HelloPharmacist Scorecard of Lion's Mane Mushroom by Gaia Herbs

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

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.
  • “organic Lion's Mane (Hericium erinaceus) fruiting body extract” is listed as a grouped ingredient — the label gives one combined amount (450 mg) without saying how much of each component you get.

This product has one active ingredient: beta-glucans extracted from organic Lion's Mane (Hericium erinaceus) fruiting body. Beta-glucans are naturally occurring carbohydrates found in mushrooms and other foods; they're studied for their effects on cholesterol, heart health, and immune function.

The capsule itself is vegan.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Brain and nerve support.
  • We looked for evidence on: Memory, Cognitive function, Cognitive impairment, Anxiety, Dementia, Alzheimer disease — and 4 related terms.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

Beta-glucans in this product are rated Likely Effective for dyslipidemia (high cholesterol) and coronary heart disease. The evidence we hold doesn't establish effectiveness for other uses of Lion's Mane mushroom itself — that data isn't available to us.

The evidence, ingredient by ingredient Lion's Mane Mushroom Beta-glucans

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 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.

Beta-glucans from food are generally well tolerated. Concentrated supplements like this one lack the safety data that whole foods have, so use caution.

In rare cases, oral beta-glucans at very high doses have caused temporary liver enzyme elevation in at least one person. There isn't enough research on supplement doses during breastfeeding to know either way — talk with your doctor or pharmacist for personalized advice if you're nursing.

Pregnancy safety data is not on file for this ingredient.

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 — Beta-glucans.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 293 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 before taking this product if you're on blood pressure medication (antihypertensives) or immune-suppressing drugs (immunosuppressants) — both could be affected at Moderate severity.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help with cholesterol and heart health if the research on beta-glucans applies to you. But if you take blood pressure medication or an immune-suppressing drug, you'll want to check your exact medications first and clear it with your doctor or pharmacist before you start.
