    What is lion’s mane mushroom? 

    In recent years, there has been a surge of interest in natural remedies to support overall well-being, and one such powerhouse gaining attention is the Lion’s Mane mushroom. This unique fungus, scientifically known as Hericium erinaceus, has a long history of use in traditional medicine, particularly in Asian cultures like China and Japan. However, its popularity is now spreading worldwide, thanks to emerging research highlighting its remarkable health benefits.

    What is lion’s mane mushroom good for? 

    Brain fog, concentration and brain health

    One of the most celebrated benefits of Lion’s Mane mushroom is its potential to support cognitive function and overall brain health. 

    Brain fog can be caused by various illnesses, most famously covid and long covid. It also sometimes results from overworking, lack of sleep, depression or stress, and it’s a typical menopause symptom. On a cellular level, brain fog is usually a consequence of high levels inflammation, and changes to hormones that determine your mood, energy and focus. The hormonal factor is why it’s so common during peri-menopause and after giving birth. 

    Studies suggest that compounds in Lion’s Mane, such as hericenones and erinacines, are good for the growth of brain cells. Scientists think they stimulate the production of nerve growth factor (NGF). This protein is essential for us to grow neurons and keep our nerves healthy – including the ones that make up our brains. By enhancing NGF activity, Lion’s Mane mushroom may help improve memory, focus, and mental clarity. 

    Stress relief and better mood

    Beyond cognitive enhancement, Lion’s Mane mushroom has also been studied for its potential mood-regulating properties. Research indicates that Lion’s Mane extracts may be good for anxiety and depression by modulating neurotransmitters that keep up a positive mood. Additionally, its adaptogenic properties can help the body better cope with stress and promote calm and well-being.

    Support for the nervous system and nerve healing

    Some studies suggest that Lion’s Mane extracts may help protect against neurodegenerative conditions like Alzheimer’s and Parkinson’s disease. They do this by reducing oxidative stress and inflammation in the brain. Indeed, it may be good for keeping our brains young and helping to prevent senile dementia or general cognitive decline.

    A study on rats found that extract of lion’s mane mushroom could make their nerves heal faster. 

    Gut Health and digestion

    Interestingly, Lion’s Mane mushroom also seems to be good for gut health and digestion. As a prebiotic, it nourishes beneficial probiotic gut bacteria. This helps maintain a healthy microbial balance in the digestive tract, improving digestion. This actually helps us absorb more nutrients from our food, and strengthens the immune system too.

    Potential immune system boosting

    Some research has found that lion’s mane mushroom extract kills various types of bacteria, with results strong enough to suggest it could be researched for medicinal use. Emerging research also suggests that Lion’s Mane mushroom may be good for our immune system in more than one way. Indeed, it can influence immune cell activity and improve our natural immune defences. By supporting immune function, Lion’s Mane mushroom may help protect against infections and promote overall vitality and resilience.

    Antioxidant to relieve illness symptoms

    Oxidative stress plays a major role in damaging body tissues when we are ill, whether it’s a short illness or a chronic condition. Researchers have found that the carotenoids and certain other substances in lion’s mane mushroom extract can neutralise free radicals (the harmful molecules containing oxygen) and stop this damage. 

    What’s the easiest way to get lion’s mane mushroom in the UK?

    Taking Lion’s Mane mushroom to your daily routine is easy and convenient, thanks to the availability of lion’s mane powder capsules. When choosing a Lion’s Mane supplement, go for organic mushroom extracts. Choose a brand that has independent third-party laboratory testing to make sure it’s free from contamination – remember mushrooms grow on all kind of rotting matter and they absorb just about anything you feed them.

    Start with the recommended dosage or less, and gradually adjust it upwards if you want, based on your individual response.
