Comparison Studies

Not all beta glucans are created equal. Studies comparing different types show striking differences in purity, structure, and immune activity. Understanding these distinctions helps practitioners and patients make evidence-based choices.

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.
