Hawthorn 2% Flavonoids

Hawthorn extract standardized to 2% flavonoids contains oligomeric procyanidins and vitexin that enhance cardiac contractility and vasodilation. These bioactive compounds improve coronary blood flow and strengthen heart muscle function through positive inotropic effects.

Origin & History

Hawthorn is a shrub native to Europe, North America, and Asia, traditionally used in herbal medicine. The extract is standardized to 2% flavonoids, known for their health benefits.

Historical & Cultural Context

Hawthorn has been used in traditional European medicine for centuries, particularly for its cardiovascular benefits.

Health Benefits

- Supports cardiovascular health by improving circulation and heart function, reducing the risk of heart disease. - Rich in antioxidants, hawthorn helps neutralize free radicals, promoting overall cellular health. - Enhances blood vessel health by strengthening the walls, which can lower blood pressure. - May improve exercise performance by increasing blood flow and oxygen delivery to muscles. - Supports mental health by reducing anxiety and stress, promoting a sense of calm. - Aids in digestion by improving gut motility and reducing bloating. - Contains anti-inflammatory properties that can help alleviate symptoms of chronic inflammatory conditions.

How It Works

Hawthorn flavonoids including vitexin, quercetin, and oligomeric procyanidins inhibit phosphodiesterase enzymes, increasing cyclic AMP levels in cardiac muscle. This enhances calcium availability for myocardial contraction while simultaneously activating nitric oxide synthase for improved endothelial function. The flavonoids also inhibit angiotensin-converting enzyme (ACE), contributing to vasodilation and reduced peripheral resistance.

Scientific Research

Research supports hawthorn extract's benefits for heart health, particularly in improving circulation and reducing blood pressure. Additional studies are needed to confirm these effects.

Clinical Summary

Multiple randomized controlled trials involving over 2,600 participants with mild to moderate heart failure show hawthorn extract (standardized to 2% flavonoids) significantly improves exercise tolerance and reduces symptoms. A large 2008 study of 2,681 patients found 450mg twice daily improved New York Heart Association functional class scores by 0.4 points compared to placebo. Meta-analyses demonstrate consistent improvements in left ventricular ejection fraction of 3-5% and increased maximum workload during exercise testing. However, most studies are of moderate quality with 8-16 week durations.

Nutritional Profile

- High in flavonoids, a type of antioxidant.
- Contains vitamin C and dietary fiber.
- Low in calories and free from fat.

Preparation & Dosage

Take 160-900 mg of hawthorn extract daily. Consult a healthcare provider before use.

Garlic, CoQ10, Magnesium

Safety & Interactions

Hawthorn is generally well-tolerated with mild side effects including dizziness, nausea, and fatigue reported in less than 3% of users. It may potentiate cardiac glycosides like digoxin, requiring dosage adjustments and monitoring. Concurrent use with beta-blockers or ACE inhibitors may cause additive hypotensive effects. Pregnancy and breastfeeding safety data is insufficient, so use should be avoided during these periods.
