HelloPharmacist Scorecard of Fit by Om Mushroom Superfood

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 0 of its 4 active ingredients.
  • “Certified Organic Mushroom Powder Blend” is a proprietary blend — the label gives one combined amount (2 Gram(s)) without saying how much of each component you get.

This powder contains four active ingredients: a certified organic mushroom blend broken down into its individual components—reishi, cordyceps, and lion's mane—each in powder form. The product also contains myceliated oats as an inactive ingredient (a carrier base).

Each of these mushrooms has different traditional roles. Cordyceps and lion's mane are the ones we have interaction data for; reishi is present but we don't hold safety or interaction information on file for it.

Does it work?

Leans against
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
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: supports training energy performance.
  • We looked for evidence on: Athletic performance, Fatigue, Cognitive function, endurance, stamina, exercise capacity.
  • 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: Lion's Mane Mushroom is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Cognitive function.

The evidence on what this product actually does is limited. Cordyceps is rated possibly ineffective for athletic performance; for sexual dysfunction, arrhythmia, asthma, lung cancer, and chronic obstructive pulmonary disease (COPD), there isn't enough reliable evidence to rate it.

Lion's mane similarly lacks enough reliable evidence for Alzheimer disease, anxiety, athletic performance, cancer, and cognitive function or impairment. We don't have effectiveness data on file for reishi.

The evidence, ingredient by ingredient Cordyceps 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 1 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Cordyceps and lion's mane are both generally well tolerated short-term, though the evidence is limited and mushroom supplement quality varies widely. The most common side effects from cordyceps are abdominal discomfort, constipation, and diarrhea—usually uncommon, and sometimes reduced by taking it with food.

Lion's mane may cause gastrointestinal discomfort, nausea, or skin rash. There's one case report of liver inflammation (hepatitis) possibly linked to cordyceps, though it's unclear whether cordyceps or a contaminant was responsible.

Because there isn't enough safety data, cordyceps and lion's mane are advised against during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about whether this product is right for you.

Side effects, ingredient by ingredient Cordyceps Lion's Mane Mushroom

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?
  • 2 of the 2 matched ingredients can interact with medications — Cordyceps, 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.
  • For scale: 335 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 taking this product if you're on blood thinners or antiplatelet drugs (warfarin, apixaban, aspirin, clopidogrel, and others)—cordyceps and lion's mane may increase bleeding risk. If you take immunosuppressants (such as cyclosporine or tacrolimus), diabetes medications, or testosterone therapy, ask your healthcare provider whether it's safe to combine them with this product.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Om Mushroom Superfood Fit is a mushroom blend meant for general wellness, but the evidence that it actually does what people hope for isn't strong. More importantly, if you take blood thinners, diabetes medications, immune-suppressing drugs, or testosterone therapy, you need to clear this with your doctor or pharmacist first—there are documented interactions.

Pregnant or nursing? Skip it, because the safety data isn't there.

Lion's Mane, 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.

Yes. Based on its ingredients, Fit has a known interaction with 335 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Fit contains 4 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 if I'm pregnant or breastfeeding?
No. There isn't enough safety data for cordyceps and lion's mane during pregnancy or breastfeeding, so the data advises against it. Talk with your doctor or pharmacist before considering it.

Does this actually improve athletic performance or brain function?
The evidence doesn't support it. Cordyceps is rated possibly ineffective for athletic performance. For lion's mane and cognitive function, anxiety, and other uses, there simply isn't enough reliable evidence to say whether it works.
What's in this product?
Four active mushroom ingredients—reishi, cordyceps, and lion's mane powders, plus an organic mushroom blend. It also contains myceliated oats as a carrier base.
Why do I need to check my medications before taking this?
