Made from globe artichoke leaves, this polyphenol-rich extract modestly lowers total and "bad" cholesterol, with smaller drops in triglycerides. Liver markers improve in people with fatty liver; weaker signals exist for indigestion, blood pressure, and blood sugar. Effects are real but mild, largest when starting values are already high. Inexpensive and well-tolerated. (Full Review)

Protocol

Dose

600–1,800 mg/day

Cholesterol trials used the higher end (1,280–1,800 mg/day); digestive use often lower.

Form

Standardized leaf extract

Capsules or tablets; the leaf-extract form used in most lipid trials, distinct from inulin-rich whole-plant products.

Timing

Split, with meals

Divided into 2–3 daily doses with meals due to short metabolite half-life; supports digestion and reduces upset.

Time to effect

Lipids

6–12 weeks

Cholesterol changes emerge over consistent daily use, mirroring trial durations.

Digestion

Days to weeks

Digestive symptom relief can appear within days to a few weeks.

Immediate effect

None

There is no immediate, perceptible effect.

Benefits

High: Total and LDL cholesterol reduction

Medium: Triglyceride reduction; liver enzyme improvement in fatty liver

Low: Functional indigestion relief; blood pressure reduction in hypertensive adults; modest fasting blood sugar reduction

Speculative: Antioxidant and vascular protection; HDL-cholesterol and cardiovascular risk-ratio improvement

Contraindications

Bile duct obstruction or active gallstones

Known Asteraceae-family allergy

Pregnancy or breastfeeding

Key Interactions

Lipid-lowering drugs (statins such as atorvastatin, simvastatin)

Glucose-lowering drugs (metformin, sulfonylureas such as glipizide, insulin)

Blood-pressure-lowering drugs (ACE inhibitors such as lisinopril, ARBs, diuretics)

Anticoagulants and antiplatelets (warfarin, aspirin)

OTC antacids, acid reducers, and NSAIDs (ibuprofen, naproxen)

Other lipid-, glucose-, or pressure-lowering supplements (red yeast rice, bergamot, plant sterols, psyllium, berberine, garlic extract)

Risk & Side Effects

High: Mild transient digestive effects

Medium: Allergic reactions in Asteraceae-sensitive individuals

Low: Bile duct obstruction risk

Speculative: Additive hypoglycemic or hypotensive effects; theoretical liver strain at very high doses

Monitoring

Marker	Target	Why
LDL cholesterol	< 100 mg/dL (lower for high cardiovascular risk)	Primary target of artichoke's lipid effect
Total cholesterol	< 180 mg/dL	Consistently reduced by artichoke; broad lipid status
Triglycerides	< 100 mg/dL (conventional < 150 mg/dL)	Secondary lipid target reduced by artichoke
HDL cholesterol	> 50 mg/dL (women), > 40 mg/dL (men)	Detects whether the cholesterol ratio improves
ALT (alanine aminotransferase)	< 25 U/L (women), < 30 U/L (men); conventional up to ~40 U/L	Liver-cell stress marker improved in fatty liver
AST (aspartate aminotransferase)	< 25 U/L; conventional up to ~40 U/L	Complements ALT for liver status
Fasting glucose	70–85 mg/dL (conventional up to 99 mg/dL)	Captures artichoke's small glycemic effect

Cadence: Recheck relevant biomarkers at ~8–12 weeks after starting, then every 6–12 months during continued use; check blood pressure in the early weeks for those who are hypertensive or on blood-pressure medication.

Qualitative Assessment

Digestive comfort: reduced bloating, fullness, and post-meal discomfort
Bowel regularity: stool consistency and frequency
General energy and tolerability: absence of persistent gastrointestinal upset and a subjective sense of digestive ease
