HelloPharmacist Scorecard of Artichoke 400 mg by Signature Supplements

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.

Artichoke 400 mg contains one active ingredient: artichoke leaf extract. This is a concentrated form of the artichoke plant's leaves, prepared to deliver the compound in a 400 mg dose per capsule.

The product also includes two inactive ingredients — cellulose and diatomaceous earth — which are common capsule fillers and binders that help hold the supplement together.

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: Improves digestion and supports liver function.
  • We looked for evidence on: Dyspepsia, Hyperlipidemia, Nonalcoholic fatty liver disease (NAFLD), Biliary disorders, Indigestion, Constipation — and 2 related terms.
  • 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 leaf extract is possibly effective for high cholesterol (hyperlipidemia) and indigestion (dyspepsia). The evidence for these uses is present but modest — the data we hold rates both as possibly effective rather than confirmed.

For nonalcoholic fatty liver disease, the evidence isn't established enough for us to rate it one way or the other.

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 used orally, though quality and dosing vary widely between products. The most common side effects are mild — abdominal pain, diarrhea, gas, hunger, and nausea.

Some people may have an allergic reaction, especially if you're sensitive to plants in the ragweed family (chrysanthemums, marigolds, daisies, and others). Rarely, severe allergic shock (anaphylaxis) has been reported in people sensitive to the inulin fiber in artichoke.

During pregnancy, there isn't enough safety data, so it's best avoided in supplement form. The same applies to breastfeeding — safety hasn't been established, so it's best to skip it while nursing.

Side effects, ingredient by ingredient Artichoke

Meds to double-check

Moderate interaction found
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.

Check with us before taking this if you use antihypertensive drugs (blood pressure medications), antidiabetes drugs (insulin or diabetes pills), or any medication metabolized by the liver enzymes CYP2C19 or CYP2B6. Your pharmacist can help you figure out if artichoke is safe alongside what you're already taking.

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 might help with cholesterol or indigestion if those are concerns for you. But if you take blood pressure or diabetes medication, or any drug your liver breaks down, talk to your pharmacist first — the interactions are real, even if they haven't caused problems in large studies yet.

Avoid it in pregnancy and while breastfeeding.

Artichoke 400 mg by Signature Supplements: Common Questions

Does Artichoke 400 mg by Signature Supplements interact with any medications?
Yes. Based on its ingredients, Artichoke 400 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 400 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. Not enough safety information exists for pregnancy, so it's best avoided in supplement form. The same goes for breastfeeding — safety hasn't been established. Talk to your doctor or midwife about whether artichoke is okay for your situation.
What are the side effects I should watch for?
Most side effects are mild: abdominal pain, diarrhea, gas, hunger, and nausea. Rarely, people sensitive to artichoke or inulin (a fiber it contains) can have an allergic reaction, including severe allergic shock. If you've ever reacted to ragweed, chrysanthemums, daisies, or related plants, you may be at higher risk.
Does artichoke actually lower cholesterol and help digestion?
The evidence shows it's possibly effective for both high cholesterol and indigestion, based on clinical studies. That means there's real data supporting it, but the evidence isn't ironclad — results tend to be modest rather than dramatic.
How much will this lower my blood pressure?
Clinical trials show artichoke can reduce systolic blood pressure by around 3 mmHg and diastolic by around 2 mmHg. That's a small drop on its own, so it matters most if you're already taking blood pressure medication — that's when the risk of going too low becomes a concern.
What are the inactive ingredients in this product?
The capsule contains cellulose and diatomaceous earth, which are common fillers and binders that help hold the supplement together.
