HelloPharmacist Scorecard of Organic Cordyceps Mushroom Extract 500 mg by Dr. Mercola

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Oct 8, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
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.
  • “Cordyceps Mushroom Fruitbody Extract” is listed as a grouped ingredient — the label gives one combined amount (500 mg) without saying how much of each component you get.

The active ingredient listed is beta-glucan, a type of fiber found in mushrooms, grains, and other foods. Beta-glucans are the component this page's interaction and effectiveness data is based on.

The product also lists a Cordyceps Mushroom Fruitbody Extract, which we could not characterize further from the data we hold. The inactive ingredients are pullulan, rice hull, rice extract, gum acacia, and sunflower oil.

These are fillers and capsule or binding materials that help form the capsule and are not expected to add therapeutic effect.

Does it work?

Strong evidence
Evidence for Intended Use · database check
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

This product doesn't appear to be marketed for a specific use, so we graded Beta-glucans's overall clinical evidence instead.

Strong

Strong clinical evidence supports Beta-glucans for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Coronary heart disease (CHD) — rated "Likely Effective" (Natural Medicines).
  • On file: Dyslipidemia — rated "Likely Effective" (Natural Medicines).

The beta-glucan ratings we hold show it as Likely Effective for dyslipidemia (abnormal blood fats) and for coronary heart disease (CHD). These ratings come from the beta-glucan data, not from clinical trials of this exact capsule.

They do not guarantee results for you.

The evidence, ingredient by ingredient Cordyceps Beta-glucans

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Beta-glucans from food sources are generally well tolerated by most people. Our data notes that concentrated supplements lack safety data, so caution is advised with this extract.

Side effects we hold include skin reactions and contact dermatitis (an itchy rash) with topical beta-glucan products. In one trial of children and young adults with neuroblastoma, a single patient had temporary liver enzyme elevations after starting oral beta-glucans.

For breastfeeding, there is little research on supplement doses, so caution is advised. For pregnancy, no safety data is on file for this ingredient, so talk with your doctor or pharmacist for personalized advice.

Meds to double-check

Moderate interaction found

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 — Beta-glucans.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 293 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.

Double-check with your doctor or pharmacist before taking this product if you take antihypertensive drugs (blood pressure medicines) or immunosuppressants (medicines that dampen the immune system). Both interactions are rated Moderate in our data.

Cordyceps Mushroom Fruitbody Extract3 drug types · 249 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, cordyceps may increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
In vitro and animal research suggests that cordyceps extract inhibits platelet aggregation and function. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, concurrent use of cordyceps might interfere with immunosuppressive therapy.
Animal and in vitro research suggests that cordyceps stimulates the immune system. However, limited clinical research suggests that taking cordyceps may lower the necessary therapeutic dose of the immunosuppressant cyclosporine, which suggests that cordyceps may have an immunosuppressive effect.

Likelihood Possible Evidence B
Testosterone

Theoretically, concurrent use of cordyceps and testosterone might have additive effects.
Animal research suggests that cordyceps can increase testosterone levels. The clinical significance of this finding is unclear.
