HelloPharmacist Scorecard of 5 Defenders Powder by Real 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

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 1 of its 6 active ingredients.
  • “5 Defenders Extract Blend” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

5 Defenders Powder contains 6 active ingredients, all mushroom extracts: maitake, shiitake, beta-1,3-1,6-glucan, turkey tail, reishi, and chaga. There's also a "5 Defenders Extract Blend" listed as a container for some of these.

No inactive ingredients (fillers, binders, or capsule material) are listed for this product.

Does it work?

Moderate evidence
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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Immune strength and wellness support.
  • We looked for evidence on: Allergic rhinitis (hay fever), Asthma, Bronchitis, Cancer, Cancer-related fatigue, Chemotherapy-induced anemia — and 4 related terms.
  • The strongest evidence on file: Turkey Tail Mushroom is rated "Possibly Effective" for Cancer (Natural Medicines).
  • Also on file: Maitake Mushroom is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever), Chemotherapy-induced anemia, Laryngeal cancer, Chemotherapy-induced diarrhea, and more.

The evidence for what this powder actually does is mixed and often thin. Beta-glucans are rated Likely Effective for heart health and cholesterol—that's the strongest claim here.

Turkey tail is Possibly Effective for cancer support. For everything else—maitake on allergies or fatigue, shiitake on cancer or heart disease, reishi on sleep or altitude sickness, chaga on heart or blood sugar—the evidence isn't established enough to rate.

Most mushroom benefits fall into the "Insufficient Reliable Evidence" bucket, meaning we don't have enough solid human studies to call them effective yet.

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 6 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

When eaten as food, these mushrooms are generally well tolerated. As concentrated supplements, the safety picture is less clear.

The most common side effects are stomach-related: diarrhea, nausea, bloating, and stomach upset. A small number of trial participants reported rash or itching.

Shiitake has a rare but specific risk—eating raw shiitake can cause shiitake dermatitis, a distinctive skin eruption, and handling it extensively can trigger respiratory allergies. Chaga carries a particular caution: excessive consumption has been linked in a few cases to kidney failure because chaga contains high oxalate levels.

The facts don't provide enough data to assess safety during pregnancy or breastfeeding for any of these ingredients—the safety data simply aren't on file.

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?
  • 6 of the 6 matched ingredients can interact with medications — Maitake Mushroom, Turkey Tail Mushroom, Shiitake Mushroom, Reishi Mushroom, Beta-glucans, 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: 696 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, double-check with your pharmacist if you take any of these: warfarin or other blood thinners (anticoagulants) or blood thinners you chew (antiplatelets)—maitake and warfarin is a known concern; blood pressure medications (antihypertensive drugs)—three ingredients may lower it further; diabetes drugs or insulin; cancer medications, especially cyclophosphamide or tamoxifen; immunosuppressants after transplant; or drugs your liver processes through CYP2D6 or CYP2C9 enzymes—ask your pharmacist if you're unsure. These are Moderate severity interactions in the data we hold.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This is a multi-ingredient mushroom blend with real interaction potential, especially if you take blood thinners, blood pressure drugs, diabetes medications, or cancer drugs. The evidence that it works for most claimed benefits isn't strong yet.

If you're considering it, talk to your pharmacist first—particularly if you're on any prescription medications. People with kidney problems should be cautious about chaga specifically.

Each ingredient & the kinds of drugs it affects

For each ingredient in 5 Defenders Powder 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.

Reishi Mushroom 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
Reishi Mushroom Extract full monograph & interactions

Chaga 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.

Likelihood Possible Evidence D
Chaga Extract full monograph & interactions

Shiitake Mushroom Extract2 drug types · 312 drugs

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
Shiitake Mushroom Extract full monograph & interactions

Beta-1,3-1,6-Glucan2 drug types · 293 drugs

Antihypertensive Drugs

Theoretically, taking beta-glucans with antihypertensive drugs might increase the risk of hypotension.
Clinical research shows that taking beta-glucans may reduce systolic and diastolic blood pressure in some hypertensive individuals.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, beta-glucans might interfere with immunosuppressive therapy.
Some clinical research shows that beta-glucans have immunostimulant effects.

Likelihood Possible Evidence D
Beta-1,3-1,6-Glucan full monograph & interactions

Maitake Mushroom 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 extract full monograph & interactions

Turkey Tail Mushroom Extract4 drug types · 187 drugs

Antidiabetes Drugs

Theoretically, taking turkey tail mushroom with antidiabetes drugs might increase the risk of hypoglycemia.
Animal research suggests that turkey tail mushroom and a polysaccharide component can have hypoglycemic effects.

Likelihood Possible Evidence D
Cyclophosphamide

Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might increase exposure to cyclophosphamide.
Some animal research shows that the PSP component of turkey tail mushroom can increase the area under the concentration-time curve (AUC) of cyclophosphamide by 44% to 50% and the half-life by 34% to 43%. This interaction could potentially increase the effects and adverse effects of cyclophosphamide. However, it is not known whether PSP affects the levels of the active metabolites of cyclophosphamide that are responsible for its clinical activity.

Likelihood Possible Evidence D
Tamoxifen (Nolvadex)

Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might interfere with the absorption of tamoxifen.
Animal research suggests that PSP increases the time to reach maximum concentration of a single dose of tamoxifen by about 9.5 hours, or 228%. When repeated doses of tamoxifen were given, the time to reach maximum concentration was increased by about 5.6 hours, or 93%. However, PSP did not affect the maximum concentration or the area under the curve of tamoxifen.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, the polysaccharide peptide (PSP) component of turkey tail mushroom might inhibit CYP2C9.
Laboratory research suggests that the PSP component of turkey tail mushroom dose-dependently inhibits CYP2C9. Theoretically, taking PSP with drugs metabolized by CYP2C9 might increase drug levels and the risk of adverse effects. However, this has not been reported in humans.

5 Defenders Powder by Real Mushrooms: Common Questions

Does 5 Defenders Powder by Real Mushrooms interact with any medications?
Yes. Based on its ingredients, 5 Defenders Powder has a known interaction with 696 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
5 Defenders Powder contains 6 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 warfarin or another blood thinner?
No—not without talking to your doctor or pharmacist first. Maitake in this blend has a documented case of spiking warfarin levels dangerously. Other blood thinners and antiplatelet drugs may also interact with reishi and chaga here. This needs a professional check before you start.
Will this affect my blood pressure medication?
Possibly, yes. Three of the ingredients—maitake, beta-glucans, and reishi—can lower blood pressure on their own. Combined with your medication, your pressure could drop too far. Check with your pharmacist or doctor before adding this.
Is this safe during pregnancy?
There isn't enough safety data on any of these mushroom extracts in pregnancy to know either way. The safety information just isn't on file. Talk with your doctor or pharmacist for personalized advice before taking it while pregnant.
What's the most common side effect?
Stomach upset—diarrhea, nausea, bloating, and stomach discomfort come up most often in the trials. A few people reported rash or itching. Most of these are mild and temporary.
Does this actually work for boosting immunity?
The evidence isn't solid yet. Most of the immunity claims fall into "Insufficient Reliable Evidence," meaning we don't have enough human studies to say it works. Beta-glucans for heart health is the strongest claim in this blend.
Is chaga safe for long-term use?
There are a few cases of kidney failure linked to heavy chaga use because it's high in oxalate. If you have kidney problems or a history of kidney stones, avoid it. Long-term safety in healthy people isn't well studied, so check with your pharmacist.
