Chaga (Inonotus obliquus)
Chaga is a parasitic fungus that grows on birch trees in cold northern climates — and has one of the highest antioxidant ORAC scores of any natural food ever measured. Its unique compounds protect cells from oxidative stress at a level no other mushroom matches.
Key Compounds in Chaga
Chaga's most distinctive compounds include: superoxide dismutase (SOD) — one of the body's primary antioxidant enzymes found at unusually high concentrations in Chaga; melanin — a dark pigment with potent antioxidant and DNA-protective properties; betulinic acid — a triterpene derived from birch bark that Chaga absorbs and concentrates; and beta-1,3/1,6-glucans for immune modulation. Chaga's ORAC (Oxygen Radical Absorbance Capacity) score of approximately 1.5 million per 100g is dramatically higher than common antioxidant foods like blueberries (~4,600) or dark chocolate (~20,000).
Historical Use of Chaga
Chaga has been used in Siberian and Russian folk medicine for centuries, consumed as a tea for digestive health, immune support, and longevity. Finnish and Baltic populations also historically used Chaga as a coffee substitute during wartime rationing. Traditional Siberian hunters and nomads reportedly consumed Chaga tea regularly for sustained energy and cold-weather resilience.
Modern Research on Chaga
Research on Chaga has focused primarily on its antioxidant properties and immune-modulating polysaccharides. A 2010 study published in Biofactors demonstrated Chaga extract's ability to significantly reduce oxidative stress markers in vitro. Research on Chaga's SOD activity suggests it may help regulate cellular oxidative balance, potentially supporting healthy aging processes. Betulinic acid from Chaga has been studied for its effects on cellular health pathways. Note that much Chaga research has been conducted in vitro (cell cultures) — human clinical trials are more limited compared to mushrooms like Turkey Tail and Lion's Mane.
How NüShroom Uses Chaga
Chaga is part of the Daily Defense Gummies 10-in-1 blend. It contributes powerful antioxidant coverage that rounds out the immune-defense spectrum of the gummies. Our hot-water extraction process captures Chaga's water-soluble polysaccharides and polyphenols, while preserving melanin and betulinic acid content.

Shop Daily Defense GummiesDosage & Safety of Chaga
Typical supplemental doses of Chaga extract range from 1,000mg to 2,000mg daily. Chaga is generally well-tolerated. One consideration: Chaga contains high levels of oxalates, which may be a concern for individuals with kidney stones or oxalate sensitivity at very high doses. Standard supplemental doses are not associated with this risk. Consult a healthcare professional if you have kidney concerns.
Chaga FAQ
Why does Chaga have such a high antioxidant score?
Chaga absorbs and concentrates compounds from the birch trees it grows on — particularly betulinic acid and melanin — while also producing exceptionally high levels of superoxide dismutase (SOD), one of the body's primary cellular antioxidant enzymes. The combination of these unique compounds gives Chaga an ORAC score over 1,500,000 per 100g — many times higher than any common food.
Is Chaga safe to take every day?
Yes, at standard supplemental doses. Chaga is generally recognized as safe for daily use. The one caveat: Chaga contains significant oxalate content, which in very high doses could be a concern for individuals prone to kidney stones. Standard supplement doses are well within safe ranges for most people. If you have kidney conditions, consult a healthcare professional.
