Chaga Mushroom (Inonotus obliquus)
A parasitic fungus with one of the highest antioxidant capacities of any natural substance, traditionally used in Siberian and Nordic folk medicine for immune support and increasingly recognised for neuroprotective potential.

What is Chaga Mushroom (Inonotus obliquus)?
Chaga (Inonotus obliquus) is a parasitic fungus that grows primarily on birch trees in cold climates across Siberia, Northern Europe, Canada, and the northern United States. Unlike typical mushrooms, chaga forms a hard, dark conk (sclerotium) that protrudes from the tree trunk and accumulates an extraordinarily dense concentration of bioactive compounds including betulinic acid (derived from the birch host), melanin, polysaccharides (beta-glucans), superoxide dismutase (SOD), and triterpenes. Its ORAC (Oxygen Radical Absorbance Capacity) score is among the highest of any natural food or supplement.
Traditional use of chaga spans centuries in Siberian, Finnish, and Russian folk medicine, where it was consumed as a tea to support vitality, immune function, and longevity. While much of the current research interest focuses on chaga's immunomodulatory and anti-cancer properties, emerging research suggests significant neuroprotective potential. A 2019 study in International Journal of Medicinal Mushrooms found that chaga polysaccharides protected hippocampal neurons from oxidative stress-induced apoptosis. Additional research shows that chaga's anti-inflammatory compounds reduce neuroinflammation by inhibiting NF-kB activation and reducing iNOS expression in microglial cells.
- Superoxide dismutase (SOD): Contains exceptionally high levels of this primary antioxidant enzyme that neutralises superoxide radicals in neural tissue
- Melanin complex: The dark pigment in chaga has potent free radical scavenging capacity and may protect against UV and radiation damage
- Beta-glucan immunomodulation: Polysaccharides modulate immune function, enhancing defence when needed and reducing overactivation (neuroinflammation) when appropriate
- NF-kB inhibition: Betulinic acid and triterpenes inhibit the NF-kB inflammatory pathway, reducing chronic neuroinflammation
- Betulinic acid neuroprotection: Derived from the birch bark host, this compound exhibits anti-inflammatory, antiviral, and anti-apoptotic properties in neural tissue
- Mitochondrial support: Antioxidant compounds protect mitochondrial membranes from oxidative damage, supporting neuronal energy production
- Standard dosage: 500-2,000 mg of chaga extract per day
- Extract type matters: Hot water extracts release beta-glucans; dual-extraction (hot water + alcohol) captures both water-soluble and fat-soluble compounds
- Traditional preparation: Chunks of chaga simmered for several hours to make a dark, coffee-like tea
- Timing: Can be taken any time of day. Chaga tea is commonly used as a morning coffee alternative
- Quality: Wild-harvested chaga from birch trees is preferred over cultivated mycelium-on-grain products, which contain far fewer active compounds
- Generally well tolerated: Long history of traditional use as a food/tea with minimal adverse effects reported
- Oxalate content: Chaga contains significant oxalates. People with kidney disease, kidney stones, or oxalate sensitivity should avoid high-dose supplementation
- Blood thinning: May have mild anticoagulant properties - use caution before surgery or if taking blood-thinning medications
- Blood sugar: May lower blood glucose - monitor if diabetic or taking hypoglycaemic medications
- Autoimmune conditions: As an immune modulator, consult a healthcare provider before use if you have an autoimmune condition
- Sustainability: Wild chaga is slow-growing and over-harvested in some regions. Source from sustainable suppliers
Natural Sources & Forms
- Wild-harvested chaga chunks: Available from mushroom and herbal suppliers; best simmered as tea
- Dual-extraction tinctures: Liquid extracts capturing both water-soluble and fat-soluble compounds
- Capsules and powder: Standardised extracts available from functional mushroom brands (Four Sigmatic, Real Mushrooms, etc.)
- Chaga coffee blends: Pre-mixed with instant coffee for convenience
