What Is Lion's Mane Mushroom?

Lion's mane is a distinctive white mushroom whose fruiting body and mycelium both contain neuroactive compounds. Hericenones (from the fruiting body) and erinacines (from mycelium) are unique diterpene compounds that cross the blood-brain barrier and stimulate production of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF).

How It Works: The Science

Hericenones and erinacines stimulate NGF synthesis in neurons and astrocytes. NGF promotes neuronal survival, axon growth, and myelination. This mechanism supports regeneration of damaged peripheral nerves and may slow the neuronal loss associated with cognitive ageing. BDNF upregulation supports synaptic plasticity and neurogenesis.

Evidence-Based Benefits

Improves mild cognitive impairment in older adults

moderate

Mori et al. (2009) — 3g/day for 16 weeks significantly improved cognitive function vs placebo

Reduces anxiety and depression symptoms

moderate

Nagano et al. (2010) — 2g/day reduced anxiety and irritability in menopausal women

May support peripheral nerve regeneration

Dosage Guide

Effective Dose

500–3000mg / day

500–3000mg/day. Fruiting body extracts (with ≥30% beta-glucans) are preferred over mycelium on grain (high starch content, low active compounds). Use hot water or dual extracts to access both beta-glucans and hericenones.

Safety Profile & Side Effects
