What Is Lion’s Mane and Why the UK Trend?

Lion’s Mane (Hericium erinaceus) is a distinctive white mushroom, traditionally used in Asian medicine, that resembles a lion’s mane. Today, it’s widely sold in the UK as capsules, extracts, powders, gummies, and even M&S mushroom “shots” and lattes designed to enhance focus.

Under UK law, wild Lion’s Mane is protected—you can’t forage it, as it’s listed under the Wildlife and Countryside Act 1981. Instead, opt for farm-grown mushrooms or supplements with transparent sourcing.

Clinical studies indicate Lion’s Mane can support serotonin and dopamine pathways, potentially reducing anxiety and depression symptoms, especially in menopausal women after 4–8 weeks of supplementation.
