Sambucus Black Elderberry Extract
Also known as: Black elderberry, European elder, Black elder, *Sambucus nigra*
Overview
Black elderberry (*Sambucus nigra*) is a flowering shrub native to Europe and North Africa, renowned for its berries and flowers used traditionally in herbal medicine. Rich in anthocyanins and flavonols, it exhibits strong antioxidant, antiviral, and anti-inflammatory properties. Commonly, black elderberry is utilized to alleviate symptoms of respiratory infections, particularly the common cold and influenza. The research landscape around this ingredient is moderate, with several clinical trials and meta-analyses investigating its efficacy in reducing upper respiratory symptoms. Despite variability in study results, many findings suggest that supplementation with black elderberry extract can lead to significant health benefits, especially during cold and flu seasons.
Benefits
Research indicates that black elderberry extract effectively reduces the duration and severity of upper respiratory symptoms associated with viral infections, such as influenza. Meta-analyses show a large effect size, with many participants experiencing symptom relief within a few days of initiation. Secondary benefits may include improved cardiovascular health and immune function due to its anti-inflammatory and antioxidant properties. While black elderberry is generally safe for healthy populations, individuals with autoimmune disorders or those immunocompromised are advised to consult a healthcare provider prior to supplementation.
How it works
Black elderberry’s antiviral effects are thought to inhibit the replication of viruses while simultaneously modulating the immune response through cytokine regulation. Key bioactive compounds, anthocyanins and flavonols, interact with biological pathways that enhance immune functioning. The variability of absorption and bioavailability of these compounds may depend on the preparation and individual consumption factors.
Side effects
Black elderberry is generally assessed as safe when consumed in appropriately prepared forms. Most common side effects are rare and may include mild gastrointestinal upset. Severe reactions, including allergic responses and, in rare cases, acute pancreatitis, have been reported. Individuals on immunosuppressive therapy should exercise caution due to potential interactions. Additionally, raw or unripe berries contain toxic components and should be avoided. Individuals with autoimmune conditions are strongly advised to consult with healthcare professionals before use.
Dosage
For respiratory benefits, a minimum effective dose of 175-600 mg of black elderberry extract is typically recommended, with an optimal range between 600-900 mg per day for those under stress. Timely consumption at the onset of symptoms enhances efficacy. Various forms such as capsules, syrups, and lozenges are available, though bioavailability may fluctuate according to preparation methods. There is no established maximum safe dose, but exceeding recommended guidelines should be approached with caution.
