Health Benefits
Enhances respiratory health by alleviating symptoms of bronchitis and colds
This provides relief from congestion and improves breathing. - Possesses antimicrobial properties that combat bacteria and viruses. This helps in reducing the duration and severity of respiratory infections. - Supports immune function by stimulating the production of immune cells. This strengthens the body's defense mechanisms against pathogens. - Contains anti-inflammatory compounds that reduce inflammation in the respiratory tract. This can alleviate symptoms of conditions like asthma and bronchitis. - May improve overall lung function by enhancing oxygen uptake. This supports better respiratory health and endurance. - Exhibits antioxidant properties that protect respiratory tissues from oxidative damage. This supports long-term respiratory health. - Supports throat health by soothing irritation and reducing cough. This provides symptomatic relief during respiratory infections.
Origin & History

How It Works
Mechanism of Action
EPs 7630 contains proanthocyanidins and other phenolic compounds that stimulate macrophage activity and enhance interferon-beta production. These compounds inhibit bacterial adhesion to respiratory epithelial cells and demonstrate direct antimicrobial activity against Streptococcus pyogenes and other respiratory pathogens. The extract also modulates cytokine production, reducing inflammatory responses while supporting immune function.
Clinical Evidence
Multiple randomized controlled trials involving over 2,000 participants demonstrate EPs 7630's efficacy for acute bronchitis and common cold symptoms. Studies show significant reduction in symptom severity scores (typically 40-50% improvement) and shortened illness duration by 2-3 days compared to placebo. Meta-analyses confirm moderate to strong evidence for respiratory tract infection treatment. Most trials used standardized doses of 30-60mg daily for 7-10 days.
Safety & Interactions
EPs 7630 is generally well-tolerated with mild gastrointestinal side effects reported in 1-5% of users. No significant drug interactions have been documented in clinical studies. Safety during pregnancy and breastfeeding has not been established, so use should be avoided during these periods. Individuals with autoimmune conditions should consult healthcare providers before use due to immune-stimulating properties.
