HelloPharmacist Scorecard of Peak Power Mushroom Complex by Fresh Healthcare

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

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 7 active ingredients.
  • “Peak O2 Proprietary Blend of 6 Mushrooms” is a proprietary blend — the label gives one combined amount (1,800 mg) without saying how much of each component you get.

Peak Power Mushroom Complex contains 7 ingredients total. The active components are reishi powder, black pepper powder, a proprietary blend of 6 mushrooms called Peak O2 (cordyceps, king trumpet, shiitake, and lion's mane are named separately below that blend), cordyceps powder, king trumpet powder, shiitake powder, and lion's mane powder.

The product also contains two inactive ingredients: hydroxypropyl methylcellulose (a capsule material) and organic rice concentrate (a filler).

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: brain health and immune function support.
  • We looked for evidence on: Cognitive function, Memory, Dementia, Alzheimer disease, Anxiety, Fatigue — and 4 related terms.
  • The closest evidence on file: Cordyceps is rated "Possibly Ineffective" for Athletic performance (Natural Medicines).
  • Also on file: Cordyceps is rated "Insufficient Reliable Evidence To Rate" for Fatigue.
  • Also on file: Shiitake Mushroom is rated "Insufficient Reliable Evidence To Rate" for Common cold, Influenza.

The evidence for what these mushrooms and black pepper can accomplish is limited or hasn't been established in the data we hold. Reishi is rated possibly ineffective for high cholesterol, and there isn't enough reliable evidence to rate it for altitude sickness, Alzheimer's disease, or athletic performance.

Black pepper, cordyceps, shiitake, and lion's mane all lack sufficient evidence to rate them for the conditions they're marketed for — which include sexual function, lung health, immune support, and cognitive function. None of these ingredients have a strong evidence rating for any condition in our data.

The evidence, ingredient by ingredient Black Pepper Reishi Mushroom Cordyceps Shiitake Mushroom Lion's Mane Mushroom

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 4 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.

Reishi, cordyceps, shiitake, and lion's mane are generally well tolerated when taken short-term, though long-term safety hasn't been well studied. The most common side effects are digestive — nausea, stomach upset, diarrhea, and abdominal discomfort — plus dizziness and dry mouth with reishi.

Black pepper is generally safe at food-spice levels, but concentrated supplements should be used cautiously; common effects are burning aftertaste and indigestion. Raw shiitake mushrooms can cause a distinctive skin reaction called shiitake dermatitis.

All five ingredients with safety data recommend avoiding them during pregnancy and breastfeeding due to lack of safety data. King Trumpet and turkey tail safety data isn'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?
  • 5 of the 5 matched ingredients can interact with medications — Cordyceps, Shiitake Mushroom, Black Pepper, Reishi Mushroom, Lion's Mane Mushroom.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; lithium.
  • For scale: 1,228 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.

Check with your doctor or pharmacist before using this product if you take blood pressure medications, blood thinners (anticoagulants or antiplatelets), diabetes drugs, propranolol, nevirapine, rifampin, phenytoin, cyclosporine, pentobarbital, atorvastatin, theophylline, CYP2D6 substrate drugs, or immune-suppressing medications. These are all documented interactions (Moderate severity) with ingredients in this blend.

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 is a mushroom blend with black pepper, mostly used for immune and energy support — but evidence for those claims is thin. If you take blood pressure meds, diabetes drugs, blood thinners, or any of the specific medications black pepper interacts with, you'll need to check with your own doctor or pharmacist before starting.

Anyone pregnant, breastfeeding, or on immunosuppressant therapy should talk it over with their healthcare provider first.

For each ingredient in Peak Power Mushroom Complex 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.

Black Pepper powder17 drug types · 1,019 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, black pepper might increase the risk of bleeding when taken with antiplatelet or anticoagulant drugs.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit platelet aggregation. This has not been reported in humans.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, black pepper might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that piperine, a constituent of black pepper, can reduce blood glucose levels. Monitor blood glucose levels closely. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Atorvastatin (Lipitor)

Theoretically, black pepper might increase blood levels of atorvastatin.
Animal research shows that taking piperine, a constituent of black pepper, 35 mg/kg can increase the maximum serum concentration of atorvastatin three-fold. This has not been reported in humans.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, black pepper might increase the effects and side effects of cyclosporine.
In vitro research shows that piperine, a constituent of black pepper, increases the bioavailability of cyclosporine. This has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, black pepper might increase levels of drugs metabolized by CYP2D6.
In vitro research suggests that some constituents of black pepper inhibit CYP2D6. This has not been reported in humans.

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

Theoretically, black pepper might increase levels of drugs metabolized by CYP3A4.
In vitro research and pharmacokinetic simulation data suggest that piperine, a constituent of black pepper, as well as the pepper fruit seem to inhibit CYP3A4. This has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, black pepper might increase blood levels of lithium due to its diuretic effects. The dose of lithium might need to be reduced.
Black pepper is thought to have diuretic properties.

Likelihood Probable Evidence D
Nevirapine (Viramune)

Black pepper might increase blood levels of nevirapine.
Clinical research shows that piperine, a constituent of black pepper, increases the plasma concentration of nevirapine. However, no adverse effects were observed in this study.

Likelihood Probable Evidence D
P-Glycoprotein Substrates

Theoretically, black pepper might increase levels of P-glycoprotein substrates.
In vitro research shows that piperine, a constituent of black pepper, seems to inhibit P-glycoprotein.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, black pepper might increase the sedative effects of pentobarbital.
Animal research shows that piperine, a constituent of black pepper, increases pentobarbital-induced sleeping time.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Black pepper might increase blood levels of phenytoin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption, slow elimination, and increase levels of phenytoin. Taking a single dose of black pepper 1 gram along with phenytoin seems to double the serum concentration of phenytoin. Consuming a soup with black pepper providing piperine 44 mg/200 mL of soup along with phenytoin also seems to increase phenytoin levels when compared with consuming the same soup without black pepper.

Likelihood Possible Evidence B
Propranolol (Inderal)

Black pepper might increase blood levels of propranolol.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of propranolol.

Likelihood Possible Evidence B
Rifampin (Rifadin)

Black pepper might increase blood levels of rifampin.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and serum levels of rifampin.

Likelihood Possible Evidence B
Theophylline

Black pepper might increase blood levels of theophylline.
Clinical research shows that piperine, a constituent of black pepper, seems to increase absorption and slow elimination of theophylline.

Likelihood Possible Evidence D
Amoxicillin (Amoxil, Trimox)

Theoretically, black pepper might increase the effects and side effects of amoxicillin.
Animal research shows that taking piperine, a constituent of black pepper, with amoxicillin increases plasma levels of amoxicillin. This has not been reported in humans.

Likelihood Possible Evidence D
Carbamazepine (Tegretol)

Theoretically, black pepper might increase blood levels of carbamazepine, potentially increasing the effects and side effects of carbamazepine.
One clinical study in patients taking carbamazepine 300 mg or 500 mg twice daily shows that taking a single 20 mg dose of purified piperine, a constituent of black pepper, increases carbamazepine levels. Piperine may increase carbamazepine absorption by increasing blood flow to the GI tract, increasing the surface area of the small intestine, or inhibiting cytochrome P450 3A4 (CYP3A4) in the gut wall. Absorption was significantly increased by 7-10 mcg/mL/hour. The time to eliminate carbamazepine was also increased by 4-8 hours. Although carbamazepine levels were increased, this did not appear to increase side effects. In vitro research also shows that piperine can increase carbamazepine levels by 11% in a time-dependent manner.

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

Theoretically, black pepper might decrease levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that black pepper induces CYP1A2. This has not been reported in humans.

Likelihood Possible Evidence D
Black Pepper powder full monograph & interactions

Reishi powder3 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 powder full monograph & interactions

Lion's Mane powder3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, lion's mane mushroom may increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.
In vitro research suggests that lion's mane mushroom extracts can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, lion's mane mushroom may have additive effects when used with antidiabetes drugs.
Animal research suggests that an aqueous extract of lion's mane mushroom can reduce serum glucose and increase serum insulin.

Likelihood Possible Evidence D
Immunosuppressants

Theoretically, concurrent use of lion's mane mushroom might interfere with immunosuppressive therapy.
In animal and in vitro research, lion's mane mushroom polysaccharides stimulate the immune system.

Likelihood Possible Evidence D
Lion's Mane powder full monograph & interactions

Shiitake powder2 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 powder full monograph & interactions

Cordyceps powder3 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.

Peak Power Mushroom Complex by Fresh Healthcare: Common Questions

Does Peak Power Mushroom Complex by Fresh Healthcare interact with any medications?
Yes. Based on its ingredients, Peak Power Mushroom Complex has a known interaction with 1,227 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Peak Power Mushroom Complex contains 7 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 while pregnant or breastfeeding?
The safety data advises against it. Reishi, cordyceps, shiitake, and lion's mane all lack enough safety information during pregnancy and lactation. Talk with your doctor or pharmacist about whether this product is right for you.
What are the most common side effects?
Digestive upset — nausea, diarrhea, stomach discomfort — is most frequent. You might also notice dizziness, dry mouth, or a burning aftertaste from the black pepper. Most people tolerate it well short-term.
Does this actually boost energy or immune function?
The evidence isn't established in our data. Cordyceps and shiitake are often marketed for energy and immunity, but there isn't enough reliable evidence to rate them for those purposes yet.
Is there anything in this besides the mushrooms?
Yes — black pepper powder is an active ingredient, and the capsule contains hydroxypropyl methylcellulose and organic rice concentrate as inactive ingredients.
What if I'm taking immunosuppressant drugs?
Cordyceps, shiitake, and lion's mane all carry theoretical risks of interfering with immune-suppressing medications. Your doctor or pharmacist needs to weigh whether this product is safe for you.
