AHCC (Active Hexose Correlated Compound)
Grade B: Good EvidenceA proprietary extract from shiitake mushrooms shown to enhance immune function, particularly natural killer (NK) cell activity.
Overview
AHCC (Active Hexose Correlated Compound) is a standardized extract derived from cultured Lentinula edodes (shiitake) mycelia. It's rich in alpha-glucans with a low molecular weight (about 5,000 daltons), which may enhance absorption and bioavailability compared to other mushroom polysaccharides.
AHCC has been extensively studied for its immune-modulating properties, with over 30 clinical trials examining its effects on immune function, infection resistance, and as a complementary therapy in various conditions. It's particularly noted for enhancing natural killer (NK) cell activity, a key component of innate immunity against viruses and abnormal cells.
Active Compounds
- • Alpha-glucans (partial acetylation)
- • Beta-glucans
- • Amino acids
- • Minerals
Primary Uses
- • Immune system support
- • Persistent viral infections (especially HPV)
- • Complementary cancer support
- • Liver health (NAFLD, hepatitis)
- • Post-surgical recovery
How It Works
AHCC's mechanisms of action include:
**Immune Enhancement:** - Increases natural killer (NK) cell activity and cytotoxicity - Enhances macrophage and dendritic cell function - Modulates cytokine production (increases IFN-gamma, IL-12; regulates IL-6, TNF-alpha) - Improves T-cell proliferation and function
**Antiviral Activity:** - Supports viral clearance through enhanced cell-mediated immunity - Particularly studied for HPV, influenza, and hepatitis C - May prevent viral entry and replication through immune upregulation
**Hepatoprotective Effects:** - Reduces liver enzyme elevation - Decreases oxidative stress in liver tissue - May improve liver fibrosis markers - Supports liver regeneration
The low molecular weight of AHCC's alpha-glucans allows for easier absorption in the gut and may explain its systemic immune effects.
Evidence by Condition
Evidence for Human Papillomavirus (HPV)
Verdict:
Promising RCT data showing enhanced viral clearance
Overall Assessment:
1 of 1 study shows positive effects. Includes 1 RCT.
Evidence for Non-Alcoholic Fatty Liver Disease (NAFLD)
Verdict:
Preliminary cohort data suggesting liver enzyme improvement
Overall Assessment:
1 of 1 study shows positive effects. More RCTs needed.
