From the Research

The recommended dosage for elderberry extract supplements is 300 mg taken twice a day, as evidenced by the most recent and highest quality study 1.

Key Considerations

  • The dosage may vary based on the form and purpose of the supplement, but 300 mg twice a day is a well-tolerated and effective dose.
  • Commercial syrups, lozenges, and other forms of elderberry supplements may have different dosing recommendations, but 300 mg twice a day is a general guideline.
  • Elderberry works by inhibiting viral replication and enhancing immune response through its anthocyanin content and antioxidant properties.

Important Safety Information

  • Pregnant women, those with autoimmune conditions, and people taking immunosuppressants should consult healthcare providers before using elderberry supplements.
  • Raw elderberries contain cyanogenic glycosides that can be toxic, so it's essential to use commercially prepared elderberry products.

Study Findings

  • The ELDERGUT trial 1 found that 300 mg of elderberry extract taken twice a day was well-tolerated and effective in modulating the gut microbiome.
  • Other studies, such as 2 and 3, have also investigated the efficacy and safety of elderberry supplements, but the most recent and highest quality study 1 provides the best evidence for dosing recommendations.

Dosage Summary

  • For adults, a typical dose is 300 mg of standardized elderberry extract taken twice a day.
  • For prevention, a daily dose of 150 mg may be sufficient, but more research is needed to confirm this.
  • Elderberry supplements are generally used for short-term periods of 3-5 days during illness rather than long-term daily use.
