What is Beta Glucan Reishi?
Beta Glucan Reishi is a polysaccharide derived from the fruiting bodies of Ganoderma lucidum, a fungus long revered in traditional EastAsian wellness practices. Its key bioactive components are beta-glucans featuring 1,3- and 1,6-glycosidic linkages; these are among the most extensively studied polysaccharides found in medicinal fungi.
In the body, beta-glucans are believed to interact with immune cell receptors - including those on macrophages, neutrophils, and natural killer (NK) cells - helping to modulate the body's natural immune response.
Undersun supplies bulk Reishi beta glucan, a fine brown powder extracted from Reishi fruiting bodies by water extraction, with a standard content of 40%; concentrations can also be customized according to customer requirements.

Key Advantages:
- Standardized β-glucan content
- 100% Water-soluble grade
- USDA Organic and EU Organic certified
- FDA / Halal / Kosher certified
- Non-GMO & Vegan-friendly

Beta Glucan Reishi Benefits
The following benefits are summarized from traditional use and published research on Reishi (Ganoderma lucidum) polysaccharides. They are provided for formulation and educational reference and are not intended to diagnose, treat, cure, or prevent any disease.
1. Improving macrobiotic health
Increasing SCFAs to support cholesterol levels and reduce inflammation If there is an imbalance in your gut's microbiome, reishi beta glucan can result in an overgrowth of harmful microbes. Balancing intestinal health by acting as a prebiotic and influencing the growth of different species of bacteria. Your body's overall health may be affected.
Immune cell maturation is supported better in the fight against infections, including respiratory and post-surgical infections, when the microbiome is healthy. Irritable bowel disease patients may also benefit from its ability to reduce inflammation.
2. Healthier Immune System
Because beta glucan reishi can help stimulate and improve the immune system, it is now better able to fight:
Pathogens, infections, viruses, parasites, and cell mutations may all benefit from this stimulation of macrophage production. Your body's large white blood cells, which fight pathogens and foreign cells.
Beta glucan reishi mushroom can also be used as a complementary treatment for immune-related conditions because they can improve immune health.
3. Regulation of Blood Sugar and Cholesterol by beta glucan reishi mushroom
It partially dissolves in water to slow down the digestion of carbohydrates and the movement of food through the intestine. You'll feel satisfied for longer if you do this.
The metabolic system may be supported and blood sugar may be maintained by this. Blood sugar absorption is lowered by the slowed digestion of food.
Additionally, due to its indigestibility, soluble fiber must traverse the entire digestive tract. Because of this, it is able to bind to the cholesterol in food and aid in its elimination from the body.
Beta Glucan Reishi Applications
1. Dietary Supplements
The largest market segment for standardized Reishi beta-glucan extracts is dietary supplements:
- Immune support formulas: Can be blended with Vitamin C, zinc, elderberry, or astragalus to create daily immune-support formulas.
- Adaptogen and stress-relief blends: Paired with ashwagandha or rhodiola in hard capsules or tablets to support stress management and physical vitality.
2. Functional Foods and Beverages
Due to their excellent water solubility, Reishi beta-glucans are suitable for:
- Mushroom coffee blends: Formulated into instant coffee or tea bags, masking bitterness while providing functional benefits.
- Dry beverage premixes and elixirs: Water-soluble grades designed for rapid dispersion without sedimentation.
- Nutritional protein bars: Used as a functional active ingredient in baked goods and nutritional snack formulations.
3. Cosmetics

- Hydrating masks: Utilizing high-purity liquid or water-soluble powder extracts for deep hydration and barrier repair.

Why Choose Our Reishi Beta-Glucan?
1. Accurate Testing Method
Many standard Reishi extracts on the market list only "Total Polysaccharides," a figure that may include starch or dextrin derived from the cultivation medium.
Our Reishi extract is tested using the internationally recognized K-YBGL enzymatic method, which clearly distinguishes and verifies the actual content of true β-(1,3)/(1,6)-glucans.
2. 100% Log-Grown Fruiting Body
We use 100% Reishi fruiting bodies cultivated on natural logs as raw material. We avoid low-cost mycelium fermentation products or bag-cultivated substrates containing significant starch residues, thereby ensuring the integrity of active structures and high bioavailability.
3. Formulation-Friendly
Excellent flowability: 80–120 mesh size and controlled moisture content (7%) make it highly suitable for blending, tableting, and capsule filling.
High thermal and pH stability: Suitable for sterilization processes and baking applications in various functional foods and beverages.

FAQ
Q: How does Reishi β-glucan differ from β-glucans derived from other sources (such as yeast or oats)?
A: The β-glucans in Reishi are primarily high-molecular-weight, branched β-(1,3)/(1,6)-D-glucans. Beyond providing fundamental immune support, they also possess Reishi's unique adaptogenic properties, aiding in stress management and cellular health.
Q: Do you provide samples for testing?
A: Yes. We can provide free 50g–100g laboratory samples to your R&D and procurement teams for analysis, solubility testing, or pilot-scale production.
Q: What are the minimum order quantity (MOQ) and lead time?
A: The MOQ for standard-specification raw materials is 1 kg (for pilot/R&D purposes), while the MOQ for standard bulk orders is 25 kg. Standard specifications are stocked in our US warehouse and can be shipped within 3–5 business days of order receipt.
