Fermented Shiitake Mycelium AHCC Extract Powder is a premium immune support ingredient extracted from cultured Shiitake mycelium using a fermentation process. Also known as active hexose-related compound, AHCC extract or AHCC mushroom powder, this natural compound is widely recognized for its beneficial effects on immune regulation, stress response and cellular health.
AHCC differs from common mushroom extracts in that it is rich in low molecular weight alpha-glucans, a water-soluble polysaccharide that plays a key role in enhancing immune function. Unlike the beta-glucans commonly found in many other mushrooms, the alpha-glucans in AHCC are more easily absorbed by the body, making it a top choice for functional foods, supplements and overall health formulations.
With the growing global interest in natural immune boosters, especially among aging populations and health-conscious consumers, AHCC has become a key ingredient in immune support blends, detoxification regimens and energy-boosting supplements. Demand for AHCC is particularly strong in Japan, the United States and parts of Europe, where it is often used in preventive health and complementary treatment formulations.
Specializing in producing fermented AHCC extract powders with consistent quality and excellent dispersibility. Our products are manufactured to strict standards for alpha-glucan content and under strict quality systems, including ISO22000, HALAL, KOSHER, and FSSC22000 certifications. Unlike many generic AHCC powders, our material maintains stable bioactivity while offering OEM/ODM flexibility to meet your brand's unique formulation needs - whether you need capsules, blends, sachets, or functional food formats. Our in-house R&D team also supports custom ingredient ratios or synergistic formulations to pair AHCC with other mushroom or herbal active ingredients.
Our AHCC extract is standardized to ≥20% α-Glucan (HPLC tested), a functional level consistent with the clinical reference formula. Many commercially available products claim to contain "AHCC" but lack transparent testing or consistent levels of bioactivity.
We use a liquid fermentation process that contains no rice bran or corn starch residues, which are common in lower-priced AHCC products. This ensures higher purity, lower allergen risk, and improved formulation solubility.
Our proprietary enzymatic process maintains the molecular weight of α-Glucan within the ideal 5,000-50,000 Da range, enhancing its absorption into human cells.
We offer low-dust, fine-pored powders optimized for direct tableting, capsule filling, or blending into sachets and granules. Our in-house team supports turnkey OEM/ODM projects, including taste masking, synergistic herbal pairings, and small-batch pilot production.

While elderberry is generally safe, it may interact with immunosuppressants or diabetes medications. Always consult a healthcare provider before combining it with other treatments.
Elderberry extract contains anthocyanins as well as vitamins A and C, which are known to stimulate the immune system and fight inflammation. It works by supporting the body's natural defense mechanisms against pathogens.
Of course. Elderberry extract is rich in antioxidants that help protect the skin from environmental stressors and reduce signs of aging. It is commonly found in serums and moisturizers that target skin health.
While elderberry cannot completely prevent colds, taking it early can help reduce the severity and duration of cold symptoms. Its antiviral properties help fight cold viruses.
AHCC extract is widely used in dietary supplements (capsules, tablets, gummies), functional beverages (immunity boosters, mushroom coffee mixes), immune support formulas (often combined with beta-glucan, ganoderma or vitamin C), anti-aging formulas (for cell health and stress resistance), and oncology or complementary health products for chemotherapy recovery.
For powdered raw material, the dosage ranges from 200 mg to 1,000 mg per serving. For OEM capsules, the standard dosage is typically 500 mg per capsule, while for functional beverages, a daily dosage of 1 gram is recommended.
