Lion's mane mushroom explained: what it is, how people take it and what to check first

Lion's mane mushroom is an edible fungus (Hericium erinaceus) that people eat fresh or buy as a powder or capsule. It does not get you high, and research on what it does in the human body is still early and mixed.

This guide covers what the mushroom is, the forms it comes in, what the safety sources report and what to read on a label before you pay. We don't make health claims here. Where research is mentioned, we name who found it and say how strong it is.

What is lion's mane mushroom?

Lion's mane is a tooth fungus. Wikipedia's entry on Hericium erinaceus gives its other names as yamabushitake, bearded tooth fungus and bearded hedgehog. It tends to grow as a single shaggy clump with dangling spines longer than 1 centimetre. The fruit bodies measure 5 to 40 centimetres across. There is no distinct cap and no stipe, just a white mass of crowded, hanging, spore-producing spines.

In East Asian cooking it has a meaty texture and a mild, seafood-like flavour, and it is often sautéed in butter or brewed into tea. As a supplement, most people meet it as a dried powder, a capsule or an ingredient in a blend.

Wikipedia describes it as an edible mushroom used in traditional Chinese medicine. It also says that the mushroom's medicinal effectiveness, its safety in supplements and its active compounds are unproven.

Does lion's mane get you high?

No. Britannica states that lion's mane contains no psilocybin or psilocin, so it does not cause hallucinations or the 'high' of psychedelic mushrooms.

There is a caution about the wider market, though. A CDC report found unlabelled psilocybin or psilocin in four of six bags of 'mushroom nootropic' gummies it tested. The CDC notes that lion's mane, chaga, reishi, cordyceps, maitake and turkey tail are not psychogenic, and warns that products sold as mushroom nootropics might contain undisclosed ingredients. Buy from sellers who print a full ingredient list and can tell you how the product is tested.

What does lion's mane do to your body?

Nobody can give you a firm answer yet, and we won't pretend to.

A 2025 narrative review says in its abstract: 'Despite promising findings, clinical validation remains limited.' It calls for large-scale clinical trials and for standardised extraction methods. The LiverTox entry from the US National Library of Medicine says lion's mane is not approved in the United States to treat symptoms or any disease, and that it has not been through prospective safety trials.

The human trials that do exist are small and point in different directions. WorkMode's science page cites a placebo-controlled trial that found faster Stroop reaction times an hour after a single dose of lion's mane, plus a trend towards lower stress at 28 days. It also cites a 2025 study that found no acute effect on global cognition. The page itself calls the picture 'mixed'.

So the honest summary is that some early findings exist, others found nothing, and the long-term questions are open. If you have a health question, ask a doctor or pharmacist rather than a supplement website.

How people take lion's mane

The mushroom comes in a few forms, and they are not the same thing.

• Cooked fresh. Sautéed in butter or brewed as a tea, as in East Asian cooking. Hard to source in South Africa.
• Dried powder. Stirred into water, coffee or food. Powder from the whole fruiting body is a different product from a concentrated extract.
• Extract capsules. A set amount of extract per capsule, usually taken with a meal. A typical label lists 'Lion's mane fruiting body extract' and directs one capsule daily with meals.
• One ingredient in a blend. Lion's mane sits alongside other actives, so the amount of each matters.

Doses in published trials vary, and extracts and powders are not directly comparable, so we won't suggest a target amount. Follow the directions on the product you buy.

WorkMode ON is a blend of this kind. It is a powder mixed into 250 to 300ml of cold water at breakfast, and each 7g serving contains 200mg of lion's mane extract. Customers take it as directed: two scoops in the morning.

Is lion's mane safe to take every day, and what are the side effects?

No source we found offers a guarantee, and we can't either.

The 2025 narrative review says lion's mane is generally recognised as safe (GRAS) when eaten as a food. It also says long-term human studies are needed to set safe dosage guidelines, and that people with a known mushroom allergy should avoid it. LiverTox, as noted above, says it has not had prospective safety trials.

What has been reported:

• LiverTox says that in clinical trials of prolonged use, mild gastrointestinal complaints (abdominal discomfort, nausea or diarrhoea) were usually reported in less than 10% of people treated.
• LiverTox also describes at least one acute hypersensitivity reaction to oral lion's mane.
• A 2025 review lists stomach discomfort, headache and allergic reactions.
• There is one case report from Japan of acute respiratory distress syndrome after prolonged use. It is a single report, so treat it as rare.

A Restorative Medicine monograph adds that there has been no concerted investigation of lion's mane in pregnancy and lactation.

Practical steps: follow the label, and speak to a pharmacist or doctor first if you are pregnant, breastfeeding, taking medication or unsure. WorkMode's FAQ gives the same advice for its products, including for people sensitive to caffeine.

What to check on the label before you buy

Most lion's mane labels leave out something useful. Read these points before you pay.

Amount per serving. Look for milligrams of lion's mane, not just the total serving size. A 7g scoop of blend and a 7g scoop of pure powder are very different things.

Extract or plain powder. An extract is concentrated. A plain powder is ground mushroom. The label should say which, and ideally the extract ratio.

Fruiting body or mycelium. The mushroom (the fruiting body) and the mycelium, the root-like threads it grows from, contain different compounds. Hideaki Kawagishi, whose lab first described them, reports hericenones from the fruiting body and erinacines from the mycelium, so the two are not interchangeable. We won't pick a winner. Just check which one you are buying.

What else is in it. In a blend, check every active and its dose. If caffeine or other stimulants are listed, factor that in.

SAHPRA wording. SAHPRA says the quality, safety and efficacy of complementary medicines in South Africa cannot be ascertained unless it has evaluated and registered them, and that Category D complementary medicines must meet the labelling regulations (regulation 10). In practice, you will see notices such as: 'This unregistered medicine has not been evaluated by SAHPRA for its quality, safety or intended use.' That notice is worth reading, not skipping. If you want to know the legal status of a particular product, ask SAHPRA or a pharmacist.

Testing. Ask whether a third party tests the product and whether the seller will show a certificate of analysis. This matters more given the CDC findings on undisclosed ingredients.

A stand-alone capsule makes this easy: one ingredient, one dose, one part of the mushroom. A blend asks more of you, because you have to read the whole panel.

Where lion's mane sits in WorkMode ON

WorkMode ON is a morning drink mix. Each 7g serving contains 200mg of lion's mane extract, 250mg of L-theanine and 90mg of caffeine, alongside other ingredients listed in full on the label and on the science page.

The label lists the lion's mane as fruiting body, as 200mg of a 4:1 extract.

Directions: mix 2 scoops (7g) into 250 to 300ml of cold water at breakfast.

WorkMode ON is made by a manufacturer in South Africa, and its label carries a SAHPRA notice.

If you are pregnant, breastfeeding, on medication or sensitive to caffeine, check with a healthcare professional before using it, as the FAQ says. You can see the other morning products in the Focus Better collection.

Questions people ask

Does lion's mane get you high?

No. Britannica says it contains no psilocybin or psilocin and does not cause hallucinations. The CDC has found psilocybin in some 'mushroom nootropic' gummies of unclear origin, so buy products with a full label and testing.

What does lion's mane do to your body?

That is not settled. A 2025 narrative review says clinical validation remains limited, and human trials have given mixed results. For health questions, ask a doctor or pharmacist.

What are the side effects of lion's mane?

LiverTox reports mild stomach complaints (discomfort, nausea, diarrhoea), usually in under 10% of people in longer trials, and at least one acute hypersensitivity reaction. A 2025 review also lists headache and allergic reactions. These are reported effects, not common ones.

Is it safe to take lion's mane daily?

No source guarantees it. The 2025 review calls it generally recognised as safe as a food but says long-term human studies are still needed. Follow the label, and ask a doctor or pharmacist first if you have a mushroom allergy, are pregnant or breastfeeding, or take medication.

Is lion's mane fruiting body or mycelium better?

The sources don't pick a winner. They contain different compounds (hericenones in the fruiting body, erinacines in the mycelium), and mycelium grown on grain can carry starch. Check which part is used and how it is extracted. WorkMode ON uses the fruiting body, as a 4:1 extract.

Is lion's mane legal in South Africa?

We can't give a legal verdict. SAHPRA regulates complementary medicines, labelling rules apply, and some South African lion's mane labels carry an 'unregistered medicine' notice. Check with SAHPRA or a pharmacist about a specific product.
