Chaga is the dark, charcoal-coloured conk that grows on living birch trees in the world's coldest forests. It is technically a parasitic fungus, slow-growing, and prized for the dense polysaccharide and melanin content it accumulates over decades.
Folk medicine across Russia, Scandinavia and North America has used chaga as a tea for immune support and as an antioxidant tonic.
How it works in the body
Chaga is one of the most antioxidant-dense foods known by ORAC measurement. Its beta-glucans support immune responsiveness; its melanins and triterpenes account for much of its antioxidant activity.

04 — PROTOCOL
1–2 g daily, brewed long as tea or taken as dual-extract powder.
05 — SOURCING
Wild-harvested whole conk, dual-extracted. Avoid mycelium-on-grain; chaga's actives concentrate in the wild conk.
06 — CAUTION
Contains oxalates — those with a history of kidney stones should be careful. May interact with anticoagulants and insulin therapy.
What the studies say
Chaga (Inonotus obliquus) is exceptionally rich in melanin polymers, β-glucans and triterpenes. Mechanistic and pre-clinical data are extensive; controlled human-trial data is still developing.
Honest caveatMost published evidence is mechanistic / pre-clinical. We do not make disease-treatment claims for chaga.
