Historical Use of Lion’s Mane in Traditional Medicine

Long before it gained attention in the world of modern supplements, Lion’s Mane was deeply rooted in traditional medicine for centuries. Its long history in Chinese and Japanese medicine helps explain why this unique mushroom, also known as the bearded tooth fungus, continues to inspire both curiosity and respect today.

Lion’s Mane in Traditional Chinese and Japanese Medicine

In traditional Chinese medicine, Lion’s Mane, known as Hóu Tóu Gū, was used in practices to support the spleen and digestive system, believed to be central to energy, vitality, and overall balance. It was also thought to nourish the “five internal organs,” contributing to a sense of internal harmony.

In Japanese herbal practice, Lion’s Mane, known as Yamabushitake, was also used in traditional medicine to enhance cognitive function. It’s said that Buddhist monks consumed it to enhance focus during meditation, reflecting its long-standing association with cognitive and spiritual well-being. Taking Lion’s Mane was believed to support mental clarity and promote mindfulness.

Scientific Research on the Benefits of Lion’s Mane

Modern interest in Lion’s Mane is driven by ongoing research exploring its potential effects on cognitive function, neurological health, and emotional well-being. While findings remain preliminary and more long-term studies are needed, early research offers intriguing insights.

Is Lion’s Mane Legal in the UK? Understanding the Regulations

Yes, Lion’s Mane is legal to buy, consume, and cultivate in the UK. It is commonly available in various forms, including powders, capsules, tinctures, and grow-at-home kits. However, there are important legal distinctions depending on how it is sourced or sold.

Legal Protection in the Wild

In the UK, wild Lion’s Mane is protected under Schedule 8 of the Wildlife and Countryside Act 1981—the highest level of legal protection for wild fungi in the UK. 

• It is illegal to pick, uproot, or damage wild Lion’s Mane mushrooms—whether for personal use or commercial gain.
• This legislation helps protect biodiversity and prevent further decline of this rare species in its natural habitat.

Growing Popularity and Market Trends

The interest in functional mushrooms like Lion’s Mane has surged in recent years. The global adaptogenic mushrooms market was valued at £8.7 billion in 2022 and is projected to grow at an annual rate of 10% over the next decade.

While Lion’s Mane is legal and increasingly popular, it is essential to source it responsibly. Opt for cultivated products from reputable suppliers to ensure quality and compliance with UK regulations. For those seeking high-quality, sustainably sourced mushroom blends, MOGU offers a range of products that combine functional mushrooms like Lion’s Mane with ceremonial-grade matcha, coffee, and cocoa.

Can You Buy Lion’s Mane in the UK?

Yes, Lion’s Mane is widely available in the UK, with various purchasing options to suit different preferences. You can find it in a range of product types, each serving different needs and usage methods:

• Fresh or Dried Mushrooms: Available at health food stores and online retailers, these can be used in cooking, teas, or infusions.
• Capsules or Powders: Found in supplement shops, pharmacies, and from direct-to-consumer brands, these are typically used for cognitive and immune support.
• Liquid Extracts: Sold by nootropic or wellness retailers, these offer high-bioavailability supplementation for quicker absorption.

Fresh and dried Lion’s Mane mushrooms are often used in cooking or teas, but they aren’t the most effective form for supplementation. That’s because many of the mushroom’s active compounds—such as beta-glucans, hericenones, and erinacines—are locked inside tough chitin cell walls, which the human digestive system can’t fully break down. Extracted Lion’s Mane supplements, on the other hand, go through multi-step extraction (using water and/or alcohol) to dissolve and release both water-soluble and alcohol-soluble compounds. The result is a concentrated product that delivers a significantly higher and more bioavailable dose of these key actives.

When buying Lion’s Mane, ensure that the product complies with UK food safety and labeling regulations. It's also important to choose brands that provide transparency, offer third-party testing, and share sourcing information for added quality assurance.

While Lion’s Mane isn’t classified as a controlled substance, Lion’s Mane products must still meet food supplement regulations to be legally sold in the UK.

Are There Any Restrictions on Selling or Growing Lion’s Mane?

Home Cultivation

You can legally grow Lion’s Mane at home using grow kits or on logs. There are no restrictions on personal cultivation, as long as the mushrooms are not foraged from protected wild sites. This makes it easy for enthusiasts to cultivate their own supply in a controlled environment.

Selling Supplements

Selling mushroom supplements and Lion’s Mane products such as capsules, powders, and extracts requires compliance with UK regulations, including:

• Food Supplements (England) Regulations 2003.
• General Food Labelling and Safety Laws.
• Advertising Standards regarding health claims.
  

Businesses must also register as food operators with their local authority and ensure that their products meet Good Manufacturing Practice (GMP) standards. This ensures that all products are safe, properly labeled, and responsibly marketed to consumers.

How to Choose a High-Quality Lion’s Mane Product

Not all Lion’s Mane supplements are the same. To ensure you're getting the best quality, look for the following indicators:

Additionally, avoid products that contain unnecessary fillers or those with proprietary blends that don’t disclose actual dosages. This ensures you’re getting the full benefit of each serving.

The Future of Lion’s Mane Regulation in the UK

As interest in functional mushrooms grows, regulations are likely to evolve to ensure safety, consistency, and efficacy. Here's what we may expect in the future:

• Stricter Quality Standards: Could lead to greater product consistency across the market, ensuring consumers receive high-quality products.
• Improved Labeling Requirements: More transparent and informative labels will help consumers make better-informed decisions about their purchases.
• Increased Clinical Research: Ongoing studies could provide the necessary data to support regulated health claims, offering consumers more confidence in the product’s benefits.
• Low Likelihood of Restriction: Since Lion’s Mane has no psychoactive effects and is widely accepted, it is unlikely to face significant regulatory restrictions.
  

For now, Lion’s Mane remains accessible, but as its popularity grows, we can expect rising scrutiny and more regulation to ensure safety and quality.

Final Thoughts: Is It Safe and Legal to Use Lion’s Mane in the UK?

Yes, Lion’s Mane is both legal and safe to use in the UK when purchased from reputable sources.

While foraging wild Lion’s Mane is prohibited under UK law, cultivated and commercially prepared Lion’s Mane mushrooms and supplements are widely available and subject to standard food and supplement regulations, rather than controlled substance laws.

If you're considering adding Lion’s Mane to your wellness routine, be sure to choose high-quality products. As with any supplement, it’s always a good idea to consult a healthcare provider, especially if you have any existing health conditions or concerns.
