HelloPharmacist Scorecard of Lion's Mane by ProCaps

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.

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 Powder. It's a medicinal mushroom that's been used traditionally to support brain health and cognitive function, though the evidence for those uses isn't well established yet.

The capsule itself contains cellulose, a standard plant-based 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 — see Lion's Mane Mushroom's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Memory and cognitive support.
  • We looked for evidence on: Alzheimer disease, Cognitive function, Cognitive impairment, Dementia, Memory, Parkinson 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 Cognitive function, Cognitive impairment, Dementia, Memory, and more.

The evidence for lion's mane isn't solid enough for us to rate it. The data we hold shows insufficient reliable evidence for Alzheimer disease, anxiety, athletic performance, cancer, cognitive function, and cognitive impairment.

That doesn't mean it doesn't work — it means larger, better-designed studies haven't been done yet to prove it does.

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.

Lion's mane is generally well tolerated when eaten as food, but long-term supplement safety hasn't been studied thoroughly. The most common side effects people report are gastrointestinal discomfort, nausea, and skin rash.

The safety data advises against use during pregnancy and while breastfeeding — there simply isn't enough information to know it's safe in those situations.

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 is worth considering if you're interested in brain health support and don't take blood thinners, diabetes medication, or immunosuppressants. If you're on any of those, talk to your pharmacist before adding this.

Pregnant or breastfeeding? Skip it until you've discussed it with your doctor.

Formula

Hericium erinaceus

Our Lion's Mane provides a pure source of organic Hericium erinaceus mushroom typically consumed by those seeking to promote brain and nervous system health. Our Lion's Mane is an organic full-spectrum blend of both above-ground fruiting bodies, along with below-ground mycelium. Mushrooms are incredibly unique. There are truly no other living things like them. They are neither animal nor plant but separately classified as fungi. They have been an important part of the human diet since prehistoric times and have been used in traditional medicine for thousands of years. Lion's Mane mushrooms are large, white, shaggy mushrooms that resemble a lion's mane and have long been recognized for a variety of health benefits, particularly to the brain and nervous system. In fact, Lion's Mane has often been referred to as "Nature's nutrient for the neurons (nerve cells)." Lion's Mane has been the subject of scientific research relating to its support of brain and nervous system health, along with positive mood and cognition. If you seek what experts consider to be the premier mushroom for brain and nervous system support, then look no further than our organic, full-spectrum Lion's Mane mushroom blend.

Does Lion's Mane by ProCaps interact with any medications?
Yes. Based on its ingredients, Lion's Mane 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 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 this if I'm on blood thinners like warfarin?
You shouldn't without talking to your pharmacist first. Lion's mane may increase bleeding risk when combined with blood thinners or antiplatelet drugs. This is a Moderate severity interaction, so it matters.
What side effects should I watch for?
The most common are stomach discomfort, nausea, and skin rash. Most people tolerate it well, but if you develop a rash or persistent nausea, stop and let your pharmacist know.
Can I take this while pregnant or breastfeeding?
The safety data advises against it — there isn't enough information to know either way. Talk with your doctor or pharmacist about what's right for you in those situations.
Will this help my brain fog or memory?
Lion's mane is traditionally used for brain health, but the evidence isn't strong enough yet to say it works. We don't have reliable proof for cognitive function, cognitive impairment, Alzheimer disease, or anxiety.
Is there anything else in these capsules besides the mushroom?
Just cellulose, a plant-based filler that helps make the capsule. No other active ingredients.
