HelloPharmacist Scorecard of Cordyceps Mushroom by Fresh Nutrition

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: organic cordyceps mushroom, a fungus traditionally used to support energy and stamina. The capsule itself is made from vegetarian material (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 — see Cordyceps's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Cordyceps mushroom for energy and immune support.
  • We looked for evidence on: Fatigue, Athletic performance, Asthma, Cough, stamina, endurance — and 1 related terms.
  • 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 mixed. For athletic performance, current data suggests it's possibly ineffective.

For sexual dysfunction, asthma, arrhythmia (irregular heartbeat), chronic obstructive pulmonary disease (COPD), and lung cancer, there simply isn't enough reliable evidence to say whether it works or doesn't. If you're considering cordyceps for any of these reasons, the science doesn't yet back it up.

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 for up to a year, though the overall safety data is limited and product quality varies widely between brands. The most common side effects are mild—abdominal discomfort, constipation, or diarrhea—and these are uncommon; taking it with food may help reduce them.

There's one case report of liver inflammation (cholestasis) in someone taking a cordyceps product, but it's unclear whether cordyceps itself was the cause or a contaminant in that particular supplement. Because there isn't enough safety data, the evidence advises against cordyceps during pregnancy and while breastfeeding.

Talk with your doctor or pharmacist about whether it's right for you.

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.

Before taking this product, check with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs (a moderate interaction), immunosuppressants (moderate), or testosterone therapy (minor). No interactions are documented for the ingredient we could check beyond those listed.

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 may be worth considering if you're interested in a traditional energy supplement, but the evidence for athletic performance or other health claims isn't strong. If you take blood thinners, immunosuppressants, or testosterone therapy, you'll want to check with your doctor or pharmacist before starting.

Given the gaps in safety data, it's best to skip it during pregnancy or while breastfeeding.

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 Mushroom by Fresh Nutrition: Common Questions

Does Cordyceps Mushroom by Fresh Nutrition interact with any medications?
Yes. Based on its ingredients, Cordyceps Mushroom 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 Mushroom 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.
Is cordyceps safe to take during pregnancy?
No, there isn't enough safety data to know, so the evidence advises against it. Talk with your doctor or pharmacist for personalized advice.
Can I breastfeed while taking cordyceps?
The safety data isn't there to say it's safe while breastfeeding, so it's best avoided. Check with your doctor or pharmacist for guidance on your situation.
Does cordyceps actually help athletic performance?
The current evidence suggests it's possibly ineffective for athletic performance. If you're looking for a supplement to boost workout results, this one isn't backed by strong science.
What are the side effects?
Most people tolerate it well, but some experience mild abdominal discomfort, constipation, or diarrhea—and these are uncommon. Taking it with food may help. There's one case report of liver inflammation, though it's unclear if cordyceps was the cause.
Can I take cordyceps if I'm on warfarin or another blood thinner?
Lab research suggests cordyceps might slow blood clotting, which could increase bleeding risk with these drugs. Don't start it without checking with your doctor or pharmacist first.
Does quality vary between brands?
Yes—product quality varies widely, so you may want to research the brand you're considering and look for third-party testing if available.
