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 Sporocarp Extract. It's just the mushroom extract itself with no other active components.

There are no inactive fillers listed for this powder.

Does it work?

Couldn't assess
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 assessable

This is a single-ingredient Lion's Mane Mushroom product and its label doesn't state a use — see Lion's Mane Mushroom's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for lion's mane mushroom isn't established enough in our data to rate it for any use. We hold insufficient reliable evidence to say whether it helps with Alzheimer disease, anxiety, athletic performance, cancer, cognitive function, or cognitive impairment.

That doesn't mean it doesn't work—it means the research we have access to hasn't met the bar to make a confident claim yet.

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. When taken as a supplement, most people tolerate it without problems, though a small number of people in trials reported gastrointestinal discomfort, nausea, or skin rash.

Long-term supplement safety hasn't been well studied. Because there isn't enough safety data, the evidence advises against use during pregnancy and while breastfeeding—talk with your doctor or pharmacist for personalized guidance if you're pregnant, planning pregnancy, or nursing.

Lion's mane mushroom is generally well tolerated orally, but solid evidence for what it does is lacking. If you take blood thinners, diabetes medications, or immunosuppressants, check with us or your pharmacist first—this supplement may affect how they work.

How can one product interact with so many drugs?
Lion's Mane Mushroom 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.
Can I take lion's mane mushroom if I'm pregnant or breastfeeding?
There isn't enough safety data to know. The evidence advises against it during pregnancy and while breastfeeding. Talk with your doctor or pharmacist about your individual situation.
What side effects should I watch for?
Most people tolerate it well. A small number report gastrointestinal discomfort, nausea, or skin rash. Stop and call your pharmacist or doctor if you have any of these.
Does lion's mane mushroom actually work for memory or brain health?
We don't have reliable evidence yet to say whether it helps with memory, cognitive function, Alzheimer disease, or other brain conditions. The research isn't strong enough to make a claim.
Why is long-term safety not well studied?
Lion's mane has been eaten as food for a long time, but it hasn't been tested as a supplement for long periods in rigorous studies. That's why we know less about what happens if you take it daily for months or years.
Is this powder safe to take with food or on an empty stomach?
The product facts don't specify. Ask your pharmacist about the best way to take it for your situation.
