Quick summary
Hawthorn Extract (Crataegus extract) is a botanical supplement categorized under cardiometabolic and circulation health. It has been studied in humans for potential cardiovascular benefits, but currently no established official intake recommendations or authorized EU health claims exist. Evidence on clinical effectiveness and safety remains preliminary and inconclusive.
What is it?
Hawthorn Extract is derived from plants of the Crataegus genus, commonly known as hawthorn. Traditionally, it has been used as a supplement aimed at supporting heart and circulatory system health. The extract contains various bioactive compounds thought to contribute to its effects.
How it may work in the body
Hawthorn Extract is proposed to support cardiovascular function through multiple pathways, although the precise mechanisms are not conclusively established in humans. Mechanistic and animal studies suggest it might influence heart muscle contraction, blood vessel dilation, and antioxidant activity, but human clinical data are insufficient to clearly define its physiological actions.
Common supplement forms
Information regarding specific common supplement forms of Hawthorn Extract was not provided in the available evidence. It is typically available as liquid extracts, capsules, tablets, or teas derived from hawthorn berries, leaves, or flowers, but no comparative data on forms are supplied here.
Typical dosage and how it is used
There is currently no official recommended daily intake for Hawthorn Extract. The dosages used in clinical studies vary, but detailed amounts were not provided in the supplied evidence. Without established dosing guidelines, consumers should exercise caution and consult healthcare professionals before use.

Potential benefits: what does the evidence say?
Cardiovascular and circulation health
Hawthorn Extract has been studied in human trials for potential supportive effects on heart and circulation. Early evidence suggests it may have some influence on cardiovascular function; however, consistent high-quality clinical evidence and systematic reviews supporting specific benefits are lacking.
Limitations of current studies include small sample sizes, variable dosages, short durations, and mixed outcome results. Therefore, the evidence remains insufficient to draw firm conclusions about efficacy.
Side effects and safety
The evidence provided does not specify common side effects, contraindications, or toxicity related to Hawthorn Extract. Likewise, safety data including special precautions for certain populations are lacking. Given the limited safety profile, caution is advised, especially for individuals with underlying health conditions.
Drug and supplement interactions
No documented drug or supplement interactions were included in the available evidence. However, as Hawthorn Extract is believed to potentially affect heart function and circulation, theoretical interactions with cardiovascular medications cannot be ruled out and warrant professional consultation.
Who should be careful?
Due to incomplete safety and interaction profiles, individuals who have medical conditions, are taking medications (especially those affecting the heart or blood pressure), or who are planning surgery should exercise caution and seek advice from healthcare providers before using Hawthorn Extract.
Pregnancy, breastfeeding and special populations
No specific information on safety or use during pregnancy or breastfeeding was provided. As with many supplements, pregnant and breastfeeding women, children, and individuals with chronic diseases should consult healthcare professionals before use.
Quality, standardization and what to look for
Quality standards and standardized extract formulations for Hawthorn Extract were not described in this evidence set. Consumers should look for products produced by reputable manufacturers that comply with established quality control practices like third-party testing. Due to variable phytochemical content, standardized extracts may offer more consistent dosing, but relevant data are not available here.
