Chaga Mushroom (Inonotus obliquus)
One of nature's highest antioxidant sources, containing melanin and betulinic acid for immune and inflammatory support.
What the evidence says
Most Chaga studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.
Most evidence is from high-quality randomised trials published 2005–2026 with a typical study size of 80 participants.

LowWhat the studies found
By outcome
Chaga has an evidence score of 7/10 — strong evidence based on 21 indexed studies. One of nature's highest antioxidant sources, containing melanin and betulinic acid for immune and inflammatory support.
The commonly studied dose of Chaga is 1-3g dried mushroom or 500-1500mg extract daily. Research points to an estimated optimal dose around 2000mg, with a minimum effective dose near 1000mg. Individual response varies — start low and adjust.
The best time to take Chaga is in the morning. Taking it with food is preferred. Chaga (Inonotus obliquus) contains immunomodulatory beta-glucans, betulinic acid, and melanin-complex antioxidants.

Chaga is a parasitic fungus that grows on birch trees in cold climates and has been used in Russian and Northern European folk medicine for centuries. It's one of the highest sources of antioxidants in the natural world, containing melanin, beta-glucans, and betulinic acid. Research supports benefits for immune function, inflammation, and oxidative stress.

1-3g dried mushroom or 500-1500mg extract daily
Loading: Not required
Can be taken without food
| Form | Type |
|---|---|
| 💊Dual extraction (hot water + alcohol) extract | Recommended |
| 🍵Dried chunks for tea | Alternative |
| 💊Capsules | Alternative |
| 🧪Powder | Alternative |
Dual extraction ensures both water-soluble (beta-glucans) and alcohol-soluble (betulinic acid) compounds are present.
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: Not required
Note: Traditionally consumed as a tea/decoction. Extracts are more concentrated and convenient.
Evidence limited to systematic reviews without specific RCTs. Effects may vary significantly by extraction method - dual extracts likely more bioavailable than raw powder. Most studies are preclinical or mechanistic.
Enhanced immune function
Reduced oxidative stress markers
Improved energy and stamina
Consult doctor due to immune-modulating effects
May enhance anticoagulant effects
May lower blood sugar; monitor levels
Tip: Start with lower dose
Chaga is generally well-tolerated and considered safe for most healthy adults at recommended doses. The most commonly reported side effects are GI upset. Use caution if any of these apply to you: Bleeding disorders (may have anticoagulant effects).
