Yes, Lion’s Mane mushroom has been shown to stimulate Nerve Growth Factor (NGF) production, which may support brain regeneration by encouraging the growth, repair, and protection of neurons.

Lion’s Mane and Its Unique Effect on the Brain
Lion’s Mane (Hericium erinaceus) is a medicinal mushroom long used in traditional Chinese and Japanese medicine. In recent years, it has gained attention in neuroscience and nootropic communities for its potential to enhance neurogenesis and neuroplasticity — two essential processes for brain regeneration and cognitive resilience.
Unlike many other natural nootropics, Lion’s Mane doesn’t work by stimulating neurotransmitter levels or providing a short-term cognitive lift. Instead, it operates at the structural level, encouraging the growth and repair of nerve cells through increased NGF activity.
1. What Is Nerve Growth Factor (NGF)?
Nerve Growth Factor is a protein that plays a vital role in the development, maintenance, and survival of neurons. It supports the growth of axons and dendrites, the structures responsible for transmitting and receiving electrical impulses across brain networks. Higher NGF activity can help protect the brain from age-related decline and support recovery from injury or oxidative stress.
However, NGF is a large molecule that cannot cross the blood-brain barrier when taken directly. This makes internal stimulation of NGF production — such as through Lion’s Mane compounds — especially valuable.
2. Hericenones and Erinacines: The Active Compounds
Lion’s Mane contains two unique types of compounds: hericenones (found in the fruiting body) and erinacines (found in the mycelium). Both have been shown in animal and in vitro studies to stimulate NGF synthesis in brain tissue. Erinacine A, in particular, has demonstrated strong neurotrophic activity in the central nervous system.
In a landmark 1994 study published in Planta Medica, researchers discovered that ethanol extracts of Lion’s Mane promoted NGF secretion in nerve cells. This was a key moment that launched a wave of scientific interest in the mushroom’s regenerative properties.
3. Promoting Neurogenesis and Synaptic Repair
Increased NGF production leads to downstream benefits like neurogenesis (the formation of new neurons) and synaptogenesis (the repair or creation of new synaptic connections). This has promising implications for learning, memory, and long-term cognitive resilience.
A 2013 animal study in the Journal of Restorative Neurology and Neuroscience found that Lion’s Mane supplementation enhanced hippocampal neurogenesis in aged mice, which correlated with improvements in memory and recognition tasks. This points to its potential not only for brain repair, but also for enhancing cognitive performance in healthy individuals.
4. Human Studies on Cognitive Function
While much of the strongest evidence comes from animal models, human research is growing. In a 2009 double-blind, placebo-controlled study published in Phytotherapy Research, elderly Japanese adults with mild cognitive impairment took 250 mg of Lion’s Mane powder three times daily for 16 weeks. They showed significant improvement in cognitive function compared to placebo — and their scores declined after discontinuation, suggesting a direct, active effect from the mushroom.
Though more human research is needed, these early results support the idea that Lion’s Mane may help preserve or even improve brain function in aging populations by facilitating neural repair and regeneration.
Who Might Benefit from Lion’s Mane?
Because Lion’s Mane supports NGF and may promote structural repair of brain tissue, it has a wide range of potential applications:
- Individuals recovering from brain injury or stroke
- Older adults concerned about age-related cognitive decline
- Biohackers and nootropic users looking to support long-term neuroplasticity
- Students or professionals under chronic stress who may experience impaired neural connectivity
Additionally, its antioxidant and anti-inflammatory properties further support brain health, making it a comprehensive nootropic for both prevention and restoration.
A Natural Ally for Brain Regeneration
Lion’s Mane stands out among nootropic ingredients for its rare ability to stimulate Nerve Growth Factor and support actual brain regeneration. Through its hericenone and erinacine compounds, it promotes the growth, repair, and maintenance of neurons, making it valuable for cognitive protection and long-term brain health.
It’s no surprise that Lion’s Mane is a core ingredient in advanced nootropic stacks like Mind Lab Pro, where it contributes to neuroplasticity, memory enhancement, and lifelong brain support.
