Overview
Lion’s Mane is a medicinal mushroom that has been used in traditional Chinese and Japanese medicine for centuries. In recent years, it has gained significant scientific attention for its potential effects on brain health, cognition, and nerve regeneration.
Unlike many plant compounds, Lion’s Mane contains unique bioactive molecules (hericenones and erinacines) that are able to stimulate Nerve Growth Factor (NGF), a protein essential for the growth, maintenance, and survival of neurons.
This makes Lion’s Mane one of the most promising natural compounds for supporting cognitive function and healthy brain ageing.
Nutrient Profile
Lion’s Mane contains a range of biologically active compounds:
- Hericenones and erinacines — associated with NGF stimulation - Polysaccharides — supporting immune and metabolic health - Antioxidants — reducing oxidative stress - Beta-glucans — contributing to immune modulation
These compounds underpin Lion’s Mane’s neurological and systemic effects.
Why We Include It
Lion’s Mane is included for its potential role in supporting cognitive function, memory, and long-term brain health.
NGF plays a central role in neuroplasticity and neuronal repair. By stimulating NGF production, Lion’s Mane may support the maintenance and regeneration of neurons, which is particularly relevant for ageing populations.
From a longevity perspective, preserving cognitive function is one of the most important determinants of quality of life, making Lion’s Mane a key ingredient within a brain-supportive nutritional strategy.
Evidence & References
Study 1 — Cognitive Function in Mild Cognitive Impairment
Type: Randomised, double-blind, placebo-controlled trial Population: Older adults with mild cognitive impairment Duration: 16 weeks
Key Finding: Participants receiving Lion’s Mane showed significant improvements in cognitive function compared with placebo. Why it matters: Provides direct human evidence supporting Lion’s Mane for cognitive health.
Source: https://pubmed.ncbi.nlm.nih.gov/18844328/ Study 2 — Cognitive Decline After Discontinuation
Type: Follow-up study of RCT participants
Key Finding: Cognitive function declined after stopping Lion’s Mane supplementation. Why it matters: Suggests that continued intake may be required to maintain benefits.
Source: https://pubmed.ncbi.nlm.nih.gov/18844328/ Study 3 — Mood and Anxiety
Type: Randomised, placebo-controlled trial Population: Adults with depressive and anxiety symptoms
Key Finding: Lion’s Mane supplementation was associated with improvements in mood and reductions in anxiety symptoms. Why it matters: Suggests broader neurological benefits beyond cognition.

Supporting Evidence — Mechanistic & Review Data
Type: Review
Key Finding: Lion’s Mane compounds (erinacines and hericenones) stimulate NGF synthesis and may support neurogenesis, neuroprotection, and cognitive function. Why it matters: Provides a strong biological mechanism underpinning observed human effects.
