Chaga is a parasitic birch tree fungus with the highest ORAC antioxidant value of any food (146,700 vs blueberries at 4,669). Contains betulinic acid (anti-cancer — induces apoptosis), melanin (radioprotective), and polysaccharides (immune-modulating). Traditional Siberian folk remedy. ZERO human clinical trials. The 'superfood' marketing massively outpaces the evidence. CAUTION: contains high oxalates — case reports of oxalate nephropathy (kidney failure) from chronic high-dose chaga consumption. Not recommended long-term at high doses. --- *Reviewed by the Dose AI Research Team and Clinical Advisory Board* *Last updated: 2026-04-06*
