Best 6 Artichoke Extract Supplements for Liver & Digestion (2026)

That heavy, overfull feeling after a rich meal, with bloating that lingers for hours, is one of the most common digestive complaints adults report. For many people, it comes down to how efficiently the body handles dietary fat.

Artichoke leaf extract has been studied for exactly this. Its caffeoylquinic acids, including cynarin, stimulate bile flow, and bile is what the body uses to emulsify and absorb fat. Randomized trials in adults with functional dyspepsia have linked artichoke leaf extract to less fullness and bloating than placebo.

The catch is that labels are hard to compare. Some list cynarin, others list total caffeoylquinic acids, and some advertise raw-leaf “equivalent” doses. This guide compares six extracts on standardization, real dose, testing, and cost per serving so you can choose with confidence.

1. Nutricost Artichoke Extract 600mg, 240 Vegetarian Capsules — Best Overall

Price: $16.95 (as of October 1, 2026)

At roughly $0.07 per capsule, Nutricost delivers a full 600 mg of cynarin-standardized extract for less than any other product in this guide.

Key Specs

• Active ingredient + form: Artichoke stem and leaf extract (Cynara scolymus L.), standardized to 5% cynarin
• Dose per serving: 600 mg (about 30 mg cynarin)
• Certifications: Non-GMO, gluten-free, vegetarian
• Third-party tested: Yes (ISO-accredited laboratories, per the brand)
• Servings per container: 240
• Price per serving: $0.07 (calculated manually, price as of October 1, 2026)

Key Benefits

Each capsule supplies about 30 mg of cynarin, the caffeoylquinic acid most associated with artichoke’s effect on bile secretion. The 600 mg dose sits at the low end of the roughly 600–1,920 mg daily range used in clinical trials.

The 240-capsule bottle covers eight months at one capsule daily, which makes consistent long-term use affordable.

Key Ingredients

• Artichoke extract (stem and leaf, 5% cynarin, 600 mg): Cynarin and related caffeoylquinic acids stimulate bile secretion, which helps the gut emulsify and absorb dietary fat.

Pros

• Lowest cost per serving in this guide at $0.07
• 600 mg per capsule, standardized to 5% cynarin
• Third-party tested by ISO-accredited laboratories
• 240 servings cover eight months of once-daily use

Cons

• Uses stem and leaf, while most clinical research used leaf-only extracts
• Some buyers find the capsules hard to swallow

Best Suited For

Adults who want a straightforward, single-ingredient artichoke extract they can take daily for months without a large upfront cost.

Usage Recommendations

Take 1 capsule daily with a meal that contains some fat, when bile release matters most. Give it 4–6 weeks of consistent use before judging results.

Customer Feedback

Buyers consistently describe Nutricost’s artichoke extract as solid quality that matches its label, and several long-term users say they have reordered for years. Value is a recurring theme, since the 240-count bottle feels inexpensive for how long it lasts. Many reviewers report subtle but steady digestive benefits after a few weeks, and some mention the capsules leave no taste or aftertaste.

Opinions split on swallowing, with a few people finding the capsules too large. A small number reported stomach cramps or a possible allergic reaction and stopped taking it. Others noticed no change at all, a reminder that results vary and that artichoke is not a substitute for medical care.

Summary: Nutricost earns Best Overall by pairing a full 600 mg cynarin-standardized dose and third-party testing with the lowest cost per serving here.

2. Zazzee Extra Strength Artichoke 20:1 Extract, 150 Vegan Capsules — Best Concentrated Extract

Price: $21.97 (as of October 1, 2026)

Zazzee uses a 20:1 leaf extract, so each 450 mg capsule is made from the equivalent of 9,000 mg of whole artichoke leaves.

Key Specs

• Active ingredient + form: Artichoke leaf 20:1 extract (Cynara scolymus), standardized to min. 5% caffeoylquinic acid
• Dose per serving: 450 mg (about 22.5 mg caffeoylquinic acid)
• Certifications: Vegan, non-GMO, gluten-free, GMP-certified facility, made in the USA
• Third-party tested: Yes (lab tested for purity and potency, per the label)
• Servings per container: 150
• Price per serving: $0.15 (calculated manually, price as of October 1, 2026)

Key Benefits

The extract is standardized to at least 5% caffeoylquinic acid, the compound family behind artichoke’s bile-stimulating effect. The formula is free of wheat, corn, soy, dairy, egg, fish, shellfish, and tree nuts.

Dose note: the “9,000 mg” figure describes raw-leaf equivalence, not the extract you swallow. At 450 mg of actual extract, one capsule delivers less than Nutricost (600 mg) and well below the 1,280–1,920 mg daily doses used in most clinical trials.

Key Ingredients

• Artichoke leaf extract (20:1, min. 5% caffeoylquinic acid, 450 mg): Caffeoylquinic acids stimulate bile secretion and show antioxidant activity in laboratory studies.

Pros

• Free of all major food allergens
• One small capsule a day, 150 days per bottle
• GMP-certified US manufacturing with stated third-party lab testing

Cons

• 450 mg of extract is the lowest per-serving dose in this guide (tied with NOW Foods)
• “9,000 mg” marketing can mislead shoppers comparing labels
• Several buyers reported stomach upset

Best Suited For

Vegan or allergy-conscious adults who want one small capsule a day and are comfortable starting at a modest dose.

Usage Recommendations

Take 1 capsule daily with food. If your stomach is sensitive, take it mid-meal rather than before eating.

Customer Feedback

Most reviewers rate Zazzee highly for quality, and value for money is one of its strongest themes, with buyers saying a five-month bottle feels fairly priced. Several people describe it as easy on digestion and say it helps keep things moving, including one reviewer who started it during recovery from surgery. Many say they plan to reorder.

Effectiveness reviews are mixed, and a meaningful share of buyers are unsure it did anything. Side-effect reports lean negative: a handful mention stomach upset, bloating, or nausea after a dose. Anyone with a sensitive stomach should take it with food and watch how they feel.

Summary: Zazzee earns Best Concentrated Extract for its 20:1 standardized leaf extract in a clean, allergen-free, once-daily capsule.

3. Jarrow Formulas Artichoke 500mg, 180 Veggie Capsules — Best Established Brand

Price: $32.94 (as of October 1, 2026)

With more than 3,200 Amazon ratings, Jarrow is the most widely reviewed artichoke extract in this guide, and its label states an exact 25 mg of caffeoylquinic acids per capsule.

Key Specs

• Active ingredient + form: Artichoke leaf extract (Cynara scolymus L.), standardized to 5% total caffeoylquinic acids
• Dose per serving: 500 mg (25 mg caffeoylquinic acids)
• Certifications: Non-GMO, gluten-free, vegan
• Third-party tested: Not stated on the label
• Servings per container: 180
• Price per serving: $0.18 (calculated manually, price as of October 1, 2026)

Key Benefits

Jarrow positions this formula around bile production and the absorption of fat-soluble nutrients, which matches artichoke’s best-documented mechanism. The label also carries a clear warning for people with gallbladder or bile duct blockages.

Dose note: at 500 mg, one capsule is below the 1,280–1,920 mg daily doses used in most clinical trials.

Key Ingredients

• Artichoke leaf extract (5% total caffeoylquinic acids, 500 mg): Caffeoylquinic acids increase bile output, which supports fat digestion and the uptake of vitamins A, D, E, and K.
• Maltodextrin (carrier, amount not disclosed): A starch-derived filler used in the capsule blend; the amount is small, but some buyers prefer to avoid it.

Pros

• Largest review base in this guide (3,268+ ratings)
• Label discloses exact caffeoylquinic acid content (25 mg)
• Six-month supply at one capsule daily
• Clear label warning for gallbladder and bile duct conditions

Cons

• Contains maltodextrin, which several reviewers dislike
• No third-party testing stated
• Some users find the capsule large

Best Suited For

Adults who prefer an established brand with a long review history and want a moderate daily dose for ongoing digestive support.

Usage Recommendations

Take 1 capsule per day with food, as the label directs. Pairing it with your largest meal of the day matches when bile demand is highest.

Customer Feedback

Reviewers frequently say Jarrow’s artichoke helps their digestion, especially after higher-fat meals, and some describe less stomach discomfort while eating. Quality ratings are strongly positive, and many buyers say they have reordered or would buy again. Several people take it alongside milk thistle and say it fits easily into their routine, and most find the capsules easy to swallow.

Cholesterol-related reports are mixed: some reviewers saw better lab numbers, while others saw no change or higher readings. The most common complaint is the maltodextrin, which some buyers say was not clear from product images. A few people also had stomach upset and stopped.

Summary: Jarrow earns Best Established Brand for its transparent 25 mg caffeoylquinic acid label, gallbladder safety warning, and the deepest review history here.

4. AMG Naturals Artichoke Extract Capsules, 60 Count — Best Additive-Free Formula

Price: $29.95 (as of October 1, 2026)

AMG Naturals lists only one other ingredient besides its artichoke leaf extract: the vegetable cellulose capsule itself.

Key Specs

• Active ingredient + form: Artichoke leaf extract (Cynara scolymus), standardized to 2.5% cynarin
• Dose per serving: 500 mg (about 12.5 mg cynarin, calculated from the label)
• Certifications: Vegan, gluten-free, non-GMO (per the brand)
• Third-party tested: Not stated
• Servings per container: 60
• Price per serving: $0.50 (calculated manually, price as of October 1, 2026)

Key Benefits

This is the cleanest label in our lineup, with no magnesium stearate, silicon dioxide, or flow agents. It is also free of lactose, fructose, soy, and yeast.

Dose note: 2.5% cynarin is half the standardization used by Nutricost, and the 500 mg dose is below the 1,280–1,920 mg daily amounts used in most clinical trials. The Amazon listing also advertises 7 mg cynarin per capsule, while the label’s 2.5% figure works out to about 12.5 mg.

Key Ingredients

• Artichoke leaf extract (2.5% cynarin, 500 mg): Cynarin is a caffeoylquinic acid that stimulates bile secretion, supporting the breakdown of dietary fat.

Pros

• Only one other ingredient: a vegetable cellulose capsule
• Free of gluten, lactose, soy, yeast, and common flow agents
• Strong 4.6/5 rating from 695+ buyers

Cons

• Most expensive per serving in this guide at $0.50
• Lower standardization (2.5% cynarin) than most competitors
• Cynarin content on the listing and label do not match

Best Suited For

People sensitive to common capsule additives who are willing to pay more for the simplest possible ingredient list.

Usage Recommendations

Take 1 capsule daily with a meal. A 60-count bottle lasts two months, so it also works as a trial before committing to a larger supply.

Customer Feedback

Buyers praise AMG Naturals for clean ingredients and capsules that are small, tasteless, and easy to swallow. Many reviewers say it supports their digestive wellness, and several trust its purity standards. Some say one bottle lasts long enough to justify the price. A number of buyers also describe benefits unrelated to digestion; these accounts are anecdotal and not supported by current artichoke research.

A noticeable minority felt it did nothing for them. One buyer received a bottle already past its expiration date, so check the date on arrival. Another reviewer reported a rice powder filler, which conflicts with the single excipient on the label.

Summary: AMG Naturals earns Best Additive-Free Formula because its label lists nothing beyond artichoke leaf extract and a plant cellulose capsule.

5. Nature’s Way Artichoke Standardized Extract, 60 Capsules — Best Artichoke + Milk Thistle Combo

Price: $11.19 (as of October 1, 2026)

Nature’s Way is the only formula here that pairs artichoke with milk thistle, and its 13% caffeoylquinic acid standardization is the highest in this guide.

Key Specs

• Active ingredient + form: Artichoke leaf extract standardized to 13% caffeoylquinic acids (calculated as chlorogenic acid), plus milk thistle seed extract
• Dose per serving (2 capsules): 600 mg artichoke extract (78 mg caffeoylquinic acids) + 300 mg milk thistle extract
• Certifications: Non-GMO Project Verified, gluten-free, vegan
• Third-party tested: Not stated
• Servings per container: 30 (2 capsules each)
• Price per serving: $0.37 (calculated manually, price as of October 1, 2026)

Key Benefits

At the label’s suggested intake of two servings daily, you get 1,200 mg of artichoke extract. That is close to the 1,280 mg daily dose used in a 12-week UK trial on cholesterol (Bundy et al., 2008).

Milk thistle adds silymarin, a flavonolignan complex studied for liver-cell protection. The label also carries the most complete warning in this guide, covering bile duct obstruction, gallstones, and ragweed-family allergies.

Key Ingredients

• Artichoke leaf extract (13% caffeoylquinic acids, 600 mg per serving): A high concentration of caffeoylquinic acids drives bile secretion for fat digestion.
• Milk thistle seed extract (300 mg per serving): Silymarin shows antioxidant and cell-membrane-stabilizing activity in liver cells in laboratory studies.

Pros

• Highest caffeoylquinic acid standardization here (13%, 78 mg per serving)
• Label-directed daily intake (1,200 mg) approaches clinical-trial doses
• Non-GMO Project Verified
• Clear warnings for bile duct obstruction, gallstones, and Asteraceae allergy

Cons

• At 4 capsules a day, one bottle lasts only 15 days (about $0.75 per day)
• Milk thistle adds a second herb to check against your medications
• Price shown reflects a 20% discount; list price is $13.99

Best Suited For

Adults who want a higher daily artichoke dose combined with milk thistle and don’t mind taking capsules twice a day.

Usage Recommendations

Take 2 capsules twice daily, preferably with food, as the label directs. Starting with one serving per day in the first week helps you gauge tolerance.

Customer Feedback

Many buyers say Nature’s Way keeps them regular and is easy on a sensitive stomach, and several describe it as their go-to for digestive comfort. Reviewers consistently call the capsules easy to swallow and simple to fit into a daily routine. Some report better cholesterol readings alongside diet changes, and the low bottle price and trusted brand come up often.

Some buyers noticed no change at all, and a few found the taste unpleasant. Because the label calls for four capsules a day, the bottle runs out quickly, so the real monthly cost is higher than the sticker price suggests.

Summary: Nature’s Way earns Best Artichoke + Milk Thistle Combo for its 13% standardization, complementary milk thistle, and near-clinical label dose.

6. NOW Foods Artichoke Extract 450mg, 90 Veg Capsules — Best GMP-Audited Budget Pick

Dose note: at 450 mg, this is tied for the lowest dose in our lineup and well below the 1,280–1,920 mg daily amounts used in most clinical trials.

Key Ingredients

• Artichoke leaf extract (min. 5% caffeoylquinic acid as cynarin, 450 mg): Caffeoylquinic acids stimulate bile flow and show antioxidant activity in laboratory studies.
• Ascorbyl palmitate (trace, antioxidant): A fat-soluble form of vitamin C added to help protect the extract from oxidation.

Pros

• NPA A-rated GMP manufacturing, audited by a third party

Best Suited For

Budget-minded adults who want a modest daily dose from a manufacturer with audited quality standards.

Usage Recommendations

Take 1 capsule daily with a meal. Store it in a cool, dry place, since a few buyers reported the capsule contents drying out over time.

Customer Feedback

Reviewers describe NOW’s artichoke extract as a reliable product they reorder often, and many say it offers excellent value for the price. The capsules are called easy to swallow with no aftertaste, and buyers like the vegetarian, additive-light formula. Several report feeling more comfortable in their stomach and more regular after consistent use.

Digestive reactions are mixed. Some users developed stomach aches, gas, or extra bloating and stopped taking it. One buyer said the capsule contents dried out within a few months, and another received capsules that felt hard and pellet-like.

Evidence-Based Ingredients

Artichoke leaf extract for digestive comfort

Artichoke has been used in European herbal medicine for centuries to ease indigestion. The strongest clinical support is an RCT: a six-week, double-blind, placebo-controlled trial in 247 adults with functional dyspepsia found artichoke leaf extract improved fullness, bloating, and related symptoms more than placebo (Holtmann et al., 2003).

The proposed mechanism is increased bile secretion, shown in a small human crossover study after a single dose (Kirchhoff et al., 1994).

Artichoke leaf extract for cholesterol

A 2018 meta-analysis of 9 RCTs with 702 participants found artichoke extract lowered total cholesterol by about 17.6 mg/dL and LDL by about 14.9 mg/dL on average (Sahebkar et al., 2018). These are modest changes compared with prescription medication, and an earlier Cochrane review judged the evidence too limited for firm conclusions (Wider et al., 2013).

A separate 2022 meta-analysis of 5 RCTs reported lower liver enzymes in adults with fatty liver, but trials were small and short.

Cynarin vs. chlorogenic acid

Cynarin (1,3-dicaffeoylquinic acid) and chlorogenic acid (5-caffeoylquinic acid) both belong to the caffeoylquinic acid family. That is why a “5% cynarin” label and a “5% caffeoylquinic acids” label are not directly interchangeable. Evidence for each marker on its own is mostly mechanistic, from laboratory and animal studies.

Milk thistle (silymarin)

Milk thistle has a long traditional use for liver complaints, and lab studies show silymarin has antioxidant and cell-protective activity. Human trials in liver disease have produced mixed results, and Cochrane reviews have not found a clear clinical benefit.

The ingredients in our top picks have traditional use and emerging-to-moderate clinical evidence for digestive comfort and bile flow. They are not treatments for liver disease, gallbladder disease, or high cholesterol and should not replace medical care.

What Are Artichoke Extract Supplements?

Artichoke extract supplements are concentrated preparations of globe artichoke (Cynara scolymus), almost always made from the leaves rather than the edible heart. The leaves hold the highest levels of caffeoylquinic acids, including cynarin and chlorogenic acid, plus flavonoids such as luteolin.

Manufacturers standardize these extracts to a set percentage of a marker compound so each capsule delivers a consistent amount. Most products are capsules providing 450–600 mg of extract.

They are used mainly to support bile flow, fat digestion, and comfort after meals, with secondary research on blood lipids and liver enzymes.

Common Signs You May Need Artichoke Extract Support

• Feeling uncomfortably full soon after starting a meal
• Bloating or gas that follows rich or fatty foods
• Mild nausea or heaviness after high-fat meals
• Occasional belching or upper-abdominal discomfort without a diagnosed cause
• Irregular digestion that improves when meals are lighter

Persistent pain, unexplained weight changes, yellowing of the skin, or vomiting need medical evaluation, not a supplement.

Key Ingredients to Look For

• Artichoke leaf extract: Leaf extracts were used in most clinical trials; look for a standardized leaf extract rather than whole-plant powder.
• Caffeoylquinic acids (including cynarin): These drive bile secretion. A label stating the exact milligrams per serving, like Jarrow’s 25 mg or Nature’s Way’s 78 mg, is easiest to compare.
• Luteolin and flavonoids: These contribute antioxidant activity; they are rarely standardized but are naturally present in quality leaf extracts.
• Milk thistle (optional): Paired with artichoke in some formulas for complementary liver support, though its clinical evidence is mixed.

How to Choose

• Standardization marker: Check whether the label lists cynarin or total caffeoylquinic acids, and convert the percentage to milligrams.
• Real extract dose: Compare milligrams of actual extract, not “raw leaf equivalent” figures. Trials mostly used 1,280–1,920 mg per day.
• Testing and manufacturing: Prefer brands that state third-party testing or audited GMP certification.
• Excipients: If you avoid maltodextrin, magnesium stearate, or silica, read the other-ingredients panel.
• Price per serving: Divide bottle price by servings, and account for products that need several capsules a day.

Who May Benefit

• Adults with occasional fullness or bloating after fatty meals
• People whose clinician has suggested natural support for mildly elevated cholesterol alongside diet changes
• Those looking for gentle digestive support as part of a Mediterranean-style eating pattern
• Adults who already tolerate artichoke as a food and want a consistent dose

Safety and Side Effects

Artichoke leaf extract is generally well tolerated in studies lasting up to 12 weeks. The most common side effects are mild gas, loose stools, and stomach upset.

Do not use it if you have a bile duct obstruction, and speak with a doctor first if you have gallstones, because increased bile flow can trigger symptoms. People allergic to the Asteraceae (daisy) family, including ragweed, chrysanthemums, and marigolds, may react to artichoke.

Safety data in pregnancy and breastfeeding are lacking, so avoid it during those times. Human data on drug interactions are limited. If you take cholesterol, diabetes, or blood-thinning medication, check with your prescriber, especially with formulas that add milk thistle.

What Results Can You Expect?

In the main dyspepsia trial, symptom improvements were measured over six weeks. Most people should allow 4–6 weeks of consistent daily use before judging digestive results.

Cholesterol studies ran 6–12 weeks, and average changes were modest, around 15 mg/dL for LDL. Some people notice no difference at all.

Lifestyle Tips

• Eat smaller, slower meals, and limit large high-fat meals that strain bile output
• Add soluble fiber from oats, legumes, and cooked artichoke hearts, which provide inulin
• Stay well hydrated to support regular digestion
• Walk for 10–15 minutes after meals to help gastric emptying
• Limit alcohol, which adds to the liver’s workload

FAQ

Final Thoughts

Nutricost Artichoke Extract 600mg is our top pick for most people. It combines a full 600 mg cynarin-standardized dose, third-party testing, and the lowest cost per serving in this guide.

If you want a higher daily dose with milk thistle, choose Nature’s Way Artichoke. If additives are your main concern, AMG Naturals Artichoke Extract has the simplest label, and Jarrow Formulas Artichoke 500mg suits those who prefer a long-established brand.

If you have gallstones, ongoing abdominal pain, or abnormal liver tests, see a doctor before trying any artichoke supplement.
