Hericium Erinaceus Mushroom Mycelium Powder
Also known as: Lion’s Mane mushroom, Yamabushitake, Hericium erinaceus mycelium powder, Hericium erinaceus
Overview
Hericium erinaceus mycelium powder is derived from the vegetative part of the Lion's Mane mushroom, containing bioactive compounds such as erinacines and hericenones. These compounds are believed to promote nerve growth factor (NGF) synthesis and neuroprotection, making it a popular supplement for cognitive enhancement and neurological health. It is primarily used to improve cognitive function, provide neuroprotection, enhance mood, reduce anxiety, and improve sleep quality. Research on H. erinaceus mycelium is moderately mature, with a growing number of in vitro, in vivo, and clinical studies, including randomized controlled trials. While systematic reviews specifically on mycelium powder are emerging, more large-scale RCTs are needed to solidify the evidence base. The supplement is typically consumed in powder or capsule form.
Benefits
Hericium erinaceus mycelium powder offers several evidence-based benefits. It exhibits neuroprotective and cognitive benefits, primarily due to erinacine A, which stimulates NGF synthesis, promoting neuronal growth and repair in both in vitro and in vivo studies. Clinical studies indicate that supplementation can reduce anxiety and depressive symptoms, possibly through hippocampal neurogenesis and modulation of BDNF pathways. Animal studies also suggest improvements in sleep disruptions and associated anxiety, with effects on sleep architecture. A double-blind randomized controlled trial in healthy young adults showed that 1.8 g/day improved cognitive speed and reduced subjective stress after 4 weeks. Furthermore, evidence supports benefits in overweight/obese patients with mood and sleep disorders, showing improvements in depression, anxiety, and sleep quality after 8 weeks of supplementation. While effect sizes vary, several studies report statistically significant improvements with moderate clinical relevance.
How it works
The primary mechanism of action for Hericium erinaceus mycelium powder involves its unique bioactive compounds, erinacines (especially erinacine A) and hericenones. These compounds are crucial for stimulating the synthesis of Nerve Growth Factor (NGF) and Brain-Derived Neurotrophic Factor (BDNF), both essential proteins for neuronal survival, differentiation, and synaptic plasticity. Erinacines are notable for their ability to cross the blood-brain barrier, allowing them to directly influence central nervous system pathways. They interact with signaling pathways such as TrkB/PI3K/Akt/GSK-3β, which are involved in neurogenesis and mood regulation. Additionally, the bioactive compounds in the mycelium modulate neurotransmitter systems and reduce neuroinflammation, contributing to its anxiolytic and antidepressant effects. While absorption and bioavailability have been demonstrated in animal models, human pharmacokinetics require further investigation.
Side effects
Hericium erinaceus mycelium powder generally exhibits a good safety profile and is well tolerated in clinical trials. Common side effects are rare and, when they occur, are typically mild, primarily involving gastrointestinal discomfort. No significant drug interactions or contraindications have been widely reported in the reviewed literature. However, it is important to note that data on specific populations, such as pregnant women, breastfeeding mothers, and children, are insufficient. Therefore, individuals in these groups should exercise caution and consult a healthcare professional before use. As with any supplement, individuals with pre-existing medical conditions or those taking other medications should seek medical advice to ensure safety and avoid potential interactions, although none are currently well-documented.
Dosage
Effective doses of Hericium erinaceus mycelium powder in clinical trials typically range from 1.8 grams per day (often administered as three 600 mg capsules) to approximately 3 grams per day of the mycelium extract. For cognitive and mood benefits, a duration of supplementation between 4 to 8 weeks is commonly observed in studies to achieve noticeable effects. The supplement is usually taken orally, and administration after meals is often recommended to optimize absorption. For consistency and efficacy, it is advisable to use standardized extracts that have quantified erinacine A content. While specific upper limits are not well-defined, adherence to recommended dosages from clinical studies is prudent. Always follow product-specific instructions or consult a healthcare professional for personalized dosing advice.
FAQs
Is it safe for long-term use?
Current evidence supports the safety of Hericium erinaceus mycelium powder for short-to-medium term use. However, long-term safety data are still limited, and more research is needed.
How soon do benefits appear?
Cognitive and mood improvements from Hericium erinaceus mycelium powder have typically been observed within 4 to 8 weeks of consistent supplementation in clinical studies.
Can it replace prescription medications?
No, Hericium erinaceus mycelium powder is a complementary supplement and should not be used as a substitute for prescribed medications or treatments for any medical condition.
Does it work for everyone?
Response to Hericium erinaceus mycelium powder may vary among individuals. Benefits are more consistently documented in populations experiencing mild cognitive or mood impairments.

- https://www.frontiersin.org/journals/pharmacology/articles/10.3389/fphar.2025.1582081/full – This systematic review of preclinical studies highlights that erinacine A, a key compound from Hericium erinaceus mycelium, effectively stimulates Nerve Growth Factor (NGF) synthesis and provides neuroprotection in both in vitro and in vivo models. The findings provide strong mechanistic insights into the mushroom's potential neurotrophic effects, although direct clinical translation requires further human studies.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC10675414/ – This double-blind randomized controlled trial involving 30 healthy young adults demonstrated that supplementing with 1.8 g/day of Hericium erinaceus mushroom complex for 4 weeks significantly improved cognitive speed and reduced subjective stress. The study provides evidence for the cognitive benefits of the supplement in a healthy population, despite its relatively small sample size.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC8643634/ – An in vivo animal study using a mouse model showed that Hericium erinaceus mycelium improved sleep disruption and anxiety, likely through its influence on BDNF pathways. This research provides valuable mechanistic evidence for the mushroom's anxiolytic and sleep-modulating effects, though its applicability to humans needs further investigation.
- https://onlinelibrary.wiley.com/doi/10.1155/2019/7861297 – This clinical trial, involving 77 overweight/obese adults with mood and sleep disorders, found that 8 weeks of Hericium erinaceus supplementation significantly reduced symptoms of depression and anxiety, and improved sleep quality. While the study's open-label design is a limitation, it suggests promising benefits for these specific populations.
