic reaction.
Is this safe if I take blood pressure or diabetes medication?
You need to check with your pharmacist first. Artichoke can lower blood pressure and blood sugar on its own, so combined with those medications it could push levels too low. It's a real concern, not just a caution.
How much should I take?
This product contains 450 mg of artichoke extract per capsule. Follow the dosage on the label, and if you have questions about what's right for you, ask your pharmacist or doctor.
