HelloPharmacist Scorecard of Cordyceps Extract by Host Defense Mushrooms

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 Jul 16, 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.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: fresh Cordyceps (Cordyceps militaris) mycelium extract. Cordyceps is a fungus traditionally used to support energy and stamina.

The liquid also includes water, alcohol, and myceliated brown rice as inactive ingredients — these are carriers and processing aids, not therapeutic ingredients.

Does it work?

No specific claim
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
General wellness

This Cordyceps product is marketed for general wellness, not a specific health condition, so there's no single claim to grade — see Cordyceps's own graded uses on its monograph.

Why this rating?
  • The label markets general wellness (“Energy support”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.

The evidence on cordyceps is patchy. For athletic performance, the data suggests it's possibly ineffective — meaning the research doesn't support the claim that it boosts sports endurance or strength.

For sexual dysfunction, arrhythmia, asthma, lung cancer, and chronic obstructive pulmonary disease (COPD), there isn't enough reliable evidence in our data to rate whether cordyceps works. That doesn't mean it's ineffective for those uses; it means the studies we have aren't strong enough yet to say either way.

The evidence, ingredient by ingredient Cordyceps

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.

Cordyceps is generally well tolerated when taken by mouth for up to a year, though evidence is limited and product quality varies quite a bit. The most common side effects are mild — abdominal discomfort, constipation, and diarrhea — and they're uncommon.

Taking cordyceps with food may help reduce these. There's one case report of liver inflammation (cholestasis) in a 64-year-old man, but it's unclear whether cordyceps or a contaminant caused it; he recovered after stopping the supplement.

During pregnancy and breastfeeding, there isn't enough safety data, so it's best to avoid cordyceps. If you're pregnant, nursing, or planning either, talk to your doctor or pharmacist before starting.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
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 — Cordyceps.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs.
  • For scale: 249 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.

Before taking this cordyceps product, check with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs (warfarin, clopidogrel, aspirin) — there's a Moderate risk that cordyceps could increase bleeding. Also double-check if you take immunosuppressants like cyclosporine, as cordyceps may interfere with how well they work.

If you're using testosterone therapy, that's also worth confirming, though the interaction is Minor in severity.

The bottom line

Scorecard at a glanceFully disclosed formula marketed for general wellness rather than one specific gradeable purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Cordyceps Extract is used by some for athletic stamina and energy, but the evidence doesn't support that claim. If you take blood thinners, immunosuppressants, or testosterone therapy, you should check with your doctor or pharmacist before starting cordyceps — the interaction risk is real enough to warrant a conversation.

For most people without those medications, cordyceps is generally well tolerated short-term, though you should know the evidence on effectiveness is limited and quality can vary.

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.

Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
