What’s In It
Active ingredient: Organic Chaga (Inonotus obliquus) Mushroom Mycelium Powder, standardized to 40% polysaccharides (400mg per serving)
Inactive ingredients: Vegan capsule (modified cellulose, water), silica
Two important things to flag immediately about the formula — one positive, one context-setting.
The positive: 40% polysaccharide standardization is a meaningful quality marker. Most chaga products don’t specify polysaccharide content at all. Standardization means the extract has been processed to consistently deliver a defined compound concentration, not just a fixed weight of raw powder. This is the type of specification that separates a measured supplement from a commodity ingredient.
The context: This product specifies “mycelium powder” rather than fruiting body extract. For chaga specifically, this deserves explanation. Chaga is unusual among functional mushrooms: what’s harvested and used medicinally is technically the sclerotium (a hardened fungal mass), not a traditional fruiting body in the way lion’s mane or reishi form one. Some suppliers classify chaga material differently depending on how the fungal structure is categorized. The key quality question — as with all mushroom products — is whether the material contains meaningful concentrations of active compounds. The 40% polysaccharide standardization answers that question affirmatively: this product has been assayed and confirmed to deliver a defined beta-glucan and polysaccharide concentration per serving.
Evidence Alignment
Chaga’s research-supported applications are antioxidant support (driven by melanin and polyphenols) and immune modulation (driven by polysaccharides). The 40% polysaccharide standardization directly addresses the immune-modulatory compound fraction. The antioxidant profile is intrinsic to well-sourced chaga material and not dependent on specific processing claims.
The published research on chaga polysaccharides has used preparations at varying concentrations — the 400mg per 2-capsule serving at 40% standardization places this product within a range that aligns with research dosing contexts. This is ingredient-level alignment, not a finished-product efficacy claim.
For a detailed review of chaga’s research — including honest assessment of where the evidence is strong (antioxidant profile, preclinical immune data) and where it’s limited (human clinical trials) — see our Chaga Research Guide.
Who This Is For
Single-ingredient chaga makes sense for three types of users:
- Focused supplementers who want targeted chaga support — primarily antioxidant and immune maintenance — without a multi-species stack
- Stack builders who already take other functional mushrooms (lion’s mane, reishi, cordyceps) and want to add concentrated chaga as a specific layer
- Consistent traditionalists who prefer capsule format for its simplicity and dosing precision over gummies or tinctures
Users who want broader mushroom coverage should consider the Mushroom Gummies which include chaga alongside nine other species. This standalone chaga product is for those who specifically want chaga as the primary focus.
Practical Notes
Two capsules daily, with or without food. The vegan capsule shell (modified cellulose) dissolves readily in stomach acid. Silica is a standard flow agent used in capsule manufacturing — it ensures the powder fills the capsule consistently and has no pharmacological activity.
The oxalate consideration worth knowing: chaga contains oxalates, and individuals with a history of calcium oxalate kidney stones or existing kidney conditions should consult a healthcare provider before supplementing. This is a species-level consideration that applies regardless of brand or product form.
Bottom Line
The 40% polysaccharide standardization is the defining quality feature of this product — it’s the marker that separates a well-specified supplement from an unmarked powder. The chaga research base is solid on antioxidant activity and promising (if less human-trial-developed) on immune modulation. Clean inactive ingredient profile, vegan capsule, organic source material. A straightforward, well-specified single-ingredient option for chaga specifically.
