Beta Glucan is fully independent — we don’t sell products, run ads, or accept sponsorships. Our only focus is delivering reliable, science-backed insights.
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.
