Organic Globe Artichoke Leaf
Also known as: Globe Artichoke, Artichoke, Artichoke Leaf Extract, Cynara scolymus
Overview
Globe Artichoke (*Cynara scolymus*) is a plant native to the Mediterranean region, widely recognized for its culinary uses and increasingly valued for its potential health benefits when consumed as a dietary supplement. The leaf extract, in particular, is rich in bioactive compounds like cynarin and caffeic acid, which are believed to contribute to its therapeutic effects. Primarily, artichoke leaf extract is used to support liver health, reduce cholesterol levels, and alleviate symptoms of irritable bowel syndrome (IBS). It is available in various forms, including capsules, tablets, and liquid extracts. Research on artichoke extract is growing, with several systematic reviews and meta-analyses suggesting its efficacy, although more high-quality trials are needed to confirm these findings. The available evidence generally supports its health benefits, but study quality and outcomes can vary.
Benefits
Globe Artichoke extract has shown promise in several key areas. A meta-analysis indicated that it can significantly reduce total cholesterol levels by approximately 17.6 mg/dL, suggesting a beneficial effect on lipid metabolism. Furthermore, artichoke supplementation may help reduce liver enzymes, such as AST and ALT, particularly in individuals with non-alcoholic fatty liver disease (NAFLD). Studies also suggest that it may improve symptoms of irritable bowel syndrome. These benefits make it particularly useful for individuals with hyperlipidemia or NAFLD. While the lipid-lowering effect is clinically significant, more research is needed to fully understand its impact on liver health and digestive function. Benefits may be observed within several weeks of consistent supplementation.
How it works
Artichoke leaf extract exerts its effects through several biological pathways. It inhibits cholesterol synthesis and enhances bile acid excretion, contributing to improved lipid metabolism. Additionally, its antioxidant properties help reduce oxidative stress, which may protect the liver from damage. The extract influences liver enzyme levels and may improve gut health, potentially alleviating symptoms of irritable bowel syndrome. Cynarin, a key compound in artichoke extract, is believed to play a significant role in these processes. However, the bioavailability of cynarin and other compounds is not fully understood and may vary depending on the formulation.
Side effects
Globe Artichoke extract is generally considered safe for most people when taken as directed. The most common side effects are gastrointestinal issues such as nausea and bloating, affecting more than 5% of users. Less common side effects (1-5%) include allergic reactions, although these are rare. Drug interactions are possible, particularly with cholesterol-lowering medications, so caution is advised. Artichoke extract is contraindicated during pregnancy and breastfeeding due to limited safety data. Individuals with allergies to plants in the Asteraceae family (e.g., ragweed, marigolds, daisies) should also exercise caution. It is important to start with a low dose to assess tolerance and to monitor for any adverse reactions. While rare, severe allergic reactions are possible and require immediate medical attention.
Dosage
The typical effective dosage of Globe Artichoke extract starts at 500 mg per day, with optimal dosages ranging from 500 mg to 1,000 mg per day. Doses above 1,000 mg are not commonly recommended due to a lack of established safety data. It is best taken with meals to minimize gastrointestinal side effects. The leaf extract form is most commonly used. The presence of food may influence bioavailability, so consistent timing with meals is advisable. No specific cofactors are required for its effectiveness. It's important to note that individual responses can vary, and consulting with a healthcare provider is recommended to determine the most appropriate dosage.
