Sambucus nigra (Elder) Extract
Also known as: Elderberry extract, Black elderberry, Sambucus, Elder berry
Elderberry extract from Sambucus nigra contains anthocyanins and other polyphenols with traditional use for immune and respiratory support. Modern research shows moderate evidence for reducing cold/flu duration and severity.
Primary uses
- Immune support
- Cold/flu symptom relief
- Respiratory health
- Antioxidant support
How it works
- Anthocyanins provide antioxidant activity
- May inhibit viral replication and reduce inflammatory response
- Stimulates cytokine production for innate immunity
- Supports respiratory mucosa health
Dosage
- Typical range
- 300–1,000 mg daily (equivalent to 3,200–8,000 mg fresh berries standardized to anthocyanins)
- Timing
- With meals for better absorption and tolerance
- With food
- Recommended with food
- Duration
- Safe for short-term use (acute illness) and preventive use during cold/flu season (up to 3 months). May taper once viral season passes.
- Special populations

Evidence notes
Good evidence from multiple RCTs showing elderberry reduces cold/flu duration and symptom severity when taken prophylactically or within 48 hours of symptom onset. Standardization to anthocyanins strengthens product quality.
Grade B: Some human trials support key claims; further confirmation needed.
