Cynarin is a phenolic compound found mainly in artichoke leaves (Cynara scolymus). It is commonly included in supplements aimed at supporting digestion and liver function.

What are the potential benefits of cynarin?

Cynarin (often as part of artichoke extract) is associated with antioxidant activity, bile-stimulating effects, and potential support for liver enzyme balance. It may also support cholesterol and triglyceride management in some people.

How does cynarin support digestion?

Cynarin can stimulate bile production and flow, which helps the body digest fats. This may reduce indigestion symptoms such as bloating or post-meal discomfort.

What is a typical cynarin dosage?

Supplement dosages commonly fall around 8–32 mg of cynarin per day, depending on the product and standardization. Follow the label directions and consider medical advice if you have liver or gallbladder conditions.

Is cynarin safe, and who should avoid it?

Cynarin is generally used as part of artichoke leaf supplements, but it may not be suitable for people with bile duct obstruction or certain gallbladder problems. Those who are pregnant, breastfeeding, or taking medications should consult a clinician before use.

Cynarin

Moderate study situation·7/10

A higher score indicates better study conditions, but not necessarily effectiveness.

Phenolic compound from artichoke leaves with antioxidant, choleretic, and potential liver-protective effects.

Digestion & Gut Health Anti-inflammatory Antioxidant Liver Health Gallbladder Support Cholesterol Management

dose range

8–32 mg

Divided in 2–3 daily doses with meals.

Consumption

Take with meals to promote bile flow and reduce potential digestive discomfort. Usually as part of an artichoke leaf extract standardized to 2.5–5% cynarin.

Not fat-soluble.

Best time

Best taken with main meals (breakfast/lunch/dinner) for digestive benefits. Separate from bile acid sequestrants.

Description

Cynarin is a bioactive molecule found mainly in artichoke leaves (Cynara scolymus). It is known for its antioxidant, choleretic (bile-stimulating), and potential hepatoprotective properties, and often used in supplements targeting liver and digestive health.

benefits

Main effects with level of evidence

Moderate

Note on evidence

Most evidence comes from studies of artichoke extract, of which cynarin is a key active component, rather than isolated cynarin. Effects on liver enzymes, digestion, and cholesterol have supporting clinical trial data, but research on isolated cynarin in humans is limited.

Supports Liver Enzyme Balance

Moderate

Cynarin, via artichoke extract, may help lower elevated liver enzymes (ALT, AST) in non-alcoholic fatty liver disease (NAFLD) and other mild liver dysfunctions, suggesting support for normal liver function.

Cholesterol and Lipid Management

Moderate

Artichoke-derived cynarin may contribute to modest reductions in total cholesterol, LDL cholesterol, and triglycerides, attributed to inhibition of cholesterol synthesis and increased bile excretion.

Particularly relevant for: Those with mildly elevated cholesterol · General cardiovascular support

Digestive Aid and Bile Flow

Limited

Cynarin stimulates bile production, which can improve fat digestion and alleviate symptoms of indigestion such as bloating and discomfort.
