Lion’s mane (Hericium erinaceus) is an edible mushroom with a long history in traditional East Asian medicine. It’s been used for centuries — primarily in China and Japan — to support digestive and neurological health. Today it’s most commonly sold as a powdered extract in capsules or tinctures, and it’s become one of the more heavily marketed supplements in the nootropic — or “brain-boosting” — category.

The part that’s genuinely interesting, scientifically, is what’s inside it. Lion’s mane contains two groups of bioactive compounds — hericenones (from the fruiting body) and erinacines (from the mycelium, or root structure). Both have been shown, in laboratory and animal studies, to stimulate the production of Nerve Growth Factor (NGF) — a protein involved in the growth, maintenance, and survival of neurons ^[1]. Importantly, erinacines are small enough in molecular structure to cross the blood-brain barrier — something NGF itself cannot do when administered externally ^{[2, 3]}.

That’s not nothing. But it’s also a long way from a clinical treatment.

Complex trauma — particularly trauma experienced early in life — has well-documented effects on brain development. The hippocampus, a region central to memory, contextual learning, and the regulation of threat responses, is one of the areas most consistently affected. Research has found reduced hippocampal volume associated with childhood maltreatment, with the strongest effects seen in the dentate gyrus and CA3 subfields — precisely the areas where adult neurogenesis (brain growth) occurs ^[4]. The underlying process involves suppression of neurotrophin expression and impaired neuron regeneration under chronic stress conditions ^[5].

This is where lion’s mane becomes theoretically relevant. Erinacine A has been shown in animal models to elevate NGF expression specifically in the hippocampus — not broadly across the brain, but in this particular region ^[6]. Animal studies have also found increased hippocampal neurogenesis following lion’s mane administration ^[7]. In principle, then, these compounds could support some of the neuroplasticity conditions that trauma recovery depends on.

No clinical trials have tested lion’s mane in trauma populations. The human research that exists — mostly small studies in healthy adults and older people with mild cognitive concerns — shows modest and inconsistent effects. The leap from “may support hippocampal neurogenesis in rodents” to “helps people recover from complex trauma” is a large one, and marketing language tends to obscure that gap rather than acknowledge it, in order to gain your dollar.

If we set aside the overclaiming, an objective look at the available evidence suggests lion’s mane extract may offer the following:

• Modest cognitive support — one randomised, double-blind, placebo-controlled pilot study found that a single 1.8g dose improved processing speed in healthy young adults, and 28 days of supplementation showed a trend toward reduced subjective stress ^[8].
• Mood regulation — a small, uncontrolled pilot study found improvements in anxiety and depression measures, alongside increased circulating BDNF levels ^[9].
• Sleep quality — noted in multiple reviews as a potential benefit, and relevant given how central sleep disruption is to trauma presentations ^[10].

These are not trivial things for someone living with complex trauma. They’re also not a treatment, and they won’t do what therapy does.

My assessment is this: lion’s mane may help create some of the neurobiological conditions that support recovery — alongside what we know more confidently, like regular exercise, adequate sleep, and meaningful therapeutic work. It is not a substitute for any of those.

The research that exists has generally used doses of 1–3 grams per day, with studies up to 5 grams per day finding no significant adverse effects. It appears well tolerated in most people, though rare allergic reactions have been documented, and anyone taking prescription medication should check with their GP or prescriber before starting, as formal drug interaction data in humans is limited ^[11].

A few things worth knowing before you buy:

People who live with complex trauma often spend years searching for something that will finally make the difference. That’s not a character flaw — it’s a reasonable response to suffering that has often been minimised or misunderstood. It’s also evidence of a drive to support yourself and to give yourself the best chance into the future. But it does mean the wellness industry has a ready and motivated audience, and some of what gets marketed into that space deserves more scrutiny than it receives.

Lion’s mane is not the worst of that. It’s a real food, with a real history, and some genuinely interesting — if preliminary — science behind it. It’s unlikely to harm you, and it may offer modest support. The choice of whether to try it is individual, and it’s a reasonable one to make.

What I’d gently caution against is letting the hope it represents substitute for the harder, slower work of trauma recovery. That work is irreplaceable. Anything that supports it is worth considering. Anything that promises to replace it deserves scepticism.

If trauma began during the foundational years of development — before you had a formed sense of self, before you had language to make sense of your experiences, or before you had any sustained experience of safety — your nervous system was still being built as the trauma occurred. The responses your body learned weren't layered on top of something healthy. They were wired in as the baseline.

• No clear memories of feeling truly safe
• Trusting others or feeling calm in your body feels foreign — not lost, but never quite learned
• A sense of always having been "different" from other people
• Emotions that feel overwhelming or completely shut off
• Difficulty knowing what you need or want

• Learning safety and trust for the first time — not "getting it back"
• Building basic emotional regulation skills from the ground up
• Discovering what your authentic self feels like
• Learning that relationships can be safe (this often takes longer)
• Developing a sense of your own worth and identity

Why it's different: Your brain was still forming when trauma occurred, so survival responses got wired in as "normal." Therapy often focuses on building new neural pathways — creating patterns of safety and connection that weren't able to form in the first place. This isn't about fixing something broken; it's about building something new.

If trauma happened after you'd developed a more stable sense of self — after you had some experience of safety, connection, and who you were — the disruption lands differently. There's something that was working, and then something changed it.

• Remembering what "normal" felt like before
• Feeling like you "lost yourself" or became someone different
• A clear "before and after" in your life
• Frustration that you "should" be able to get back to how you were

• Restoring your nervous system's capacity for safety
• Processing specific traumatic events and their impact
• Reconnecting with parts of yourself that existed before
• Rebuilding trust in yourself and others
• Therapy often focuses on working through what was disrupted and returning to patterns that existed before

Why it's different: Your brain had already formed basic templates for safety and connection. Trauma disrupted these systems, but the foundation was there. Healing can sometimes involve "remembering" what safety felt like — finding your way back to something real, even if it feels distant right now.

These categories aren't a clean divide. Development doesn't work on a strict timeline, and trauma often doesn't either. Some people experienced early trauma and also had later trauma layer on top. Some had protective relationships early on that softened the impact, even if trauma started young. Others had later trauma that was severe enough to shake foundational parts of themselves.

If you find yourself relating to both descriptions, that makes sense. You don't have to fit neatly into one category to find this framework useful.

One trap worth naming: people with early trauma sometimes minimise their experience because they can't clearly remember it, or because it just felt like "normal life." And people with later trauma sometimes feel guilty, as if their pain is less valid because they did have a foundation at some point. Neither of those comparisons is fair to yourself.

A trauma-informed therapist will understand these differences and tailor their approach accordingly. They won't expect you to have skills or memories you never had the chance to develop, and they won't rush you to "get back" to somewhere you might never have been.

Recovery isn't about going back to who you were before trauma happened. It's about discovering your capacity for safety, connection, and being present in your own life. Your nervous system has a remarkable capacity to grow and change, no matter when trauma occurred. The brain retains plasticity throughout life — which means healing isn't just possible in theory.

Sometimes it just needs the right support and understanding to learn — or remember — what safety feels like.

Attachment styles develop in childhood, shaped by our early experiences with caregivers — specifically, how they responded when we were scared, hurt, or in need.² From those early interactions, we build what researchers call internal working models: deeply held templates for how relationships work, whether we are loveable, and whether others can be trusted to be there for us.

The important thing to understand is that these patterns were not mistakes. They were adaptations — ways your nervous system learned to stay safe in the relationships you depended on. The difficulty is that they tend to follow us into adulthood long after those original relationships have ended, quietly shaping who we choose, how we behave, and why things keep going wrong in ways that feel familiar and bewildering at the same time.

Securely attached people tend to feel comfortable with both closeness and independence. Secure attachment typically develops when caregivers were emotionally attuned and consistently responsive — not perfect, but reliably present.² People with this style tend to:

• Trust others without losing themselves
• Express needs and feelings openly and respectfully
• Move through conflict without the relationship feeling like it's on the line
• Feel comfortable with both togetherness and time apart

It's worth noting: many people who didn't have this foundation in childhood can develop what researchers call earned secure attachment — a more grounded way of relating built through therapy, meaningful relationships, and sustained self-reflection.³ This is genuinely possible, and it's often what the therapeutic journey is pointing toward.

If you have an anxious attachment style, closeness is what you long for — but it's also terrifying. You may find yourself chronically worried about whether your partner really loves you, whether they're about to leave, whether you've said something wrong. The reassurance comes, but it doesn't settle. You're scanning for signs of withdrawal even when things are fine.^5,6

This style often develops when caregiving was inconsistent — sometimes warm and responsive, sometimes not — leaving the child in a state of constant uncertainty about whether their needs would be met.⁷ The nervous system learned: I have to stay alert. I have to work harder. Love is something that can disappear.

Behaviours that may show up:

• Over-texting or obsessing over a partner's responses
• Preoccupation with a partner's mood or tone
• Difficulty tolerating distance or silence
• Emotional outbursts followed by shame
• Over-accommodating to avoid conflict

The exhausting loop: seek reassurance → feel briefly settled → anxiety returns → seek again.

People with avoidant attachment often pride themselves on self-sufficiency — and genuinely believe they don't need much from others. But beneath that is something more complicated: emotional closeness was learned to be unsafe, so the nervous system now treats it as a threat.^8,9 When a relationship deepens, something tightens. The urge to withdraw kicks in.

This style often develops when caregivers were emotionally distant or rejecting — not necessarily cruel, but unavailable in the ways that mattered. The child learned to suppress their needs rather than risk the pain of reaching out and finding no one there. I'll manage alone. Needing people only leads to disappointment.

Behaviours that may show up:

• Shutting down or withdrawing during conflict
• Difficulty expressing feelings or needs
• Ending relationships when they start to feel serious
• Distrusting others' intentions or motives
• Feeling suffocated by a partner's needs — even when those needs are reasonable

This is perhaps the most painful pattern to live with — and the most important to approach with compassion. If you recognise it in yourself, please read this gently: this is not a character flaw. It is a survival response to an impossible situation.

Disorganised attachment develops when the person who was meant to be your source of safety was also frightening or unpredictable.^10,11 This creates a fundamental bind that the child's nervous system cannot resolve: I need you to survive, and you are the source of my fear. The result is an attachment system that never gets to organise itself around a coherent strategy.

In adult relationships, this often looks like desperately wanting connection while simultaneously pushing it away — craving closeness but feeling unsafe the moment it arrives. The internal world is one of deep conflict: I want love, but I don't trust it. I need you close. I need you to go away.

Behaviours that may show up:

• Explosive arguments followed by withdrawal and shame
• Sabotaging relationships that start to feel safe or close
• Intense fear of abandonment alongside an inability to tolerate closeness
• Difficulty regulating emotions
• Deep struggles with self-worth and self-blame

This pattern is strongly associated with early trauma — which means it deserves not judgment, but care.

Probably not — and that's completely normal. Most people recognise themselves in more than one style. You might be predominantly anxious in romantic relationships but avoidant with friends. You might have grown up mostly secure but experienced trauma later that shifted things. Attachment is not a fixed category you're assigned at birth; it's a living pattern that varies across relationships, contexts, and time.

What's more useful than finding your "type" is starting to notice when a familiar pattern kicks in — that particular tightening in your chest when a message goes unanswered, the urge to pull back just as someone gets close, the sense that love is something you have to earn or can't quite trust. That noticing is where change begins.

These patterns were adaptive. They helped you survive emotionally. But if you're reading this, you likely already know that they're now costing you something — the closeness, the stability, the kind of love that doesn't leave you exhausted or alone.

Therapy offers a particular kind of space for this work.¹² Not just insight — though understanding your pattern matters — but the lived experience of a relationship where new things are possible. Where you can notice the old pull to withdraw or cling, and choose something different. Where the nervous system slowly learns that it doesn't have to work so hard. Where you begin to respond rather than react.

That is the work. And it is quiet, and gradual, and genuinely possible.

When we are in a state of fear, our perception narrows. The brain, working exactly as it was designed to, scans for threat — and finds it everywhere. Positives fade into the background. Nuance disappears. What remains is a world that looks overwhelming, dangerous, and hostile.

This isn't weakness or irrationality. It's biology. The part of your nervous system designed for survival has taken over, and in doing so, it has quite literally changed what you are able to perceive. A neutral comment becomes a slight. A quiet moment becomes the calm before the storm. Safety feels like something that exists for other people.

Here's what's important to understand: the nervous system that activates under fear is designed for emergencies. It's brilliant at getting you out of immediate danger. It is not, however, designed for navigating the complex terrain of relationships, decisions, careers, or daily life.

When this survival system is running the show, you're not thinking from your values. You're not making decisions from your preferences or your wisdom. You are reacting — to perceived threat. And reactions driven by fear rarely take us where we actually want to go.

Humans are meaning-making creatures. When things go wrong — even when they've gone wrong because fear was steering — we don't just notice the outcome. We internalise it. We turn it into a story about who we are.

And here is where fear becomes truly entrenched. Because once we've made that meaning, the fear doesn't need a new trigger — it has evidence now. The loop closes. Fear shapes perception, perception shapes action, action shapes outcome, outcome confirms the story, and the story feeds the fear.

Over time, this loop can leave us in one of two places: hiding — contracted, withdrawn, unable to engage with life fully — or in angry defence, warding off a world that feels relentlessly threatening.

Neither is living. Both are exhausting.

The good news is that this cycle, as powerful as it feels, is not who you are. It is a pattern — one your nervous system learned, often for very good reasons, often a long time ago. And patterns can change.

Understanding how fear shapes perception is the first step. Not to dismiss the fear, but to recognise it for what it is — a signal, not a truth. When you can begin to see fear as something happening in you rather than a reliable report about the world, something shifts. Slowly, you begin to act from something deeper than threat. You begin to act from your values, your preferences, your genuine self.

That is when life starts to open up again.
