Lion's Mane
The only natural substance proven to stimulate nerve growth factor (NGF). What if you could regrow your brain's wiring?
Quick Facts
Latin Name
Hericium erinaceus
Active Compounds
Hericenones, erinacines (NGF stimulators)
Primary Use
Cognitive enhancement, nerve regeneration, gut health
Form
Fruiting body extract, powder, fresh
What It Is
Lion's mane is an edible mushroom that looks like cascading white icicles or, yes, a lion's mane. It grows on hardwood trees and has been used in Asian medicine for centuries for digestive and cognitive support.
What makes it unique is the discovery that it stimulates NGF (nerve growth factor) production — the protein that grows and maintains neurons. This is unprecedented in the natural world.
How It Works
- →NGF stimulation: Hericenones and erinacines cross the blood-brain barrier and increase NGF production
- →Neurogenesis: Promotes growth of new neurons and repair of damaged ones
- →Myelin support: May help rebuild myelin sheaths that insulate nerve fibers
- →Gut-brain axis: Benefits gut lining, which influences brain through vagus nerve
Research Highlights
This isn't just traditional medicine — there's real research:
• Improved cognitive function in mild cognitive impairment (human trial)
• Reduced anxiety and depression symptoms (human trial)
• Nerve regeneration after injury (animal studies)
• Protection against Alzheimer's markers (in vitro and animal)
When to Use It
Cognitive enhancement
Focus, memory, mental clarity — works over weeks/months
Nerve damage/neuropathy
Supporting nerve regeneration after injury or in degenerative conditions
Anxiety and depression
Research shows mood benefits — possibly through gut-brain axis
Gut health
Traditional use for digestive issues, gastritis, ulcers
Why Form Matters
Lion's mane has two sets of active compounds in different parts:
• Hericenones: Found in the fruiting body (the visible mushroom)
• Erinacines: Found in the mycelium (underground network)
• Best choice: Fruiting body extract OR products combining both
• Avoid: "Mycelium on grain" — mostly grain, little mushroom
Dosing Protocol
Extract (fruiting body)
500-1000mg, 2-3x daily
Fresh mushroom
3-5g daily — can be cooked like any mushroom
Tincture (dual-extract)
1-2 droppers, 2x daily
Effects build over 2-4 weeks. Safe for long-term daily use. Some people cycle it; others take continuously.
Contraindications
- • Mushroom allergy: If allergic to other mushrooms, start very small
- • Blood thinners: May have mild antiplatelet effects
- • Surgery: Consider stopping 2 weeks before
- • Pregnancy/breastfeeding: Not enough safety data
