What is Lion's Mane?
Lion's Mane supplements (Hericium erinaceus) is an edible mushroom that has been used for centuries in traditional Chinese and Japanese medicine. It gets its name from its unusual appearance — white, cascading spines resembling a lion's mane.
Lion's mane has risen to become one of the most popular functional mushrooms in recent years, particularly due to its nootropic properties. Unlike most supplements, lion's mane may actually stimulate the growth of new nerve cells.
Lion's mane unique bioactive compounds:
- Hericenones — stimulate NGF (nerve growth factor)
- Erinacines — support BDNF (brain-derived neurotrophic factor)
- Beta-glucans — support the immune system
- Polysaccharides — antioxidant and anti-inflammatory
Benefits of Lion's Mane
Nerve Growth Factor (NGF) Stimulation
NGF is a protein essential for nerve growth, maintenance, and survival. Lion's mane is one of the few natural substances that stimulates NGF production.
Mori et al. (2008) laboratory study:
- Lion's mane hericenones stimulated NGF synthesis in vitro
- NGF is necessary for neuron growth and myelin sheath formation
Cognitive Function
This is perhaps the most important study on lion's mane.
Mori et al. (2009) clinical trial:
- 30 Japanese older adults with mild cognitive impairment
- 3g lion's mane mushroom powder daily for 16 weeks
- Significant improvement in cognitive function compared to placebo
- Unfortunately, improvement disappeared 4 weeks after discontinuation
This suggests that lion's mane needs to be consumed continuously for benefits to persist.
Mood and Anxiety
Lion's mane may also support mental well-being.
Nagano et al. (2010) study:
- 30 women for 4 weeks
- Lion's mane cookies vs placebo cookies
- Reduced anxiety and irritability in the lion's mane group
- Better concentration
Digestive Health
Lion's mane has been traditionally used for digestive issues:
- Supports stomach lining health
- May help with inflammatory bowel disease
- Prebiotic properties — supports gut microbiome
Study (Qin et al., 2016):
- Lion's mane polysaccharides supported the stomach lining and reduced damage in animal models
Immune System Support
Lion's mane beta-glucans support the immune system:
- Activate macrophages and NK cells
- Modulate immune response (do not overstimulate)
- Support gut immune system
Fruiting Body vs Mycelium: An Important Distinction
Lion's mane products are made in two ways, and the difference matters:
Fruiting Body Extract
- Higher concentration of bioactive compounds
- Contains hericenones and erinacines
- Best choice for evidence-based use
- More expensive but more effective
Mycelium-Based Product
- Grown on grain (typically rice)
- Lower concentration of bioactive compounds
- Contains significant starch from the grain
- Cheaper but less effective
Recommendation: Choose fruiting body extract for maximum benefit.
