HelloPharmacist Scorecard of Lion's Mane Mushroom 500 mg by Pure Nootropics

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: Lion's Mane Extract, a mushroom-derived compound. The capsule itself is made with hypromellose and stearate, which are inactive binders and capsule materials.

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 — see Lion's Mane Mushroom's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Supports overall mood and cognitive health.
  • We looked for evidence on: Cognitive function, Memory, Anxiety, Depression, Dementia, Alzheimer disease — and 4 related terms.
  • The closest evidence on file: Lion's Mane Mushroom is rated "Insufficient Reliable Evidence To Rate" for Alzheimer disease (Natural Medicines).
  • Also on file: Lion's Mane Mushroom is rated "Insufficient Reliable Evidence To Rate" for Anxiety, Cognitive function, Cognitive impairment, Dementia, and more.

The evidence for lion's mane mushroom is still unsettled. Our data shows insufficient reliable evidence to rate it for Alzheimer's disease, anxiety, athletic performance, cancer, cognitive function, or cognitive impairment.

That doesn't mean it doesn't work — it means the research to date hasn't been strong enough to make a solid claim either way.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 0 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Orally, lion's mane mushroom is generally well tolerated as a food. The most common side effects reported are gastrointestinal discomfort, nausea, and skin rash.

Long-term supplement safety hasn't been well studied yet. Avoid it during pregnancy and breastfeeding — there isn't enough safety data to know whether it's safe for you or your baby.

We don't have information on how common these side effects are from clinical trials, so talk with your pharmacist or doctor if you experience any of them.

  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and some safety-information gaps remain.

Lion's mane may interest you if you're exploring supplements for cognitive health, but the evidence isn't established yet. If you take blood thinners, diabetes medications, or immunosuppressants, check with your pharmacist first — this product could interact with them.

Lion's Mane Mushroom 500 mg by Pure Nootropics: Common Questions

Does Lion's Mane Mushroom 500 mg by Pure Nootropics interact with any medications?
Yes. Based on its ingredients, Lion's Mane Mushroom 500 mg has a known interaction with 327 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lion's Mane Mushroom 500 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What is lion's mane extract and what's it supposed to do?
Lion's mane is an extract from a mushroom traditionally used in Asian cuisine. People take it hoping to support cognitive health, memory, and mood — but our data shows the evidence isn't solid enough to confirm those benefits yet.
Can I take this if I'm pregnant or nursing?
No. There isn't enough safety data, so it's best to avoid lion's mane during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about your options.
What side effects might I experience?
Most common are gastrointestinal discomfort, nausea, and skin rash. Lion's mane is generally well tolerated, but long-term supplement safety hasn't been studied closely.
Is lion's mane proven to help with memory or brain function?
Not yet. We hold insufficient reliable evidence to rate it for cognitive function, cognitive impairment, Alzheimer's disease, anxiety, or other brain-related conditions. More research is needed.
Can I take this with my blood thinner?
That depends on which blood thinner you take and your specific situation — it's a conversation to have with your pharmacist or doctor. Lab research suggests lion's mane may slow clotting, which could raise bleeding risk when combined with these drugs.
