HelloPharmacist Scorecard of AHCC 500 mg by Planetary Herbals
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
Low disclosure
This 5-ingredient capsule is built around shiitake mycelia extract (the root structure of the shiitake mushroom), which is the active component. The other four ingredients — microcrystalline cellulose, dextrin, carnauba wax, and alpha-cyclodextrin — are inactive fillers or binders that help hold the capsule together.
The capsule itself is made of gelatin and magnesium stearate.
Does it work?
Not established
The evidence on shiitake for most health goals is thin. For dental plaque, it's rated possibly ineffective.
For cancer, cancer-related anemia, nausea from chemotherapy, and atherosclerosis, the evidence simply isn't established well enough to say whether it works — these are all rated insufficient reliable evidence. If you're considering this supplement for one of these uses, talk to your doctor about what the current science actually supports.
How safe is it?
Well-documented data
When shiitake is cooked and eaten as food, it's generally well tolerated. As a concentrated supplement at higher doses, the safety data is sparse, so caution is advised.
The most common side effects from oral shiitake are abdominal discomfort, bloating, diarrhea, nausea, and vomiting. Raw shiitake can cause a distinctive skin reaction called shiitake dermatitis (whiplash-like marks) and rarely intestinal blockage if swallowed in large unchewed pieces.
People who handle fresh shiitake extensively can develop allergic contact dermatitis and, in rare cases, breathing problems from spore inhalation. We have no pregnancy or lactation data on file for this ingredient.
Meds to double-check
Moderate interaction found
Check before taking this product if you use immunosuppressant medications (to prevent organ rejection or treat autoimmune disease) or drugs metabolized by the CYP2D6 enzyme, including certain antidepressants and heart medications — both carry moderate interaction risk with shiitake. No interactions are documented in our data for the other three ingredients we could check.
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 supplement may appeal to people interested in immune support, but the evidence for most claimed benefits is weak or absent. If you take immunosuppressants or medications processed by your liver's CYP2D6 pathway, check with your pharmacist before starting — the interaction risk is real in theory, even if not confirmed in humans.
For most others, the main concern is GI upset and the lack of safety data at supplement doses.

Formula
AHCC is a proprietary compound produced by cultivation of shiitake mushroom mycelia, grown in rice bran extract. Considered a superfood supplement in Japan, AHCC has been researched extensively for its immune enhancement properties. Preliminary research indicates that AHCC may significantly increase Natural Killer (NK) Cell activity. There is also evidence to suggest that AHCC may increase macrophage activity, enhance cytokine production, and support the healthy functioning of the liver as well as act as an antioxidant.

AHCC 500 mg by Planetary Herbals Drug Interactions
HelloPharmacist Interaction Report
AHCC 500 mg by Planetary Herbals contains shiitake mycelia extract, which has documented interactions with two drug categories.
The most serious concern is immunosuppressant medications (those that dampen your immune system after transplant or for autoimmune conditions). In theory, shiitake may reduce how well these drugs work, since the extract appears to stimulate immune function in lab studies — though this hasn't been confirmed in people taking the supplement.
Read the full breakdown — every affected drug type, severity by severity
Shiitake may also affect how your body processes certain psychiatric and cardiac medications metabolized by the CYP2D6 enzyme (a liver pathway). Lab evidence suggests the extract might speed up clearance of these drugs, potentially lowering their levels, but again this effect hasn't been observed in humans.
We couldn't check three other ingredients in this product: microcrystalline cellulose, dextrin, and carnauba wax — we hold no interaction data for them. Altogether, these interactions span 308 individual medications.
