HelloPharmacist Scorecard of Mushroom Complex by Nature's Craft

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 4 of its 10 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (266 mg) without saying how much of each component you get.

Nature's Craft Mushroom Complex contains 10 active mushroom ingredients: maitake, chaga, black fungus, reishi, shiitake, white button mushroom, cordyceps, lion's mane, turkey tail, and royal sun agaricus. Most are extracts from the fruiting bodies of these mushrooms, which contain the compounds traditionally used in herbal practice.

The product also contains inactive ingredients—cellulose, microcrystalline cellulose, and magnesium stearate—that help form and stabilize the capsule.

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: Immune support and general wellness.
  • We looked for evidence on: Common cold, Influenza, Fatigue, Chronic fatigue syndrome (CFS), Cancer, Chemotherapy-induced adverse effects — and 4 related terms.
  • The closest evidence on file: Maitake Mushroom is rated "Insufficient Reliable Evidence To Rate" for Chemotherapy-induced anemia (Natural Medicines).
  • Also on file: Maitake Mushroom is rated "Insufficient Reliable Evidence To Rate" for Laryngeal cancer, Chemotherapy-induced diarrhea, Chronic fatigue syndrome (CFS), Chemotherapy-related fatigue, and more.

The evidence is thin across the board. For maitake, the effectiveness ratings we hold show insufficient reliable evidence for hay fever, anemia, cancer, and chronic fatigue.

Chaga shows insufficient evidence for heart disease, diabetes, and COVID-19. Reishi is rated possibly ineffective for high cholesterol (hyperlipidemia) and shows insufficient evidence for altitude sickness, Alzheimer's, and athletic performance.

Shiitake is possibly ineffective for dental plaque and has insufficient evidence for anemia, atherosclerosis, breast cancer, and chemotherapy side effects. White button mushroom, cordyceps, and lion's mane all carry insufficient evidence ratings for their listed uses.

In short, we don't have reliable data showing these mushrooms work for any of the conditions listed in our files.

The evidence, ingredient by ingredient Maitake Mushroom Chaga Agaricus Mushroom Reishi Mushroom Shiitake Mushroom Cordyceps Lion's Mane 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 7 of the 7 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 7.
  • General safety write-ups exist for 7 of 7.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these mushrooms are generally well tolerated when eaten as food, but concentrated supplements are a different story—safety data are limited. The most common side effects across the ingredients are digestive: diarrhea, nausea, abdominal discomfort, and bloating appear in the adverse-effects data for maitake, reishi, shiitake, white button mushroom, cordyceps, and lion's mane.

Reishi may cause dizziness, dry mouth, itching, or rash. Shiitake can cause a rare but distinctive skin reaction called shiitake dermatitis if the raw mushroom is eaten.

White button mushroom and cordyceps carry rare reports of serious liver problems, though these are uncommon. Because safety data for concentrated supplements are not well established and pregnancy and breastfeeding safety data are insufficient for maitake, chaga, reishi, shiitake, white button mushroom, cordyceps, and lion's mane, anyone pregnant or nursing should talk with their doctor or pharmacist before taking this product.

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?
  • 7 of the 7 matched ingredients can interact with medications — Maitake Mushroom, Cordyceps, Shiitake Mushroom, Reishi Mushroom, Agaricus Mushroom, among others.
  • 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: 662 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 the following medication types: blood pressure medications (antihypertensive drugs), blood thinners and antiplatelet drugs (anticoagulants/antiplatelet agents), diabetes medications, immune-suppressing drugs (immunosuppressants), warfarin specifically, and any drug metabolized by the liver enzyme CYP2D6. Because we could not check three ingredients in the blend—black fungus, turkey tail, and royal sun agaricus—there may be additional interactions we're unaware of.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This is a multi-ingredient mushroom blend that may interact with blood pressure medications, blood thinners, diabetes drugs, immune-suppressing medications, and a few other drug types. If you take any prescription medications, check each one against the tool on this page before starting.

People pregnant or breastfeeding should get personalized advice from their doctor or pharmacist. We can't verify the effectiveness of these mushrooms for any condition, and common side effects include digestive upset.

Reishi Mushroom Fruit Extract3 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

Chaga Mushroom Fruit Extract3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, chaga may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that chaga extract can inhibit platelet aggregation. This effect has not been reported in humans.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, taking chaga with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research suggests that chaga might decrease blood glucose levels and increase insulin levels. This has not been reported in humans.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, chaga might interfere with immunosuppressive therapy.
In vitro research suggests that certain constituents of chaga stimulate immune function. This has not been reported in humans.

Lion's Mane3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, lion's mane mushroom may increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
In vitro research suggests that lion's mane mushroom extracts can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, lion's mane mushroom may have additive effects when used with antidiabetes drugs.
Animal research suggests that an aqueous extract of lion's mane mushroom can reduce serum glucose and increase serum insulin.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, concurrent use of lion's mane mushroom might interfere with immunosuppressive therapy.
In animal and in vitro research, lion's mane mushroom polysaccharides stimulate the immune system.

Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, shiitake mushroom might decrease levels of drugs metabolized by CYP2D6.
In vitro studies suggest that the shiitake mushroom extract AHCC might induce the CYP2D6 enzyme. This effect has not been reported in humans.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, taking shiitake mushroom might decrease the effects of immunosuppressive therapy.
In vitro evidence suggests that shiitake mushroom extracts stimulate immune function.

Likelihood Possible Evidence D

Maitake Mushroom Fruit Extract3 drug types · 260 drugs

Antidiabetes Drugs

Theoretically, combining maitake mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that taking maitake mushroom polysaccharide (MMP) can lower blood glucose levels in patients with types 2 diabetes.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, combining maitake mushroom with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that maitake mushroom can lower blood pressure.

Likelihood Possible Evidence D
Warfarin (Coumadin)

There is limited evidence that maitake mushroom may increase the anticoagulant effects of warfarin.
In a case report, a patient previously stabilized on warfarin developed an elevated international normalized ratio (INR) of 5.1 after taking maitake mushroom (Grifron-Pro Maitake D-Fraction) 1 drop/kg daily in three divided doses for one week. The elevated INR resolved after holding warfarin for two days, then reducing the dose by 11%. It is thought that the beta-glucan constituent of maitake mushroom might cause warfarin dissociation from proteins, resulting in increased free warfarin levels and increased warfarin effects.

Likelihood Possible Evidence D
Maitake Mushroom Fruit Extract full monograph & interactions

Cordyceps sinensis, Powder3 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.

Likelihood Possible Evidence D
Cordyceps sinensis, Powder full monograph & interactions

White Button Mushroom Fruit Extract1 drug type · 86 drugs

Antidiabetes Drugs

Theoretically, taking agaricus mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
In one clinical study in patients with type 2 diabetes who are stabilized on conventional oral hypoglycemic agents, 3 of 29 patients taking an agaricus mushroom extract 500 mg three times daily for 12 weeks reported hypoglycemia, compared to one of 29 patients in the placebo group.

Mushroom Complex by Nature's Craft: Common Questions

Does Mushroom Complex by Nature's Craft interact with any medications?
Yes. Based on its ingredients, Mushroom Complex has a known interaction with 662 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Mushroom Complex contains 10 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 blood pressure or diabetes medication?
Not without checking first. Multiple mushrooms in this blend—maitake, chaga, reishi, white button mushroom, and lion's mane—may lower blood pressure or blood sugar, which could add to your medication's effect and cause problems. Run your exact medications through the checker on this page, and talk to your pharmacist or doctor before starting.
What are the main side effects I might notice?
Digestive upset is the most common—diarrhea, nausea, stomach discomfort, and bloating show up across several of the mushroom ingredients. Reishi may cause dizziness, dry mouth, or rash. Most side effects are mild, but if you experience severe diarrhea or signs of liver problems (jaundice, dark urine), stop and contact your doctor.
Is this safe to take while pregnant or breastfeeding?
The safety data aren't there—for most of these mushrooms, we don't have enough information to say it's okay. If you're pregnant or nursing, talk with your doctor or pharmacist before taking this product; they can give you personalized advice based on your situation.
Does this product actually work for anything?
Our data show insufficient reliable evidence for the conditions these mushrooms are traditionally used for—hay fever, cancer, cognitive function, athletic performance, and many others. In other words, we don't have solid proof they work for any of these uses.
Why does this interact with so many medications?
The product has 10 different mushroom ingredients, each with its own compounds. Several of them—maitake, chaga, reishi, and others—can affect blood pressure and blood sugar, which is why they clash with drugs that do the same thing. One interacts with blood thinners, and some may affect how your liver processes certain medications.
What if I'm taking one of the three mushrooms you couldn't check?
We hold no interaction data for black fungus, turkey tail, or royal sun agaricus, so we can't tell you whether they're safe with your medications. That doesn't mean they're safe—it just means we don't have the information. Mention those ingredients to your pharmacist when you check your medications.
