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 6 of its 6 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Immuno-Build Mushrooms contains 6 active ingredients: organic cordyceps, organic trametes, organic reishi, organic maitake, organic shiitake, and organic ginger root juice extract. These mushroom species and ginger are included to support immune function, though the evidence for most is still being studied.

The product also contains silica and a capsule as inactive ingredients.

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: support immune health and cellular defense.
  • We looked for evidence on: Acute respiratory distress syndrome (ARDS), Aging, Allergic rhinitis (hay fever), Asthma, Breast cancer, Bronchitis — and 4 related terms.
  • The closest evidence on file: Maitake Mushroom is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever) (Natural Medicines).
  • Also on file: Maitake Mushroom is rated "Insufficient Reliable Evidence To Rate" for Chemotherapy-induced anemia, Laryngeal cancer, Pharyngeal cancer.
  • Also on file: Cordyceps is rated "Insufficient Reliable Evidence To Rate" for Asthma, Lung cancer, Fatigue.

The evidence for most of these ingredients is still incomplete. Ginger has the strongest backing—it's rated Possibly Effective for pregnancy nausea, period cramps (dysmenorrhea), and osteoarthritis.

For the mushrooms, research hasn't yet established whether they work for their intended purpose; most are rated as having Insufficient Reliable Evidence To Rate, meaning we don't have enough solid human trials yet. Cordyceps is rated Possibly Ineffective for athletic performance.

The evidence, ingredient by ingredient Cordyceps Reishi Mushroom Maitake Mushroom Shiitake Mushroom Ginger

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Cordyceps and reishi are generally well tolerated short-term, but long-term safety isn't well studied. The most common side effects are mild—abdominal discomfort, diarrhea, constipation, dry mouth, nausea, dizziness, and rash.

Ginger at typical doses is generally well tolerated, though higher doses (5 grams or more daily) increase the risk of heartburn, burping, and digestive upset. Shiitake as a cooked food is safe, but concentrated supplements carry less safety data.

One rare case of liver inflammation was reported with cordyceps, though whether cordyceps itself was responsible remains unclear. During pregnancy, the safety data for cordyceps, reishi, and maitake concentrated supplements is not established enough to recommend them; talk with your doctor first.

The same applies to breastfeeding.

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?
  • 5 of the 5 matched ingredients can interact with medications — Maitake Mushroom, Cordyceps, Shiitake Mushroom, Reishi Mushroom, Ginger.
  • 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: 1,263 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 you take this product, double-check with your pharmacist if you're on blood thinners or antiplatelet drugs (warfarin, phenprocoumon, aspirin, clopidogrel)—ginger, cordyceps, reishi, and maitake all raise bleeding risk. Blood pressure medications (antihypertensives) are also a concern, as reishi, maitake, and ginger may lower pressure too far.

Diabetes medications and drugs that suppress your immune system need a review as well. Additionally, if you take nifedipine, losartan, or drugs processed through your liver's CYP3A4 or CYP2D6 enzymes, discuss this product with your pharmacist first.

organic Ginger [rhizome] juice extract14 drug types · 1,007 drugs

Anticoagulant/Antiplatelet Drugs

Ginger may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Laboratory research suggests that ginger inhibits thromboxane synthetase and decreases platelet aggregation. However, this has not been demonstrated unequivocally in humans, with mixed results from clinical trials. Theoretically, excessive amounts of ginger might increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking ginger with antidiabetes drugs might increase the risk of hypoglycemia.
Animal and human research suggests that ginger might increase insulin levels and/or decrease blood glucose levels.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Losartan (Cozaar)

Theoretically, ginger might increase levels of losartan and the risk of hypotension.
In animal research, ginger increased the levels and hypotensive effects of a single dose of losartan. It is not clear if ginger alters the concentration or effects of losartan when taken continuously. Additionally, this interaction has not been shown in humans.

Likelihood Possible Evidence D
Nifedipine (Procardia)

Ginger may have antiplatelet effects and increase the risk of bleeding if used with nifedipine.
Clinical research shows that combined treatment with ginger 1 gram plus nifedipine 10 mg significantly inhibits platelet aggregation when compared to nifedipine or ginger alone.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Ginger might increase the absorption and blood levels of P-glycoprotein (P-gp) substrates.
In vitro research and case reports suggest that ginger inhibits drug efflux by P-gp, potentially increasing absorption and serum levels of P-gp substrates. Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are P-gp substrates (trametinib, crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.

Likelihood Possible Evidence D
Phenprocoumon (Marcoumar, Others)

Ginger might increase the risk of bleeding with phenprocoumon.
Phenprocoumon, a warfarin-related anticoagulant, might increase the international normalized ratio (INR) when taken with ginger. There is one case report of a 76-year-old woman with a stable INR on phenprocoumon that increased to greater than 10 when she began consuming dried ginger and ginger tea.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Ginger might increase the risk of bleeding with warfarin.
Laboratory research suggests that ginger might inhibit thromboxane synthetase and decrease platelet aggregation. In one case report, ginger increased the INR when taken with phenprocoumon, which has similar pharmacological effects as warfarin. In another case report, ginger increased the INR when taken with a combination of warfarin, hydrochlorothiazide, and acetaminophen. A longitudinal analysis suggests that taking ginger increases the risk of bleeding in patients taking warfarin for at least 4 months. However, research in healthy people suggests that ginger has no effect on INR, or the pharmacokinetics or pharmacodynamics of warfarin. Until more is known, monitor INRs closely in patients taking large amounts of ginger.

Likelihood Possible Evidence B
Calcium Channel Blockers

Theoretically, taking ginger with calcium channel blockers might increase the risk of hypotension.
Some animal and in vitro research suggests that ginger has hypotensive and calcium channel-blocking effects. Another animal study shows that concomitant administration of ginger and the calcium channel blocker amlodipine leads to greater reductions in blood pressure when compared with amlodipine alone.

Likelihood Unlikely Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, when taken prior to cyclosporine, ginger might decrease cyclosporine levels.
In an animal model, ginger juice taken 2 hours prior to cyclosporine administration reduced the maximum concentration and area under the curve of cyclosporine by 51% and 40%, respectively. This effect was not observed when ginger juice and cyclosporine were administered at the same time.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, ginger might increase the levels of CYP1A2 substrates.
In vitro research shows that ginger inhibits CYP1A2 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2B6 (Cyp2B6) Substrates

Theoretically, ginger might increase the levels of CYP2B6 substrates.
In vitro research shows that ginger inhibits CYP2B6 activity. However, this interaction has not been reported in humans.

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

Theoretically, ginger might increase the levels of CYP2C9 substrates.
In vitro research shows that ginger inhibits CYP2C9 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Metronidazole (Flagyl)

Theoretically, ginger might increase levels of metronidazole.
In an animal model, ginger increased the absorption and plasma half-life of metronidazole. In addition, the elimination rate and clearance of metronidazole was significantly reduced.

Likelihood Possible Evidence D
organic Ginger [rhizome] juice extract full monograph & interactions

organic 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
organic Reishi full monograph & interactions

organic Shiitake2 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
organic Shiitake full monograph & interactions

organic Maitake3 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
organic Maitake full monograph & interactions

organic 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.

Immuno-Build Mushrooms by Rainbow Light: Common Questions

Does Immuno-Build Mushrooms by Rainbow Light interact with any medications?
Yes. Based on its ingredients, Immuno-Build Mushrooms has a known interaction with 1,262 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Immuno-Build Mushrooms 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.
Is ginger safe during pregnancy?
Ginger is often used for morning sickness, but the data we hold advises caution—check with your doctor first and keep amounts moderate. The other mushroom ingredients (cordyceps, reishi, maitake) don't have enough safety data in pregnancy, so they're best avoided as concentrated supplements.
What are the most common side effects?
Mild digestive symptoms are most common: abdominal discomfort, diarrhea, constipation, nausea, and heartburn. Ginger can cause a pepper-like irritation in your mouth and throat. These usually aren't serious, and some people find that taking the capsules with food reduces symptoms.
Does this product actually work for immune support?
Most of these mushroom ingredients are rated as having insufficient evidence—we don't have enough solid human research yet to say whether they work. Ginger has better evidence, but for nausea, period cramps, and joint pain, not specifically for immunity.
Can I take this if I'm on warfarin or another blood thinner?
No—you need to talk with your pharmacist or doctor first. Ginger, cordyceps, reishi, and maitake all may increase your bleeding risk when combined with blood thinners. A case report documented an unsafe increase in bleeding markers (INR) when someone took ginger with a warfarin-like drug.
What's in here besides the mushrooms and ginger?
The product contains silica and a capsule shell as inactive ingredients—no other fillers are listed.
Is it safe to take this long-term?
Most mushroom ingredients haven't been studied long-term, so we don't have good safety data beyond about a year for cordyceps. Ginger at typical food and supplement amounts is generally well tolerated, but higher doses carry more risk of side effects.
