Artichoke Extract for Health & Longevity - Quick Reference Sheet

Artichoke Extract for Health & Longevity

Created on 09/20/2026 – Quick Reference based on Evidence Review created using AI4L / Opus 5 – Audit

Concentrated leaf preparation, used in Europe for indigestion. Blood fats fall modestly, most where starting levels are high; liver stress markers drop in people with fat build-up in the liver. Common complaints are excess gas, bloating and loose stools; main cautions are daisy-family allergy and gallstones. Effects can be confirmed or excluded on personal laboratory results within three months. (Full Review)

Protocol

Standard dose range
320–640 mg, 2–3×/day
Standardized dry leaf extract. Lipid trials used 1,280–1,920 mg/day; liver trials 600–2,700 mg/day.
Best time of day
With meals
Preferably the largest fat-containing meal. Split dosing is standard; every positive trial used two or three daily doses.
Standardisation to look for
25–35:1 extract ratio
A stated drug-to-extract ratio plus a declared caffeoylquinic acid content. Products lacking both cannot be dosed meaningfully.
Time to effect
Blood lipids
6–12 weeks
12 weeks is the shortest fair assessment window.
Liver enzymes
8 weeks
Movement seen in fatty liver and overweight groups.
Digestive symptoms
2–6 weeks
Relief reported in the indigestion trials.

Benefits

Contraindications
  • Imaging-confirmed bile duct obstruction (any degree)
  • Symptomatic gallstone disease, or silent stones awaiting gallbladder removal
  • Known allergy to Asteraceae (Compositae) plants
  • Decompensated cirrhosis (Child-Pugh Class B or C)
  • Pregnancy, any trimester, or breastfeeding
  • Children under 12 years
Key Interactions
  • Statins (atorvastatin, rosuvastatin, simvastatin): Caution
  • Antihypertensives (amlodipine, lisinopril, losartan, hydrochlorothiazide): Caution
  • CYP3A4, CYP2C19 and CYP2B6 substrates (ciclosporin, clopidogrel, bupropion): Monitor
  • Bile acid sequestrants (cholestyramine, colesevelam): Monitor
  • Ursodeoxycholic acid and other bile therapies: Caution
  • Over-the-counter proton pump inhibitors and antacids (omeprazole, calcium carbonate): Monitor
  • Over-the-counter non-steroidal anti-inflammatory drugs (ibuprofen, naproxen): Monitor
  • Lipid-lowering supplements (bergamot, red yeast rice, berberine, plant sterols): Caution
  • Blood-pressure-lowering supplements (garlic, beetroot nitrate, hibiscus, magnesium): Caution
  • Prebiotic fibers (inulin, fructo-oligosaccharides) and probiotics: Monitor
  • Milk thistle, choline and other liver-directed supplements: Monitor

Risk & Side Effects

  • High: Gastrointestinal symptoms
  • Medium: Allergic reactions in people sensitized to Asteraceae plants
  • Low: Biliary colic with gallstones or bile duct obstruction; over-lowering when added to lipid or blood pressure medication
  • Speculative: Cytochrome P450 drug interactions; reduced fetal growth

Monitoring

Marker Target Why
LDL cholesterol < 100 mg/dL; < 70 mg/dL with existing vascular disease Primary efficacy target; predicts effect size
ApoB < 80 mg/dL; < 60 mg/dL at high risk Counts atherogenic particles, which LDL alone can understate
Triglycerides < 100 mg/dL Second lipid outcome that moved in pooled trials
ALT < 25 U/L (men), < 20 U/L (women) Primary liver outcome; largest documented effect
AST < 25 U/L Confirms the ALT signal and flags non-liver muscle sources
GGT < 25 U/L (men), < 18 U/L (women) Most sensitive marker of biliary and oxidative stress
HbA1c 4.8–5.3% Checks whether the inconsistent glycemic signal applies individually
hs-CRP < 1.0 mg/L Background inflammation that confounds liver and lipid readings
Seated blood pressure < 120/80 mmHg Tracks the small, contested pressure effect
Abdominal ultrasound No established numeric target; track liver size and steatosis (liver fat) grade against the individual's own baseline Detects gallstones before starting and documents liver fat

Cadence: Baseline before the first dose; liver panel repeated at 8 weeks; lipid panel and blood pressure at 12 weeks; then every 6–12 months for as long as use continues.

Qualitative Assessment

  • Fullness, bloating and belching after fat-containing meals
  • Stool consistency and frequency, and any change in flatulence
  • Upper-abdominal discomfort, particularly any new right-sided pain after meals
  • Energy levels in the two hours following a large meal
  • Appetite changes, since increased hunger has been described with these preparations
  • Any itching, rash or lip or mouth tingling, which would point to daisy-family sensitization
