HelloPharmacist Scorecard of Cordyceps 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 11, 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 is a single-ingredient supplement: cordyceps, a type of fungus (mushroom). The powder form means the cordyceps extract is dried and ground into a fine powder you can mix into liquid or food.

There are no inactive ingredients listed for this product — you're getting cordyceps and nothing else.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Cordyceps's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: support respiration, energy, stamina, and endurance.
  • We looked for evidence on: Athletic performance, Fatigue, Asthma, Cough, Exercise capacity, Physical exertion tolerance.
  • The closest evidence on file: Cordyceps is rated "Possibly Ineffective" for Athletic performance (Natural Medicines).
  • Also on file: Cordyceps is rated "Insufficient Reliable Evidence To Rate" for Asthma, Cough, Fatigue.

The evidence for cordyceps is thin. For athletic performance, the data suggests it's possibly ineffective.

For sexual dysfunction, asthma, COPD, arrhythmia, and lung cancer, there simply isn't enough reliable evidence to rate whether it works. If any of those are why you're considering it, talk with us before you buy — we can point you toward what the research actually supports.

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 the overall safety data is limited and product quality varies quite a bit. The most common side effects are mild — abdominal discomfort, constipation, and diarrhea — and tend to be uncommon.

Taking it with food can help reduce these. One isolated case report described liver inflammation in someone taking a cordyceps product, but it's unclear whether cordyceps itself was responsible or a contaminant in that particular batch.

There isn't enough safety data for pregnancy or breastfeeding — the recommendation is to avoid it during both unless your doctor advises otherwise. If you're pregnant, trying to conceive, or nursing, talk with us or your OB first.

Side effects, ingredient by ingredient Cordyceps

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.

Double-check this product if you're on blood thinners or antiplatelet drugs (like warfarin, aspirin, or clopidogrel), immunosuppressants (especially after a transplant), or testosterone therapy. No interactions are documented for the ingredients we could not check, but be sure to verify your specific medications using the tool on this page.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Cordyceps might appeal if you're exploring mushroom supplements for general wellness, though the evidence for specific uses is weak or missing. If you take blood thinners, immunosuppressants, or testosterone therapy, you need to check with your pharmacist or doctor before starting.

Same goes if you're pregnant or breastfeeding.

Cordyceps3 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.

Cordyceps by Host Defense Mushrooms: Common Questions

Does Cordyceps by Host Defense Mushrooms interact with any medications?
Yes. Based on its ingredients, Cordyceps has a known interaction with 249 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cordyceps contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
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.
What exactly is cordyceps?
Cordyceps is a fungus — essentially a medicinal mushroom. Host Defense has dried and ground it into a powder you can mix into drinks or food.
Will this help with my athletic performance?
The research suggests cordyceps is likely not effective for athletic performance. If boosting endurance or strength is your goal, we'd recommend asking us about options with better evidence behind them.
What side effects should I watch for?
Most people tolerate it fine, but abdominal discomfort, constipation, and diarrhea can happen — though they're uncommon. If you do get an upset stomach, try taking it with a meal.
Is it safe to use during pregnancy or while breastfeeding?
There isn't enough safety data to know either way. The safety data advises against using cordyceps during pregnancy and breastfeeding. Talk with your OB or pharmacist for personalized advice before starting.
How long does it take to work?
The facts we have don't speak to onset time. That's something to ask your pharmacist about based on what you're hoping to use it for.
Does this product have any fillers or inactive ingredients?
No — this powder is cordyceps only, with no fillers, binders, or other inactive ingredients added.
