What is elderberry and how does it support immune health?

Elderberry (Sambucus nigra) is a fruit rich in anthocyanins and flavonoids. Clinical studies have examined elderberry extract for its potential to reduce the duration and severity of upper respiratory infections by supporting cytokine-mediated immune responses.

What dosage of elderberry has been studied in clinical trials?

Clinical trials have used elderberry extract at doses equivalent to 300–600 mg per day of standardized extract, or 15 mL of syrup containing 38% elderberry extract, taken multiple times daily for 3 to 5 days.

What are the potential side effects of elderberry?

Standardized elderberry extracts are generally well tolerated. Raw or unripe elderberries contain cyanogenic glycosides and must never be consumed unprocessed. Mild gastrointestinal effects may occur. Some experts advise caution in autoimmune conditions due to immune-stimulating properties.

About

Elderberry (Sambucus nigra) contains anthocyanins and polyphenols that activate immune cells and stimulate cytokine production. Its flavonoids may bind to and inhibit viral surface proteins. Meta-analysis of RCTs found elderberry supplementation substantially reduces upper respiratory symptom duration and severity.

How It Works

Anthocyanins and polyphenols activate immune cells and stimulate cytokine production; flavonoids bind to and may inhibit viral surface proteins, potentially reducing viral entry and replication.
