Lion's Mane
Also known as: Hericium erinaceus, Yamabushitake
The only mushroom shown to stimulate nerve growth factor production — a promising nootropic for cognitive health and neuroprotection.
What it is
Lion's Mane (Hericium erinaceus) is a medicinal mushroom consumed in East Asian cuisine and traditional medicine for centuries. It has attracted significant scientific interest due to its unique ability to stimulate the synthesis of nerve growth factor (NGF) — a protein essential for the survival, maintenance, and regeneration of neurons. Research is ongoing, but early human trials show promising results for cognitive function and mild cognitive impairment.
How it works
Two classes of bioactive compounds — hericenones (found in the fruiting body) and erinacines (found in the mycelium) — cross the blood-brain barrier and stimulate NGF and BDNF production. NGF supports the survival of peripheral sensory neurons and cholinergic neurons in the brain — cells heavily impacted in Alzheimer's disease. Human trials show improvements in cognitive test scores, depression scores, and anxiety over 8–16 weeks of supplementation.
Clinical dose range
500–3,000 mg standardized extract/day
Clinical trials use 500 mg (standardized) to 3,000 mg of fruiting body extract or mycelium extract. Higher doses used for cognitive impairment studies. Fruiting body and mycelium extracts have different bioactive profiles — fruiting body is preferred for hericenones.
Forms comparison
What to look for on the label
- Fruiting body specified on label (not just 'mushroom' or 'mycelium on grain')
- Beta-glucan content disclosed (≥20% is a quality indicator)
- Third-party tested for heavy metals and pesticides
- Hot-water extracted (not raw powder) for beta-glucan and hericenone release

Safety & dosing notes
Excellent safety profile in clinical studies. Rare reports of skin rash (possible mushroom allergy). May interact with anticoagulants — monitor if taking blood thinners. No established UL.
SuppsBuddy checks for fruiting body specification, beta-glucan disclosure, and extraction method. Mycelium-on-grain products without active compound verification receive the lowest form score. Hot-water extraction is flagged as the quality standard.

Fruiting body and mycelium extracts have different bioactive profiles — fruiting body is preferred for hericenones.
What forms of Lion's Mane should I look for?
Fruiting body extract (hot water extracted): Contains hericenones and verified beta-glucan content; matches research methodology | Dual extract (fruiting body + mycelium): Provides both hericenones and erinacines for the most complete bioactive profile | Mycelium extract: Contains erinacines; typically grown on grain substrate which dilutes active compound content | Mycelium on grain (unextracted): Predominantly grain starch — minimal actual mushroom content or activity
Is Lion's Mane safe?
Excellent safety profile in clinical studies. Rare reports of skin rash (possible mushroom allergy). May interact with anticoagulants — monitor if taking blood thinners. No established UL. This information is educational and is not medical advice.
How does SuppsBuddy evaluate Lion's Mane?
SuppsBuddy checks for fruiting body specification, beta-glucan disclosure, and extraction method. Mycelium-on-grain products without active compound verification receive the lowest form score. Hot-water extraction is flagged as the quality standard.
