Lion's Mane Supplement

Lion’s Mane (Hericium erinaceus) is valued for its potential to support memory, focus, mental clarity and mood. Its natural compounds, hericenones and erinacines, are believed to stimulate nerve growth factor (NGF), which helps protect and repair brain cells. Studies suggest daily use can aid cognitive performance and emotional wellbeing, especially during periods of stress or fatigue.

Taking Lion’s Mane daily allows its active compounds to build up gradually, supporting brain and nerve health, cognitive functioning and mood over time. Most studies show results after 4–8 weeks of consistent use, with benefits maintained only while supplementation continues.

Lion’s Mane works through a combination of neurotrophic, anti-inflammatory and antioxidant mechanisms that appear to support brain and nerve health. Its key bioactive compounds — known as hericenones (from the fruiting body) and erinacines (from the mycelium) — are thought to stimulate the production of nerve growth factor (NGF), a protein that helps brain cells grow, survive and form new connections. NGF plays an important role in maintaining healthy communication between neurons, particularly in areas linked to memory and learning. Lion’s Mane also contains beta-glucans and polysaccharides, which can help modulate inflammation and support immune balance. Chronic low-grade inflammation and oxidative stress are both known to contribute to cognitive decline, so these antioxidant and anti-inflammatory effects may help protect delicate neural tissue from damage over time.

Yes, and the combination is popular for cognitive support. Ginkgo biloba helps boost blood flow to the brain, while Lion’s Mane supports nerve regeneration and repair. Together, they may enhance memory and focus.

Most people notice subtle effects like better focus or mood after a few weeks. Clinical trials suggest significant changes appear around 4–12 weeks of consistent use (Nagano, M. et al. (2010) ‘Reduction of depression and anxiety by 4-week H. erinaceus intake’, Biomedical Research, 31(4), pp. 231–237. (Randomised trial) found improvements in mood after 4 weeks and Surendran, G. et al. (2025) ‘Acute effects of a standardised H. erinaceus extract on cognition and mood in healthy adults’, Frontiers in Nutrition. (Double-blind RCT)reported improved cognitive functioning after 3 months of using lion’s mane.

You can take it either time, but many prefer morning or daytime use for improved clarity and energy. If you find it too stimulating later in the day, switch to morning.

Side effects of lion’s mane are rare, but can occasionally include mild digestive upset or itching. A few case reports describe allergic reactions, so avoid it if you have a mushroom allergy. Always choose a lab tested supplement to minimise the risk of contaminants.

Avoid Lion’s Mane if you have a mushroom allergy, are pregnant or breastfeeding, or are taking immunosuppressant medication. It’s not known to harm the liver, in fact some animal studies suggest it may even be protective of the liver. However, if you have any pre-existing medical condition, always consult your doctor before starting lion’s mane or any other herbal supplement.

Whilst there isn’t enough clinical research to say there’s conclusive proof, the research projects done so far had positive results in terms of improved cognitive functioning and less anxiety and depression. In a 16-week double-blind trial, older adults taking Lion’s Mane scored higher on cognitive tests than those taking a placebo (Mori, K. et al. (2009) ‘Improving effects of Hericium erinaceus on mild cognitive impairment’, Phytotherapy Research, 23, pp. 367–372. (Double-blind RCT)) A 4-week study also found lower anxiety and depression scores in the test subjects who were given lion’s mane (Nagano, M. et al. (2010) ‘Reduction of depression and anxiety by 4-week H. erinaceus intake’, Biomedical Research, 31(4), pp. 231–237. (Randomised trial)). Larger studies are ongoing 

There are discussions in forums online about people with ADHD trying lion’s mane, and some people say they feel better concentration and calmness - but these effects are just anecdotal and not clinically proven. So far, there has not been any clinical research specifically into how lion’s mane might help people with ADHD.

Ashwagandha and lion’s mane have different effects, and are taken for different health goals. Lion’s Mane supports cognitive and nerve health, while Ashwagandha is best known for stress relief and relaxation. It’s safe to take both - Ashwagandha in the evening, Lion’s Mane in the morning — to support both needs.
