Trusted resources, research and articles about Lion’s Mane
Lion’s Mane, also known as Hericium erinaceus, is one of the most talked-about functional mushrooms. It has been valued in traditional wellness practices and is now being studied for its naturally occurring compounds, including hericenones, erinacines, polysaccharides and beta-glucans.
At Dr Schimmel™, we believe customers should have access to clear, balanced and trustworthy information. This page brings together useful research, articles and expert insights so you can learn more about Lion’s Mane with confidence.
The research is promising, but still developing. Several human studies have explored Lion’s Mane in areas such as memory, cognition, mood, stress and wellbeing, although larger and longer studies are still needed. Memorial Sloan Kettering notes that limited clinical data suggest Lion’s Mane may improve memory and mood in some groups, while also making clear that more evidence is needed.
Why Lion’s Mane Is Being Studied
Lion’s Mane is attracting scientific interest because it contains naturally occurring compounds that researchers are exploring for their potential role in cognitive and wellbeing support.
Researchers have looked at Lion’s Mane in relation to:
Cognitive function
Studies have explored memory, attention, processing speed and cognitive performance.
Mood and stress
Some human trials have looked at subjective stress, anxiety, mood and emotional wellbeing.
Healthy ageing
Lion’s Mane has been studied in older adults and people with mild cognitive impairment.
Gut-brain connection
Some newer studies are exploring links between Lion’s Mane, gut microbiota and cognition.
Bioactive compounds
Researchers are interested in compounds such as hericenones, erinacines and mushroom polysaccharides.
Positive Research Highlights
1. Lion’s Mane and mild cognitive impairment
One of the best-known human studies looked at adults aged 50–80 with mild cognitive impairment. Participants taking Yamabushitake, another name for Lion’s Mane, showed improved cognitive function scores during the supplementation period. The study also reported that scores decreased after supplementation stopped.
This is one of the early human studies that helped drive interest in Lion’s Mane and cognitive wellbeing. Yamabushitake Trial. (Click for Report)
2. Lion’s Mane, stress and cognitive performance in young adults
A 2023 double-blind, placebo-controlled pilot study explored the acute and chronic effects of Lion’s Mane in healthy young adults. The researchers reported that findings tentatively suggested Lion’s Mane may improve speed of performance and reduce subjective stress, while also noting that more research is needed.
This study is interesting because it looked at healthy younger adults, not only older populations or clinical groups. Acute and Chronic Effects of Lion’s Mane on Cognitive Function. (Click for Report)
3. Lion’s Mane, mood and sleep
Human research has also explored Lion’s Mane in relation to mood and sleep. Memorial Sloan Kettering summarises limited clinical data suggesting possible benefits for memory and mood in certain groups, including overweight individuals, people with mild cognitive impairment, older adults and menopausal women.
This is why Lion’s Mane is often discussed as part of a daily wellbeing routine, although it should not be presented as a treatment for any medical condition. Memorial Sloan Kettering Cancer Center. (Click for Report)
4. Ongoing research into cognition
ClinicalTrials.gov lists current and recent studies looking at Lion’s Mane and cognitive function. One registered trial is investigating whether Hericium erinaceus extract can enhance selected cognitive functions in healthy, actively working, middle-aged women over an 8-week period.
Research is still active, which shows continuing scientific interest in Lion’s Mane. Effects of Lion's Mane for Middle Aged Women. (Click for Report)

Clinical Trials and Research Areas
Year 2024 - Cognition. (Click for Report)
Randomised, double-blind, placebo controlled pilot study on adults. Erinacine A-enrichedHericium erinaceus supplementation was studied for cognition in a pilot trial
Year 2023 - Cognition, Stress and Mood in young adults. (Click for Report)
Randomised, double-blind, placebo controlled pilot study on 41 healthy adults aged 18–45. Findings tentatively suggested faster Stroop task performance after an acute dose and a trend toward reduced subjective stress after 28 days, but authors stressed caution due to small sample size and mixed findings.
