Reishi Polysaccharides: The Immunomodulatory Powerhouse from Ganoderma Lucidum
1. What are Reishi Polysaccharides?
Reishi polysaccharides are a class of bioactive compounds extracted from the fruiting body or mycelium of Ganoderma lucidum, a medicinal mushroom revered in traditional medicine for millennia. Comprising primarily β-glucans (β-1,3-glucans and β-1,6-glucans), these water-soluble polysaccharides account for 15–30% of reishi’s active components. Characterized by high molecular weight (10–100 kDa), they exhibit potent immunomodulatory, antioxidant, and anti-inflammatory properties. Our reishi polysaccharides are purified via dual extraction (hot water and ultrasonic-assisted methods), yielding a white to light brown powder with ≥95% β-glucan purity, validated by HPLC and NMR spectroscopy.

2.3 Global Supply Network
We distribute reishi polysaccharides to over 80 countries, providing GMP-certified raw materials to 跨国药企 (multinational pharmaceutical companies), dietary supplement brands, and cosmetic formulators. Our vertically integrated supply chain—from controlled mushroom cultivation to final product—ensures traceability and compliance with USP, EP, and FDA regulations.
3. Product Source
3.1 Botanical Origin & Sourcing
Ganoderma lucidum is sustainably cultivated on organic hardwood logs (oak, maple) in controlled environments in Yunnan and Jilin, China, and Oregon, USA. We source mushrooms from USDA Organic and EU-certified farms, where cultivation avoids synthetic pesticides and fertilizers. Fruiting bodies are harvested at 12–18 months of growth, when polysaccharide content peaks at 20–25% (dry weight).
3.2 Production Process
- Mushroom Pretreatment: Fresh reishi is freeze-dried at -50°C to preserve thermolabile polysaccharides, then milled into 80-mesh powder.
- Dual Extraction:
-
- Hot Water Extraction: 90°C for 3 hours to solubilize β-glucans, followed by centrifugation to remove insoluble matter.
-
- Ultrasonic-Assisted Refinement: 40 kHz ultrasonic waves enhance cell wall disruption, increasing extraction yield by 30% compared to conventional methods.
- Purification: The extract undergoes ethanol precipitation and DEAE-cellulose chromatography to remove proteins and small molecules, achieving ≥95% β-glucan purity.
- Drying: Spray-dried at ≤100°C to form a free-flowing powder (particle size: 50–100 μm), with optional micronization for improved dissolution in aqueous systems.
4. Health Benefits & Mechanisms
4.1 Immune System Activation
- Dectin-1 Receptor Agonism: β-1,3-glucans bind to Dectin-1 receptors on macrophages and dendritic cells, triggering NF-κB and MAPK signaling pathways. This increases production of pro-inflammatory cytokines (IL-6, TNF-α) by 50% and enhances phagocytic activity (Journal of Immunology, 2022).
- Adaptive Immunity Support: Promotes T-cell differentiation (Th1/Th2 balance) and antibody production, critical for combating viral and bacterial infections.
4.2 Antitumor & Chemotherapy Support
- Apoptosis Induction: Induces programmed cell death in tumor cells (e.g., lung, breast, colon cancer) by upregulating Bax/Bcl-2 ratio and caspase-3 activation, as demonstrated in preclinical studies (Cancer Letters, 2023).
- Treatment Adjuvant: Reduces chemotherapy-induced toxicity by protecting hematopoietic stem cells and improving quality of life in cancer patients (Integrative Cancer Therapies, 2021).
4.3 Oxidative Stress & Inflammation Regulation
- Antioxidant Defense: Scavenges hydroxyl radicals (IC50 = 25 μg/mL) and enhances SOD/GSH-Px enzyme activity, reducing oxidative damage in cardiovascular and neurodegenerative diseases.
- COX-2 Inhibition: Suppresses inflammatory mediators (PGE2, IL-1β) by 40%, providing relief for rheumatoid arthritis and inflammatory bowel disease.
4.4 Metabolic & Gut Health
- Gut Microbiota Modulation: Acts as a prebiotic, promoting Bifidobacterium and Lactobacillus growth, which improves intestinal barrier function and short-chain fatty acid production (Gut Microbes, 2023).
5. Usage Guidelines
5.1 Pharmaceutical & Nutraceutical Use
- Oral Dosage: 500–1500 mg/day (standardized to 95% β-glucans) for immune support; 2000–3000 mg/day for therapeutic applications (e.g., cancer adjuvant therapy).
- Formulations: Capsules, tablets, or functional food fortification (0.5–2% in beverages, soups). For intravenous use (under medical supervision), sterile-grade polysaccharides are available.
5.2 Cosmetic Applications
- Topical Use: 1–5% in creams, serums, and masks to enhance skin immunity, reduce redness, and improve moisture retention.
5.3 Storage
Store in airtight, light-resistant containers at 15–25°C. Shelf life: 24 months unopened; 12 months after opening (recommended refrigeration for aqueous solutions).
6. Precautions
- Allergic Reactions: Rare but possible; perform a skin test for mushroom allergies before topical use.
- Blood Thinning Interaction: May enhance anticoagulant effects; consult a physician if taking warfarin or aspirin.
- Pregnancy/Lactation: Limited clinical data; avoid high doses without medical advice.
