Lion's Mane Mushroom Benefits: Brain Health, Memory, Focus & More

How we found our first lion's mane mushroom — and why it changed everything

It was 2014, long before Manuka Mana existed, when we found our first lion's mane mushroom in the wild. We were living in the San Francisco Bay Area, working long days and absorbed in the busyness of life. One afternoon we were sitting in our front yard when something caught our eye over the fence — on the stump of a tree that had been cut down a few months earlier, right in the center of our neighbor's yard, was a large, white, fuzzy ball.

After a closer look we were certain: it was a lion's mane mushroom. We knocked on our neighbor's door and asked if we could have the mushroom growing on their dead tree stump. Confused but agreeable, they said yes — and we came home with our first wild-foraged lion's mane.

That moment sparked years of obsessive research, formulation, and eventually the creation of our Lion's Mane THINK Honey Tincture — now our best-selling product. And the more we learned about what this mushroom actually does in the human brain and body, the more we understood why.

What is lion's mane mushroom?

Lion's mane (Hericium erinaceus) is a large, white, shaggy-looking mushroom that grows on hardwood trees in forests across North America, Europe, and Asia. Its cascading white tendrils give it a striking resemblance to — you guessed it — a lion's mane. It is also known by its Latin name Hericium erinaceus, and has been used for centuries in traditional Chinese and Japanese medicine under names that translate roughly to "mountain priest mushroom."

Unlike most medicinal mushrooms that are known primarily for immune support, lion's mane has a unique and remarkable specialization: the brain and nervous system. It is the only natural substance known to stimulate the production of two critical neuroprotective compounds — Nerve Growth Factor (NGF) and Brain-Derived Neurotrophic Factor (BDNF) — that are essential for the health, growth, and repair of neurons.

This is what makes lion's mane genuinely unique in the natural wellness world. And it's why neuroscientists, biohackers, athletes, and everyday people are paying close attention.

The science: NGF and BDNF explained

To understand why lion's mane is so extraordinary, you need to understand two proteins: NGF and BDNF.

Nerve Growth Factor (NGF) is a protein that plays a critical role in the growth, maintenance, and survival of neurons — the cells that make up your brain and nervous system. NGF is essential for the development of new nerve cells and the protection of existing ones. As we age, NGF production naturally declines — a process that is closely associated with cognitive decline, memory loss, and neurodegenerative diseases like Alzheimer's and Parkinson's.

Brain-Derived Neurotrophic Factor (BDNF) is often described as "fertilizer for the brain." It supports the survival of existing neurons, encourages the growth of new neurons and synapses (a process called neuroplasticity), and plays a critical role in learning, memory formation, and mood regulation. Low BDNF levels are strongly associated with depression, anxiety, cognitive decline, and poor sleep.

Here's what makes lion's mane remarkable: its unique bioactive compounds — hericenones (found in the fruiting body) and erinacines (found in the mycelium) — have been shown in multiple studies to cross the blood-brain barrier and directly stimulate the production of both NGF and BDNF. No other natural substance has been shown to do this as effectively.

In practical terms, this means lion's mane actively supports the brain's ability to grow, repair, and protect itself — making it one of the most genuinely neuroprotective natural supplements available.

Top benefits of lion's mane mushroom

1. Lion's mane boosts memory and learning

By stimulating NGF and BDNF, lion's mane directly supports the neuroplasticity that underlies memory formation and learning. Neuroplasticity is the brain's ability to form new neural connections and reorganize existing ones — it's the biological mechanism through which we learn new skills, form memories, and adapt to new information.

Research has shown that lion's mane supplementation improves performance on memory and cognitive function tests, with particularly notable results in older adults. A landmark double-blind, placebo-controlled study published in Phytotherapy Research found that participants aged 50-80 who took lion's mane for 16 weeks showed significantly improved cognitive function scores compared to the placebo group — and that these improvements reversed when supplementation stopped, confirming the causal relationship.

For anyone looking to sharpen their memory, accelerate learning, or protect their cognitive function over the long term, lion's mane is one of the most evidence-backed natural tools available.

2. Lion's mane improves focus and mental clarity

Beyond memory, lion's mane is widely reported to improve focus, concentration, and mental clarity — often described by users as a "brain fog lift." This effect is consistent with its mechanism of action: by supporting healthy neural connections and the signaling pathways involved in executive function, lion's mane helps the brain operate more efficiently under cognitive demand.

Many of our customers — from students and professionals to parents and entrepreneurs — report that lion's mane is the first natural supplement where they've noticed a clear, tangible difference in their ability to focus and sustain attention. Our community consistently reports more mental clarity and sharper thinking after adding the THINK tincture to their daily routine.

3. Lion's mane protects against neurodegeneration

This may be lion's mane's most profound long-term benefit — and it's one that deserves far more attention than it gets.

Neurodegenerative diseases like Alzheimer's, Parkinson's, and dementia are characterized by the progressive loss of neurons and the degradation of neural connections. The decline in NGF production with age is a significant contributing factor — which is exactly why lion's mane's ability to stimulate NGF has generated so much excitement in the neuroscience community.

Multiple animal studies have shown that lion's mane can protect against the formation of amyloid plaques — the protein deposits associated with Alzheimer's disease — and may even help reverse existing neural damage. Human research is earlier stage but consistently promising. Several studies have found that lion's mane supplementation slows cognitive decline in older adults and supports the kind of neurological health that reduces dementia risk over the long term.

We take lion's mane every single day — not just for the immediate focus benefits, but as a long-term investment in our brain health. We've gifted it to parents, grandparents, and friends for the same reason. If you're in your 30s, 40s, or beyond, the time to start protecting your brain is before you notice problems — and lion's mane is one of the best tools available for doing so.

4. Lion's mane supports better sleep

Lion's mane for sleep is a less commonly discussed benefit — but the research is real and the mechanism makes sense.

NGF plays a role in regulating natural sleep-wake rhythms (circadian rhythms). By supporting healthy NGF levels, lion's mane helps maintain the biological timing systems that govern when you feel sleepy and when you feel awake. Research has also shown that lion's mane can decrease wakefulness during the active phase of sleep — meaning it helps you stay asleep rather than experiencing fragmented, restless sleep.

BDNF adds another dimension: it is closely correlated with reduced anxiety and improved mood, both of which are significant contributors to sleep quality. Many people who struggle to sleep due to an overactive, anxious mind find that lion's mane helps quiet the mental noise that keeps them awake — not through sedation, but through genuine nervous system support.

Our community frequently reports improved sleep quality as one of the first benefits they notice from daily lion's mane use — often within the first 1-2 weeks. For sleep support specifically, we recommend taking it in the evening or combining it with our Mushroom TRILOGY Tincture, which adds reishi's well-documented sleep and cortisol-regulating properties to the mix.

5. Lion's mane reduces anxiety and supports mood

Low BDNF levels are one of the most consistently identified biological markers of depression and anxiety. By stimulating BDNF production, lion's mane addresses one of the root neurological causes of mood dysregulation rather than simply masking symptoms.

A 2010 study published in Biomedical Research examined lion's mane's effects on mood in a group of menopausal women, finding significant reductions in anxiety and irritability scores after four weeks of supplementation compared to placebo. Other research has examined lion's mane's effects on the hippocampus — the brain region most involved in mood regulation and stress response — finding that its neuroprotective compounds support healthy hippocampal function and reduce the anxiety-related neural changes associated with chronic stress.

For anyone dealing with stress-driven anxiety, mood instability, or the emotional toll of a demanding life, lion's mane offers a genuinely evidence-based natural support — one that works with the brain's own chemistry rather than overriding it.

6. Lion's mane supports nerve regeneration and recovery

One of the most fascinating and underappreciated applications of lion's mane research is nerve regeneration. NGF is not just important for brain neurons — it plays a critical role in the repair and regeneration of peripheral nerves throughout the body. This has significant implications for anyone dealing with nerve damage from injury, diabetes, chemotherapy, or other conditions.

Animal studies have shown that lion's mane can accelerate the regeneration of damaged nerve tissue and improve functional recovery after nerve injury. This research is what originally drove our own deep interest in lion's mane — our son's brain injury journey led us to explore every natural tool available for neurological support and recovery, and lion's mane stood out above everything else we found.

For anyone navigating a head injury, concussion recovery, or peripheral nerve issues, lion's mane is worth serious consideration alongside conventional care. Always consult your healthcare provider for personalized guidance.

Lion's mane vs other mushrooms: what makes it unique

While all medicinal mushrooms have impressive properties, lion's mane occupies a distinct category of its own. Here's how it compares:

No other mushroom targets the brain and nervous system the way lion's mane does. For cognitive performance, brain protection, and nervous system support, it stands alone. That said, combining lion's mane with other mushrooms — as in our Mushroom TRILOGY — provides broader, more complete support across multiple body systems simultaneously.

How to take lion's mane for best results

As with all adaptogens, consistency is the key to getting the most from lion's mane. The neuroprotective and cognitive benefits build over time — most people notice initial improvements in focus and sleep within 1-2 weeks, with fuller cognitive benefits developing over 4-8 weeks of daily use.

• Sublingually — place 1mL under the tongue for fastest absorption directly into the bloodstream
• In morning coffee or tea — lion's mane pairs beautifully with coffee for a focused, productive morning without jitters
• In a smoothie — blends easily into any fruit or protein smoothie
• In the evening — for sleep and anxiety support, try taking it a few hours before bed

Recommended dose: 1mL once or twice daily, with or without food. Our THINK tincture contains 60 servings per bottle at 1mL per serving.

Frequently asked questions about lion's mane mushroom

How long does lion's mane take to work?

Many people notice initial improvements in focus and mental clarity within the first 1-2 weeks. Improved sleep quality is often one of the first benefits reported. Fuller cognitive benefits — sharper memory, improved learning, reduced brain fog — typically develop over 4-8 weeks of consistent daily use. Neuroprotective benefits build over months and years of consistent use.

Can I take lion's mane every day?

Yes — and daily consistency is essential for getting the full cognitive and neuroprotective benefits. Lion's mane is safe and well-tolerated for long-term daily use by most people. As with any supplement, consult your physician if you are pregnant, nursing, have a medical condition, or are taking medications.

Is lion's mane good for anxiety?

Research suggests yes — by stimulating BDNF production and supporting healthy hippocampal function, lion's mane addresses some of the neurological root causes of anxiety. Studies have shown reductions in anxiety and irritability scores after regular lion's mane supplementation. It is not a replacement for professional mental health care, but many people find it a valuable natural support alongside other wellness practices.

Can lion's mane help with brain fog?

This is one of the most commonly reported benefits among our customers. Brain fog — that feeling of mental cloudiness, slow thinking, and difficulty concentrating — is often related to suboptimal neural signaling and inflammation. Lion's mane addresses both through its NGF-stimulating and anti-inflammatory properties. Many people describe a noticeable "lift" in mental clarity within the first few weeks of daily use.

What is the best way to take lion's mane?

A properly extracted liquid tincture taken sublingually (under the tongue) provides the fastest and most complete absorption. Raw or powdered lion's mane is significantly less bioavailable because the beneficial compounds are locked behind chitin cell walls that the human digestive system cannot break down efficiently. Our THINK tincture uses a triple extraction process — hot water, organic alcohol, and ultrasonication — to ensure you're getting the full spectrum of bioavailable compounds in every dose.

Is lion's mane good for older adults?

Particularly so. The decline in NGF production with age is one of the key drivers of age-related cognitive decline. Several studies have specifically examined lion's mane in older adults, finding significant improvements in cognitive function scores and promising evidence for slowing the progression of memory loss. Starting lion's mane supplementation earlier — before noticeable decline begins — is ideal, but research suggests meaningful benefits are possible at any age.

Can lion's mane be taken with other mushrooms?

Absolutely — and combining it with reishi and chaga (as in our TRILOGY tincture) provides broader support across brain health, immune function, stress resilience, and sleep simultaneously. There are no known negative interactions between medicinal mushrooms.
