Delivery Methods & Dosage

Beta glucan’s benefits depend not only on its source and structure, but also on how it is delivered. Oral, intravenous, and topical formulations show distinct effects on immunity, metabolism, and tissue health, making delivery method and dosage central to its clinical use.

Clinical studies have used varying doses of yeast-derived (1,3)-(1,6) β-glucan, and practitioners should use the most pure beta glucan available due to its superior biological activity:

  • Children: 100 mg daily
  • General Adult Use: 250–500 mg daily for ongoing immune support
  • High-Stress Periods / Athletes: 250 mg daily
  • Acute Symptom Support: Up to 900 mg daily during illness
  • Vaccine Enhancement: Begin supplementation at least one week before vaccination and continue for 2–4 weeks after

Note: Take on an empty stomach for optimal absorption. β-glucan is recognized by immune cells in the gut-associated lymphoid tissue (Peyer's patches) and transported to immune organs.
