Lion’s mane is legal to buy, sell, and consume in the United States and most other countries. It is not a controlled substance, contains no psychoactive compounds, and is widely sold as a dietary supplement and food ingredient. That said, a few countries treat it differently, and the rules around how it can be marketed vary quite a bit depending on where you live.
Lion’s Mane Is Not a Controlled Substance
The most common reason people search this question is confusion between lion’s mane and psychedelic “magic” mushrooms. The two are completely unrelated. Psilocybin mushrooms contain compounds that cause hallucinations and are classified as Schedule I controlled substances by the U.S. Drug Enforcement Administration. Lion’s mane (Hericium erinaceus) contains none of these compounds. It is a culinary and medicinal mushroom with no psychoactive effects, and it does not appear on any DEA schedule.
Legal Status in the United States
In the U.S., lion’s mane is sold as a dietary supplement under the framework established by the Dietary Supplement Health and Education Act of 1994 (DSHEA). This means the FDA does not review lion’s mane products for safety or effectiveness before they hit shelves, just as it doesn’t for most vitamins or herbal supplements. Manufacturers are responsible for ensuring their products are safe, and they must include a standard disclaimer on any health-related claims: “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.”
You can freely purchase lion’s mane as capsules, powders, tinctures, or whole dried mushrooms from supplement retailers, health food stores, and online shops. Fresh lion’s mane is also sold at farmers’ markets and grocery stores as a culinary ingredient. There are no state-level bans on the mushroom.
Legal Status in the European Union
Lion’s mane is legal throughout the EU. The European Commission confirmed in a February 2025 consultation that the fruiting body of Hericium erinaceus “has been used for human consumption to a significant degree within the Union before 15 May 1997,” which is the cutoff date for the EU’s Novel Food regulations. Because it was already in use before that date, it is classified as “not novel” and does not require special authorization to sell. Extracts made from the fruiting body using standard production methods like ultrasound-assisted extraction also fall outside the novel food category.
One important restriction applies across the EU: sellers cannot make health claims about lion’s mane that haven’t been authorized on the EU’s official register. At the time of writing, no health claims specific to mushrooms themselves have been approved, so marketers can only reference authorized claims for individual nutrients found within the mushroom (like certain B vitamins), not the mushroom as a whole.
Legal Status in the United Kingdom
The UK situation is more complicated. After Brexit, the UK’s Food Standards Agency (FSA) operates its own novel food framework, separate from the EU’s. The UK’s Advertising Standards Authority has flagged that certain functional mushrooms, including turkey tail and some cordyceps species, are likely considered unauthorized novel foods that should not be sold without FSA authorization. Lion’s mane was not specifically named in that same category, but the ASA advises marketers of any newer mushroom product to confirm they have the necessary authorization before selling.
As in the EU, making medicinal claims about lion’s mane (saying it treats, prevents, or cures a disease) is prohibited in the UK unless the product is licensed as a medicine by the Medicines and Healthcare products Regulatory Agency. Health and nutrition claims on food products must also be individually authorized, and no mushroom-specific claims are currently approved.
Legal Status in Australia
Australia is the notable exception. The Therapeutic Goods Administration (TGA) classifies lion’s mane as a novel food, and novel foods are prohibited from retail sale unless they appear on the list of permitted novel foods under Australia’s Food Standards Code. As of now, lion’s mane is not on that permitted list. This means you generally cannot buy lion’s mane supplements or food products over the counter in Australia the way you can in the U.S. or Europe. Importing it for personal use may also run into regulatory issues.
Importing and Traveling With Lion’s Mane
If you’re bringing lion’s mane into the United States, no special permit is required for mushrooms intended for consumption. The USDA’s Animal and Plant Health Inspection Service confirms that both fresh and dried mushrooms can enter the country as long as they are free of soil, insects, diseases, and contamination from other plant material. They will be inspected at the port of entry. Family members visiting from abroad can bring dried mushrooms into the U.S. under the same conditions.
Rules differ by country, though. If you’re traveling to Australia or another country with stricter novel food regulations, carrying lion’s mane supplements could be flagged at customs. Check your destination country’s food import rules before packing supplements in your luggage.
Safety Profile
A 2025 toxicology study published in Frontiers in Toxicology tested lion’s mane powder in rats at doses up to 2,000 mg per kilogram of body weight per day over a subchronic period. The researchers found no acute toxicity, no subchronic oral toxicity, and no genotoxicity (DNA damage) in either lab-based or live-animal tests. No animals died during the 14-day acute observation period, and the estimated lethal dose was greater than 2,000 mg/kg, which for context would translate to an enormous quantity in a human. Some minor organ weight changes were observed in females at the highest dose, but microscopic examination found no corresponding tissue abnormalities.
These results align with lion’s mane’s long history of use as food in East Asia and its generally well-tolerated profile in human supplement form. Still, the lack of FDA pre-market review means supplement quality can vary between brands, so choosing products from manufacturers that use third-party testing is a practical way to reduce risk.
