HelloPharmacist Scorecard of Lion's Mane Mushroom 500 mg by Swanson

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 Aug 13, 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 Mushroom at 500 mg per capsule. The capsule also holds inactive ingredients — gelatin, rice extract blend, rice flour, and rice concentrate — which are fillers and binding 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 mental health and calm alertness.
  • We looked for evidence on: Anxiety, Cognitive function, Memory, Depression, focus, concentration — and 1 related terms.
  • The closest evidence on file: Lion's Mane Mushroom is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: Lion's Mane Mushroom is rated "Insufficient Reliable Evidence To Rate" for Cognitive function, Depression, Memory.

The evidence isn't established in the data we hold for lion's mane mushroom. The facts list six potential uses — Alzheimer disease, anxiety, athletic performance, cancer, cognitive function, and cognitive impairment — but all are rated as having insufficient reliable evidence to rate.

That means we don't have solid clinical data yet to say whether this supplement works for those purposes.

The evidence, ingredient by ingredient Lion's Mane Mushroom

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, but long-term safety as a supplement hasn't been well studied. The most common side effects reported are gastrointestinal discomfort, nausea, and skin rash.

There isn't enough safety data to recommend it during pregnancy or while breastfeeding — talk with your doctor or pharmacist before using it if you're pregnant, planning to become pregnant, or nursing.

Side effects, ingredient by ingredient 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?
  • 1 of the 1 matched ingredient can interact with medications — 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: 327 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.

Before you start, double-check this product with your doctor or pharmacist if you take blood thinners (anticoagulants or antiplatelet drugs) — lion's mane may raise your bleeding risk. Also check if you're on diabetes medications, since lion's mane may lower blood sugar further, or if you take immunosuppressants, because it may interfere with how well they work.

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 mushroom may be worth considering if you're curious about cognitive or immune support, but the evidence for its effectiveness isn't solid yet. If you take blood thinners, diabetes medications, or drugs that suppress your immune system, you'll need to check with your own doctor or pharmacist first — the interactions are real.

It's generally well tolerated, but side effects like nausea and stomach upset can happen.

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 exactly is Lion's Mane Mushroom?
It's a medicinal mushroom used in traditional medicine. This product delivers 500 mg of it per capsule in a gelatin capsule with rice-based fillers.
Does it actually work for brain health or memory?
The evidence isn't clear yet. The data we hold rates it as having insufficient reliable evidence for cognitive function, cognitive impairment, and Alzheimer disease, among other uses — meaning clinical studies haven't proven it works for these.
What side effects should I watch for?
Most commonly, people report gastrointestinal discomfort, nausea, and skin rash. It's generally well tolerated, but these can happen — stop and talk to your pharmacist if any bother you.
Is it safe if I'm pregnant or breastfeeding?
There isn't enough safety data, so it's best to avoid it during pregnancy and while breastfeeding. Talk with your doctor or pharmacist for personalized advice if you're in either situation.
Can I take this with my blood thinner?
That depends on your specific medication and health. Lab research suggests lion's mane may increase bleeding risk, so check with your own doctor or pharmacist before combining them.
What if I'm diabetic — can I add this to my medication?
Animal research suggests lion's mane can lower blood sugar, so it might add to your diabetes drug's effect. You'll want to clear this with your doctor or pharmacist before starting.
