Organic Chaga Mushroom Tincture 2oz.

Six-dimension breakdown

Why this scored 58/100

Chaga (Inonotus obliquus) is a wild-harvested (traditionally) or cultivated sclerotial mass that grows primarily on birch trees in cold northern climates. It contains a distinctive suite of triterpenoids (inotodiol, betulinic acid derivatives, ergosterol peroxide), a very high ORAC-measured antioxidant load driven by melanin and polyphenolic compounds, and beta-glucans. In vitro and animal studies show notable antioxidant, immune-modulating, and some cancer-cell-cytotoxic activity; human trial evidence is much thinner — small trials in psoriasis (topical) and inflammatory bowel disease, no large placebo-controlled outcome trials in healthy adults. Two real caveats: chaga is very high in oxalates (contains ~14mg oxalate per gram of dried chaga in some analyses) which has been implicated in at least one case report of chaga-induced oxalate nephropathy in a chronic user with pre-existing kidney disease; and chaga's blood-thinning effect (via ergosterol peroxide and other constituents) means users on warfarin or antiplatelet drugs should avoid it. Mycoterra's fruit-body triple extraction is the appropriate methodology. Standard tier with a modest safety flag reflected in the safety dimension score.

Evidence & sources

The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.

Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

How to read the Evidence dimension

• 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
• 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
• 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
• 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
• 0–19: No credible evidence base or unverifiable claims.
