United States: food and supplement rules still apply
OPSS describes lion’s mane among commercially marketed mushroom supplements. Availability does not mean FDA approval of effectiveness. The actual ingredients, manufacturing and claims must meet applicable rules; a lion’s-mane label also does not authorize added controlled substances. [1][2]
European Union: a specific extract was found not novel
An official consultation concluded that the described lion’s-mane fruiting-body extract powder was not a novel food. It considered prior food use and a particular water/ultrasound process. That conclusion should not be broadened into automatic permission for every mycelium preparation, concentrated extract or health claim. [3]
United Kingdom: wild-species protection is a separate issue
The official protected-species list includes Hericium under the name Hericium erinaceum. A cultivated food product and collecting or selling wild material therefore need different legal checks. Consult the relevant wildlife authority rather than assuming retail availability permits wild harvesting. [4]
Check the transaction, not just the common name
Imagine an overseas seller offers a concentrated mycelium product. A decision about a fruiting-body water extract in another jurisdiction does not settle its import or sale status. Verify current rules for the destination, origin, preparation and proposed activity; this is not a worldwide legal clearance. [3][4]

| Country | Different applicable rules |
