Artichoke

What does the research say about Artichoke?

3 health outcomes synthesised

Artichoke has been researched for 3 health outcomes, with the strongest evidence supporting its ability to reduce low-density lipoprotein (LDL) cholesterol—a meta-analysis of 5 studies found a moderate reduction of about 14.9 mg/dL, typically at 600 mg daily over 6–8 weeks. Evidence for lowering triglycerides and total blood cholesterol is moderate, though studies have mostly involved clinical populations such as people with non-alcoholic fatty liver disease (NAFLD) or metabolic syndrome, limiting generalizability to healthy individuals.

Strongest evidence: The highest quality evidence supports artichoke for reducing LDL cholesterol (high evidence strength), based on 5 studies including a meta-analysis showing a moderate reduction (WMD: -14.9 mg/dL). Doses of 600 mg daily for 6–8 weeks were most common. For triglycerides (moderate evidence), 4 studies consistently found small beneficial effects at 600–1800 mg/day over 8–12 weeks in people with NAFLD or metabolic syndrome. For total blood cholesterol (moderate evidence), 3 studies reported moderate reductions, again at 600 mg daily for 6–8 weeks.

Mixed or weaker evidence: No outcomes with low or very low evidence strength were identified; the three syntheses all show beneficial effects, but the triglyceride and total cholesterol findings are based on smaller numbers of studies (4 and 3, respectively), warranting caution.

Effective dose patterns: A daily dose of 600 mg of artichoke extract appears consistently effective across both LDL and total cholesterol outcomes, while triglyceride reduction studies used a wider range (600–1800 mg/day).

Population insights: The vast majority of research was conducted in clinical populations—primarily people with non-alcoholic fatty liver disease (NAFLD) or bariatric surgery candidates. Effects on healthy individuals remain less certain.

Notable caveats: All three syntheses note a risk of publication bias (null results less likely to be published). Many studies had small sample sizes (50–100 participants) or failed to report the exact form or dose of artichoke used. Effect sizes were small to moderate, and larger, longer-term trials are needed to confirm clinical significance.

Frequently asked

  • What is Artichoke good for according to research?
    Research shows artichoke extract may help reduce LDL cholesterol (5 studies, high evidence), triglycerides (4 studies, moderate evidence), and total blood cholesterol (3 studies, moderate evidence). All studies reported beneficial effects, but most focused on people with NAFLD or metabolic syndrome.
  • What dose of Artichoke is typically used in studies?
    For LDL and total cholesterol reduction, studies most commonly used 600 mg of artichoke leaf extract daily. For triglyceride reduction, the dose range was 600–1800 mg/day. Effects were typically seen over 6–12 weeks.
  • Who benefits most from Artichoke?
    The strongest evidence comes from studies in people with non-alcoholic fatty liver disease (NAFLD) and bariatric surgery candidates. Whether healthy individuals experience the same benefits is less clear due to limited generalizability of the research.
  • Are there caveats or limitations in the research on Artichoke?
    Yes. The clinical literature may be affected by publication bias (null results less likely to be published), most studies had small sample sizes, and some did not report the exact form or dose of artichoke used. Effect sizes were small to moderate, and longer-term trials are needed to confirm clinical significance.
  • Does Artichoke help reduce LDL cholesterol?
    Yes, across 5 studies, all reported beneficial effects on LDL cholesterol, with a meta-analysis showing a moderate reduction of approximately 14.9 mg/dL. The evidence strength is high, but the clinical relevance of this reduction remains to be confirmed in larger trials.
  • Does Artichoke help reduce triglycerides?
    All 4 studies on triglycerides showed beneficial effects, though the effect size was predominantly small. The evidence strength is moderate, and effective doses ranged from 600 to 1800 mg/day over 8–12 weeks in people with NAFLD or metabolic syndrome.
