Hawthorn Seed Extract
Also known as: Hawthorn Seed Extract, Crataegus Seed Extract, Hawthorn Extract, Crataegus Extract
Overview
Hawthorn seed extract is derived from the seeds of plants in the *Crataegus* genus, commonly known as hawthorn. It is primarily used as a cardiovascular health supplement due to its rich content of bioactive compounds like flavonoids and polyphenols. While research is more extensive on whole hawthorn extracts, hawthorn seed extract is believed to share similar antioxidant and cardiovascular protective properties. It is often considered for managing symptoms of heart failure and hypertension. Hawthorn extracts are available in various forms, including capsules and tablets, and are sourced directly from the seeds of the hawthorn plant. The quality of evidence is moderate, with ongoing research aimed at further elucidating the specific benefits and mechanisms of hawthorn seed extract.
Benefits
Hawthorn seed extract, similar to whole hawthorn extracts, may offer benefits for individuals with mild to moderate heart failure. Research on whole hawthorn extracts indicates improvements in symptoms such as dyspnea and fatigue, as well as enhanced exercise capacity. A meta-analysis involving 632 patients with chronic heart failure showed significant improvements in maximal workload when using hawthorn extracts. Additionally, hawthorn extracts possess antioxidant and lipid-lowering properties, potentially contributing to overall cardiovascular health. The benefits typically manifest over several weeks to months of consistent use. However, it is important to note that more research is needed to specifically confirm these benefits for hawthorn seed extract.
How it works
Hawthorn extracts are believed to exert their beneficial effects through several mechanisms. Primarily, they promote vasodilation, which helps to improve blood flow and reduce blood pressure. Additionally, they enhance cardiac contractility, improving the heart's ability to pump blood efficiently. The antioxidant properties of hawthorn extracts also play a role by reducing oxidative stress in the cardiovascular system. Flavonoids and polyphenols present in hawthorn interact with various molecular targets involved in cardiovascular health. These actions collectively contribute to improved heart function and overall cardiovascular well-being.
Side effects
Hawthorn seed extract is generally considered safe when used as directed, although specific data on seed extracts is limited. Common side effects associated with whole hawthorn extracts include nausea, dizziness, and gastrointestinal complaints. Due to limited research, uncommon and rare side effects are not well-documented for seed extracts specifically. Potential drug interactions exist, particularly with cardiovascular medications, so caution is advised. It is contraindicated in individuals with severe heart failure or when combined with certain medications without medical supervision. Pregnant or breastfeeding women should consult healthcare providers before use. Monitoring for side effects and potential interactions is crucial when using hawthorn seed extract.
Dosage
Due to limited research on hawthorn seed extract specifically, the minimum effective dose and maximum safe dose are not well-established. Typically, whole hawthorn extracts are used at doses ranging from 500 to 1,000 mg per day. Consistent daily dosing is recommended for optimal results. Hawthorn seed extract is commonly available in capsule or tablet form. Bioavailability may be influenced by the presence of other nutrients or medications. It is advisable to consult with a healthcare provider to determine the appropriate dosage and ensure safety, especially when combining with other medications or supplements.
FAQs
