HelloPharmacist Scorecard of Cordychi 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

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Cordychi contains 2 active ingredients: cordyceps and reishi mushroom. Both are whole-mushroom extracts designed to support overall wellness.

The capsule itself is made from pullulan, an inactive ingredient.

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.

Why this rating?
  • The label markets this product for: Supports stress and fatigue reduction.
  • We looked for evidence on: Fatigue, Stress, Cancer-related fatigue, Chronic fatigue syndrome (CFS), Fibromyalgia, Psychological well-being — and 4 related terms.
  • The closest evidence on file: Cordyceps is rated "Insufficient Reliable Evidence To Rate" for Fatigue (Natural Medicines).
  • Also on file: Reishi Mushroom is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Cancer-related fatigue, Fibromyalgia, Insomnia, and more.

The evidence for what cordyceps and reishi actually do is mixed and often limited. For cordyceps, athletic performance has been rated possibly ineffective — it doesn't seem to help much there.

Sexual function, heart rhythm problems, asthma, and lung conditions don't have enough reliable evidence to rate either way. For reishi, high cholesterol (hyperlipidemia) rates as possibly ineffective, and altitude sickness, Alzheimer's disease, and athletic performance don't have enough solid evidence to know if it works.

The evidence, ingredient by ingredient Cordyceps Reishi Mushroom

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both cordyceps and reishi are generally well tolerated in the short term, though cordyceps data is limited and product quality varies widely. The most common side effects from cordyceps are belly discomfort, constipation, and diarrhea — these can sometimes be reduced by taking it after a meal.

Reishi may cause dizziness, dry mouth, itching, nausea, rash, or stomach upset; respiratory allergies to reishi spores, sore throat, and runny nose have also been reported. There's one older case report of liver inflammation (hepatitis) possibly linked to a cordyceps product, though it's unclear whether cordyceps itself or a contaminant caused it.

During pregnancy and breastfeeding, there isn't enough safety data for either ingredient, so they're best avoided.

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?
  • 2 of the 2 matched ingredients can interact with medications — Cordyceps, Reishi Mushroom.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 502 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.

Check your medications if you take blood thinners or antiplatelet drugs (like warfarin or aspirin), blood pressure medications, diabetes medications, or immunosuppressants — cordyceps and reishi both have moderate interactions with these. Also mention any testosterone therapy or supplements.

No interactions are documented for the other effects listed, but checking your exact medications with the tool on this page is the safest step.

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.

Cordychi may appeal to you if you're interested in mushroom-based supplements, but the evidence that it actually works for most conditions isn't strong. If you take blood thinners, blood pressure medications, diabetes drugs, or immunosuppressants, talk to your pharmacist or doctor before starting this — the interactions are real enough that you'll want personalized advice.

Avoid it if you're pregnant or breastfeeding.

Each ingredient & the kinds of drugs it affects

For each ingredient in Cordychi with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Reishi3 drug types · 375 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, high doses of reishi mushroom might increase the risk of bleeding.
A dose of 1.5 grams daily of reishi mushroom does not seem to decrease platelet aggregation, but a higher dose of 3 grams daily does.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, reishi mushroom might have additive effects with antidiabetes drugs.
Animal research suggests that reishi mushroom decreases blood sugar. However, in patients with type 2 diabetes, taking reishi mushroom does not reduce fasting glucose levels, and its effects on glycated hemoglobin are inconsistent.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, concurrent use of reishi mushroom with antihypertensive drugs might increase the risk of hypotension.
Reishi mushroom has shown hypotensive activity in animal research. Clinical evidence suggests that reishi mushroom reduces blood pressure in some, but not all, patients with hypertension.

Likelihood Possible Evidence D

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.

Cordychi by Host Defense Mushrooms: Common Questions

Does Cordychi by Host Defense Mushrooms interact with any medications?
Yes. Based on its ingredients, Cordychi has a known interaction with 502 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cordychi contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Can I take this if I'm on a blood thinner like warfarin or aspirin?
Not without talking to your pharmacist first. Both cordyceps and reishi may theoretically increase bleeding risk — cordyceps through platelet effects, and reishi at higher doses. This hasn't been reported in humans yet, but it's real enough that you need a personalized conversation about whether it's safe for you.
What's the most common side effect I might see?
From cordyceps, it's belly discomfort, constipation, or diarrhea. From reishi, dizziness and dry mouth are most common. Try taking cordyceps after a meal to see if that helps. Both mushrooms are generally well tolerated, though.
Does cordyceps really improve athletic performance?
The evidence says it's probably not effective for that. Studies haven't shown a real benefit, so if athletic performance is your main reason for trying this, the science doesn't back it up.
Is it safe to take during pregnancy?
No, not based on the safety data we have. There isn't enough information to know if either cordyceps or reishi is safe while pregnant, so they're best avoided. Talk to your OB or pharmacist about what's safe for you.
Can I take this with my blood pressure medication?
Reishi can theoretically lower blood pressure further on top of your medication, which could be a problem. Check with your pharmacist before starting — they can tell you if your specific medication and dose make this risky for you.
Will this help with my high cholesterol?
The evidence says reishi is probably not effective for cholesterol levels, so it's not a reliable choice if that's your goal. Talk to your doctor about proven options instead.
