What is lion's mane?

Lion’s mane, also known as hericium erinaceus, is a large white mushroom that grows on the trunks of dead hardwood trees, including oak, beech, elm, birch and maple. Fuzzy and hairy in appearance, it gets its name thanks to its resemblance to a lion’s mane as it grows. 

The mushroom has been used for centuries in traditional East Asian medicine and cooking and contains bioactive substances that might help improve nerve development and function as well as a host of other benefits on the brain, heart and stomach.

It can also be used to provide relief from stress, anxiety and depression and can protect nerves from being damaged. Research suggests it improves cognition and has promising results in even potentially preventing or treating Alzheimer’s and dementia

Can you get lion's mane in the UK?

Luckily for us, these non-psychedelic, pom-pom-like mushrooms are completely legal to buy and use in the UK. They can be purchased as fresh, dried, powders from food shops and markets or as supplements at Novomins. It's even legal to grow them, although we wouldn't necessarily recommend it.

Think you've spotted one in the wild when you were out and about? While it's perfectly fine to take a snap or two on your phone or camera and admire its unique and shaggy appearance, make sure to leave it well alone! 

Lion's mane is a very rare fungus in the UK and, as such, is protected under Schedule 8 of the Wildlife and Countryside Act 1981. This is the highest legal protection for fungi and other plants, making them illegal to collect.

What does taking lion's mane do for you?

Lion’s mane is increasingly gaining popularity in the UK and other Western countries thanks to its many potential health-boosting benefits. Containing natural bioactive compounds, these unassuming mushrooms provide potential disease-fighting properties.

Other UK lion’s mane mushroom benefits include:

Brain and memory support

Research suggests that lion's mane can help boost cognitive function. That’s because the mushroom is a nootropic, meaning it contains compounds like hericenones and erinacines, which improve brain health and protect it from cognitive decline due to ageing. 

As a result, lion’s mane may help support cognitive function, including boosting memory. Studies have shown that its effect on nerve growth factor levels may even help protect the brain against dementia and Alzheimer's disease.     

Stress and anxiety reduction

Thanks to its effect on nerve growth, studies suggest that lion's mane has a mood-enhancing effect and can improve mental health, alleviating symptoms of stress, anxiety and depression. 

The 2010 Biomedical Research study looked at the effects of lion's mane on brain function and concluded that participants who consumed the mushroom for four weeks reported less anxiety compared to the placebo group. 

Another study in menopausal women observed lowered anxiety and depression after just four weeks of supplementation.   

Immune system support

Needing a boost? Lion's mane may be exactly what you need. 

Research in animals highlights that it may strengthen and boost the immune system, helping your body better protect itself against nasty bacteria and viruses, like the cold and flu. 

It does this by increasing the activity in the intestinal system, helping regulate the bacteria in the gastrointestinal tract, which protects the body from harmful substances that make their way down through the mouth or nose. 

Overall well-being

Lion’s mane contains health-promoting chemicals and displays disease-fighting properties, including antioxidant and antimicrobial activity. This helps improve overall health and well-being, including aiding better sleep. 

It also improves gut health, supporting the digestive tract and protecting the intestines and stomach lining from inflammation and diseases like ulcerative colitis. In fact, it’s been shown to help prevent ulcers by stopping the growth of helicobacter pylori bacteria, which can damage the gut lining. 

Lion’s mane for ADHD

There aren't any studies or clinical trials supporting lion's mane as an ADHD treatment. However, some people use it to help ADHD because it enhances brain function. It can also alleviate symptoms of mental health disorders like anxiety and depression, which often accompany ADHD.

What is the downside of lion's mane?

Unfortunately, there haven’t been any studies on the side effects of lion's mane in humans. However, the mushroom is generally well tolerated and considered safe for people to use with no serious adverse effects in animal studies, even at high doses.  

Any side effects tend to be mild, the most common including nausea, gastrointestinal discomfort or a rash on the skin. Anyone allergic or sensitive to mushrooms should avoid lion's mane entirely. 

Due to the lack of information, lion's mane isn't recommended for those who are pregnant or breastfeeding. If you are taking lion’s mane mushroom supplements, you should always stick to the recommended dose. If you do experience any negative side effects when consuming lion's mane, discontinue use immediately and speak with your health care provider.

Lion's mane powders

Made from dried mushrooms, lion's mane powder tends to be less expensive compared to supplements. It’s also less potent. 

These UK lion’s mane supplements are versatile and can be added to various foods and drinks. You can mix them into smoothies, water or hot beverages like coffee or tea. They also work well in baked goods such as cakes or pasta dishes, making it convenient to incorporate them into your diet.

Lion’s mane extracts are more powerful than powders and can be found in tinctures. You can generally add lion's mane extract to any food or drink or take it on its own. Be aware that it can cause some stomach discomfort due to its potency, especially if you're new to taking lion's mane.

Lion's mane tincture

Lion's mane tinctures are easier for dosage control than powders and are much more concentrated when compared to powdered extracts. 

Tinctures are generally either water or alcohol-based (ethanol). They can be taken under the tongue, causing lion's mane to enter the bloodstream much faster than powders, regular capsules or gummy supplements. 

While tinctures are one of the most effective ways to consume lion's mane, they can have a very strong taste that some might find unpleasant. 

Lion's mane tea

Lion's mane can also come in an easy-to-prepare powdered or loose tea format. All you have to do is add some to a cup, pour in hot water and stir. 

They tend to be savoury in flavour, so you can add powdered teas to smoothies and coffees like a regular lion's mane powder to help mask the taste.
