HelloPharmacist Scorecard of Lion's Mane by New Sun

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.
  • No proprietary blends here — you can verify the dose of every single component.

New Sun's Lion's Mane is a single-ingredient supplement: one active ingredient, lion's mane mushroom, in a vegetarian capsule. The capsule itself is an inactive ingredient that simply holds the mushroom powder or extract.

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: mental support.
  • We looked for evidence on: Anxiety, Cognitive function, Cognitive impairment, Memory, Depression, focus — and 2 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, Cognitive impairment, Depression, Memory.

The evidence for lion's mane's effectiveness isn't established in the data we hold. The product is marketed for cognitive function, Alzheimer disease, anxiety, athletic performance, cancer, and cognitive impairment, but the facts we have show insufficient reliable evidence to rate it for any of these uses.

That doesn't mean it doesn't work — it means rigorous research is still missing or inconclusive.

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 a food, though long-term safety as a supplement hasn't been thoroughly studied. The most commonly reported side effects from oral use are gastrointestinal discomfort, nausea, and skin rash.

The safety data advises against use during pregnancy and while breastfeeding due to insufficient information.

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 taking this Lion's Mane, double-check it with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel) — there's a Moderate risk of increased bleeding. Also flag diabetes medications and any immunosuppressants (used after transplant or for certain autoimmune conditions), as lion's mane may interfere with how these 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 may be worth considering if you're interested in cognitive or immune support, but the evidence for its benefits isn't solid yet. If you take blood thinners, diabetes medications, or immune-suppressing drugs, you'll want to check with your doctor or pharmacist before starting it.

Discuss whether it's right for you and your medications with your own healthcare provider.

Lion's Mane by New Sun: Common Questions

Does Lion's Mane by New Sun 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 Lion's Mane while pregnant or breastfeeding?
No. The safety data isn't there to recommend it during pregnancy or while breastfeeding. Talk with your doctor or pharmacist about whether it's right for you in these situations.
What side effects might I experience?
Most commonly, gastrointestinal discomfort, nausea, and skin rash. Lion's mane is generally well tolerated overall, but long-term safety as a supplement hasn't been well studied.
Does Lion's Mane actually improve memory and focus?
The evidence isn't established yet. While lion's mane is marketed for cognitive function and brain health, we don't have reliable data showing whether it really works for these uses.
Why is this a Moderate interaction with blood thinners?
Lab research suggests lion's mane can interfere with platelet clumping, which is how your blood clots. If you're already on a blood thinner, adding that effect could raise your bleeding risk.
What's in the capsule besides the mushroom?
Just the vegetarian capsule itself — a plant-based shell that holds the lion's mane. There are no added fillers or binders.
