HelloPharmacist Scorecard of Shiitake Mushroom Extract by BulkSupplements.com
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
This supplement contains one active ingredient: shiitake mushroom fruiting body extract. That's the fleshy, above-ground part of the shiitake mushroom, concentrated into powder form.
There are no other active ingredients—the product is just the extract itself with no inactive fillers or binders listed.
Does it work?
Couldn't assess
The evidence for shiitake mushroom extract is very limited in the areas studied. For dental plaque, it's rated possibly ineffective.
For chemotherapy-induced anemia, breast cancer, cancer in general, and chemotherapy-related nausea and vomiting, there isn't enough reliable evidence to rate how well it works. The data we have doesn't support claims about what this extract can do.
How safe is it?
Well-documented data
When you eat shiitake mushrooms as cooked food, they're generally well tolerated. As a concentrated supplement, though, the safety data is thin, so caution is advised.
Cooked shiitake can cause stomach discomfort, bloating, diarrhea, nausea, or vomiting in some people. Raw shiitake is riskier—it can cause shiitake dermatitis, a distinctive skin eruption that may come with body-wide symptoms.
Rarely, large pieces that aren't chewed well can block the intestines. People who handle or grow shiitake mushrooms extensively may develop allergic contact dermatitis or inhale spores that trigger hypersensitivity pneumonitis (breathing problems, chest pain, dry cough).
We hold no data on safety during pregnancy or breastfeeding—talk with your doctor or pharmacist before using this product if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before you take this, double-check if you're on any immunosuppressant medications (used after transplants or for autoimmune conditions) or any drugs your pharmacist says are processed by the CYP2D6 liver enzyme—both interactions are Moderate. Use the search tool on this page to confirm your exact medications, or ask your pharmacist directly.
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.
Shiitake mushroom extract has only one active ingredient and no evidence of being effective for the conditions studied. It interacts with immunosuppressants and certain liver-processed drugs, both at Moderate severity.
If you take an immunosuppressant or any CYP2D6 substrate medication, check with your own pharmacist or doctor before starting. Because safety data on supplement doses is limited, discuss this with your healthcare provider first.

Shiitake Mushroom Fruiting Body Extract monograph & interactionsShiitake Mushroom Extract by BulkSupplements.com Drug Interactions
HelloPharmacist Interaction Report
Shiitake Mushroom Extract by BulkSupplements.com does interact with medications.
The extract's compounds may interfere with two important drug categories: immunosuppressants and a group of medications processed by a liver enzyme called CYP2D6. Both interactions are rated Moderate in severity.
Read the full breakdown — every affected drug type, severity by severity
With immunosuppressants (drugs that deliberately lower immune function), shiitake mushroom theoretically works against them—it appears to stimulate immunity, which could reduce how well these medications work. With CYP2D6 substrate drugs, the extract may speed up how your liver processes them, potentially lowering their levels in your bloodstream.
This effect has been seen in lab studies but not yet confirmed in people.
Altogether, these interactions span 312 individual medications. Before you start this supplement, check your exact medications—especially any immunosuppressant or any drug your doctor or pharmacist says is processed through CYP2D6—with the search tool on this page or talk it over with your own pharmacist.
