HelloPharmacist Scorecard of Mushroom D2 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.
What’s inside
Full disclosure
Mushroom D2 contains three active ingredients: shiitake mushroom extract, vitamin D, and agaricus mushroom powder. The product also includes inactive ingredients—hypromellose, microcrystalline cellulose, silicon dioxide, stearic acid, and citric acid—which serve as capsule material, binders, and preservatives.
Vitamin D is included to support bone health and calcium absorption. The two mushroom extracts are traditionally used to support immune function, though the evidence for most of their claimed uses remains limited.
Does it work?
Couldn't assess
Vitamin D is effective for treating rickets, familial hypophosphatemia, osteomalacia (soft bones), renal bone disease, and hypoparathyroidism (low parathyroid hormone). For shiitake mushroom extract, dental plaque prevention is rated possibly ineffective; most other claimed uses—including cancer support and chemotherapy side effect relief—have insufficient evidence to rate.
Agaricus mushroom similarly lacks reliable evidence for the conditions it's marketed for, including allergies, bone health, cancer, and heart disease.
How safe is it?
Well-documented data
Vitamin D is generally well tolerated at recommended doses but can cause toxicity at very high doses over time, with symptoms including high blood calcium levels, bone loss, and vision problems. Shiitake mushroom extract is generally well tolerated when the mushrooms are cooked, but concentrated supplements lack safety data.
Raw shiitake can cause a distinctive skin eruption (shiitake dermatitis), and rarely, intestinal blockage. Handling raw shiitake can trigger allergic contact dermatitis, asthma, or pneumonia in sensitive people.
Agaricus mushroom is generally well tolerated orally, but supplement safety is not well established. Rare serious adverse effects reported include allergic reactions, liver damage (hepatotoxicity), and lung inflammation.
Most common side effects across all three ingredients are abdominal discomfort, diarrhea, nausea, and bloating.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your pharmacist if you take any heart rhythm medications (verapamil, diltiazem, digoxin), thiazide water pills, cholesterol drugs (especially atorvastatin), diabetes medications, immune-suppressing drugs, or psychiatric or pain medications. These carry moderate interactions.
Also mention any aluminum-containing antacids or calcipotriene cream you use.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product is mainly a vitamin D supplement with added mushroom extracts. If you're on heart rhythm medications, water pills, cholesterol drugs, diabetes medications, or immune-suppressing drugs, check with your pharmacist before starting—the interactions are real and can affect how your drugs work.
Vitamin D itself is effective for certain bone and mineral disorders, but the mushroom ingredients lack strong evidence for their claimed uses.

Mushroom D2 by Real Mushrooms Drug Interactions
HelloPharmacist Interaction Report
Real Mushrooms Mushroom D2 contains three active ingredients, and we've found documented interactions with medications across two of them.
The most serious concern involves vitamin D and a range of heart and bone-related drugs. Vitamin D can increase calcium levels in your blood (hypercalcemia), which poses a moderate risk with heart rhythm medications like verapamil, diltiazem, and digoxin—potentially reducing their effectiveness or increasing the risk of dangerous heart rhythms.
The same high-dose vitamin D effect also interacts moderately with thiazide water pills, calcipotriene (a vitamin D–like psoriasis treatment), and aluminum-containing antacids or binders.
Read the full breakdown — every affected drug type, severity by severity
Vitamin D also shows a moderate interaction with atorvastatin (a cholesterol drug), where vitamin D may reduce how well your body absorbs the medication. Additionally, vitamin D may induce a liver enzyme (CYP3A4) that breaks down many common drugs—a minor-severity concern affecting a broad class of medications.
Shiitake mushroom extract carries two moderate interactions: it may theoretically weaken immune-suppressing drugs (used after transplant or for autoimmune conditions), and it might reduce levels of certain psychiatric and pain medications metabolized by the CYP2D6 enzyme. Agaricus mushroom shows a moderate interaction with diabetes drugs, where it might increase the risk of low blood sugar (hypoglycemia).
Altogether, these interactions span 960 individual medications. Please use the search tool on this page to check your exact prescriptions before starting.

For each ingredient in Mushroom D2 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.
Vitamin D
Aluminum
Vitamin D might increase aluminum absorption and toxicity, but this has only been reported in people with renal failure.
The protein that transports calcium across the intestinal wall can also bind and transport aluminum. This protein is stimulated by vitamin D, which may therefore increase aluminum absorption. This mechanism may contribute to increased aluminum levels and toxicity in people with renal failure, when they take vitamin D and aluminum-containing phosphate binders chronically.
Atorvastatin (Lipitor)
Vitamin D might reduce absorption of atorvastatin.
A small, low-quality clinical study shows that taking vitamin D reduces levels of atorvastatin and its active metabolites by up to 55%. However, while atorvastatin levels decreased, total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol levels did not substantially change. Atorvastatin is metabolized in the gut by CYP3A4 enzymes, and researchers theorized that vitamin D might induce CYP3A4, causing reduced levels of atorvastatin. However, this proposed mechanism was not specifically studied.
Calcipotriene (Dovonex)
Taking calcipotriene with vitamin D increases the risk for hypercalcemia.
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia. Theoretically, combining calcipotriene with vitamin D supplements might increase the risk of hypercalcemia.
Digoxin (Lanoxin)
Theoretically, hypercalcemia induced by high-dose vitamin D can increase the risk of arrhythmia from digoxin.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia increases the risk of fatal cardiac arrhythmias with digoxin. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and digoxin concurrently.
Diltiazem (Cardizem, Others)
Theoretically, hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of diltiazem for arrhythmia.
High doses of vitamin D can cause hypercalcemia. Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation. Theoretically this could also occur with diltiazem. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and diltiazem concurrently.
Thiazide Diuretics
Theoretically, taking thiazide diuretics and high-dose vitamin D can increase the risk of hypercalcemia.
Thiazide diuretics decrease urinary calcium excretion, which could lead to hypercalcemia if vitamin D supplements are taken concurrently. This has been reported in people being treated with vitamin D for hypoparathyroidism, and also in elderly people with normal parathyroid function who were taking a thiazide, vitamin D, and calcium-containing antacids daily.
Verapamil (Calan, Others)
Hypercalcemia induced by high-dose vitamin D can reduce the therapeutic effects of verapamil for arrhythmia.
Hypercalcemia due to high doses of vitamin D can reduce the effectiveness of verapamil in atrial fibrillation. Avoid vitamin D doses above the tolerable upper intake level (4000 IU daily for adults) and monitor serum calcium levels in people taking vitamin D and verapamil concurrently.
Cytochrome P450 3A4 (Cyp3A4) Substrates
Vitamin D might induce CYP3A4 enzymes and reduce the bioavailability of CYP3A4 substrates.
There is some concern that vitamin D might induce CYP3A4. In vitro research suggests that vitamin D induces CYP3A4 transcription. Additionally, observational research has found that increased UV light exposure and serum vitamin D levels are associated with decreased serum levels of CYP3A4 substrates such as tacrolimus and sirolimus, while no association between UV light exposure or vitamin D levels and levels of mycophenolic acid, a non-CYP3A4 substrate, was found. A small, low-quality clinical study shows that taking vitamin D reduces levels of the CYP3A4 substrate atorvastatin and its active metabolites by up to 55%; however, the clinical effects of atorvastatin were not reduced. While researchers theorized that vitamin D might induce CYP3A4, this proposed mechanism was not specifically studied.
Shiitake Mushroom Extract
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.
Immunosuppressants
Theoretically, taking shiitake mushroom might decrease the effects of immunosuppressive therapy.
In vitro evidence suggests that shiitake mushroom extracts stimulate immune function.
Agaricus Mushroom, Powder
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.
