Lion's Mane. Edible medicinal mushroom that upregulates NGF and BDNF — studied for nerve growth and cognition.
How it works. Hericenones and erinacines stimulate synthesis of nerve growth factor (NGF) in neurons. BDNF also appears upregulated.
What the research supports. 3 graded claims. Strongest: Improves cognitive function in mild cognitive impairment (limited).
How much to take. Typical dose: 1,000–3,000 mg fruiting-body extract/day. Morning, with food.
Side effects and interactions. 2 medication interactions listed. No serious side effects listed at normal doses.
Stacking. Pairs well with Omega-3 (DHA), Bacopa monnieri.
Common forms. Available as Fruiting body extract (hericenones — best for cognition), Mycelium on grain (lower potency, may contain starch filler).
Key studies. 10 studies cited. The strongest are listed with links to PubMed.
Community. Experiences from people who have tried Lion's Mane. Anecdotes are not medical advice.

What it is
An edible mushroom with hericenones (fruiting body) and erinacines (mycelium) that cross the blood-brain barrier and stimulate nerve growth factor (NGF).

Goals
How it works
Hericenones and erinacines stimulate synthesis of nerve growth factor (NGF) in neurons. BDNF also appears upregulated.
Pathways
- NGF upregulation
- BDNF upregulation
- Anti-inflammatory (microglial)
Effects
- ↑NGF expression increases
- +Cognitive function in mild impairment supports
- ↓Mild anxiety/depression symptoms decreases
- +Peripheral nerve regeneration (animal data) supports
What the research supports
Strong: consistent results across large trials or meta-analyses. Moderate: several trials, mostly positive. Limited: small or mixed studies. Preclinical: animal or cell research only.
