HelloPharmacist Scorecard of Turkey Tail Mushroom by Hawaii Pharm

Four independent checks of what is known — a summary of the available information, not a grade of the product itself.

Evidence for Intended Use
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

The stated purpose hasn't been mapped to our evidence data yet.

Why this rating?
  • We haven't mapped this product's purpose to our evidence data yet — it'll be graded on the next content refresh.
Ingredient Transparency
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.
Known Interaction Concern
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Turkey Tail Mushroom.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 187 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.
Safety Information
Well characterized

Why this rating?

  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.

Assessment coverage: 1 of 1 active ingredient matched to our full ingredient reviews (monographs). Based on the product label dated Oct 24, 2023.

Turkey Tail Mushroom Extract, Dry4 drug types · 187 drugs

Antidiabetes Drugs

Theoretically, taking turkey tail mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research suggests that turkey tail mushroom and a polysaccharide component can have hypoglycemic effects.

Likelihood Possible Evidence D
Cyclophosphamide

Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might increase exposure to cyclophosphamide.
Some animal research shows that the PSP component of turkey tail mushroom can increase the area under the concentration-time curve (AUC) of cyclophosphamide by 44% to 50% and the half-life by 34% to 43%. This interaction could potentially increase the effects and adverse effects of cyclophosphamide. However, it is not known whether PSP affects the levels of the active metabolites of cyclophosphamide that are responsible for its clinical activity.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might interfere with the absorption of tamoxifen.
Animal research suggests that PSP increases the time to reach maximum concentration of a single dose of tamoxifen by about 9.5 hours, or 228%. When repeated doses of tamoxifen were given, the time to reach maximum concentration was increased by about 5.6 hours, or 93%. However, PSP did not affect the maximum concentration or the area under the curve of tamoxifen.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might inhibit CYP2C9.
Laboratory research suggests that the PSP component of turkey tail mushroom dose-dependently inhibits CYP2C9. Theoretically, taking PSP with drugs metabolized by CYP2C9 might increase drug levels and the risk of adverse effects. However, this has not been reported in humans.
