The Stamets Stack: Lion's Mane, Psilocybin, and Niacin Explained

Mycologist Paul Stamets popularised a specific microdosing combination — psilocybin, lion's mane, and niacin. Here's the science behind the stack and whether it actually works.

Quick Answer: The Stamets Stack is a microdosing protocol combining psilocybin, Lion's Mane mushroom (Hericium erinaceus), and niacin (Vitamin B3), popularized by mycologist Paul Stamets. This synergistic combination is hypothesized to enhance neuroplasticity, cognitive function, and mood by leveraging psilocybin's ability to create neuroplastic "windows," Lion's Mane's stimulation of Nerve Growth Factor (NGF), and niacin's role in improving blood flow and neuroprotection. While anecdotal evidence and observational studies suggest benefits for mental health and cognitive enhancement, formal clinical trials on the stack as a whole are still emerging.

The Stamets Stack: Lion's Mane, Psilocybin, and Niacin Explained

In 2019, renowned mycologist and psychedelic researcher Paul Stamets introduced a microdosing protocol that has since gained significant traction within the wellness and scientific communities: the combination of psilocybin mushrooms with Lion's Mane mushroom (Hericium erinaceus) and niacin (vitamin B3). This unique blend, dubbed the "Stamets Stack," is rooted in a scientifically plausible hypothesis suggesting a synergistic effect on brain health and cognitive function. The rationale extends beyond simple supplementation, proposing a sophisticated interplay between these three components to foster neuroplasticity and overall mental well-being.

Understanding the Components of the Stamets Stack

Psilocybin: The Neuroplasticity Catalyst

Psilocybin, the primary psychoactive compound found in certain mushrooms, is a potent inducer of neuroplasticity. Its mechanism involves modulating serotonin 5-HT2A receptors, which in turn influences the expression of brain-derived neurotrophic factor (BDNF) and TrkB receptor signaling [Grieco et al., 2022]. This process facilitates the growth of new synaptic connections and enhances the brain's ability to adapt and reorganize itself. These neuroplastic changes are considered fundamental to psilocybin's observed antidepressant, anxiolytic, and cognitive-enhancing effects [Zhao et al., 2024]. In the context of the Stamets Stack, psilocybin is administered at a sub-perceptual microdose, typically ranging from 0.1 to 0.3 grams of dried mushroom equivalent, ensuring therapeutic benefits without inducing a full psychedelic experience.

Lion's Mane Mushroom: Supporting Neuronal Growth

Lion's Mane mushroom (Hericium erinaceus) stands out as the most extensively researched non-psychedelic mushroom for its profound cognitive benefits. Its active compounds, particularly hericenones and erinacines, are known to stimulate the production of Nerve Growth Factor (NGF) [Contato et al., 2025]. NGF is a crucial protein essential for the growth, maintenance, and survival of neurons, playing a vital role in neurogenesis and neuronal repair [News-Medical, 2023]. The hippocampus and prefrontal cortex, brain regions critically involved in memory, learning, mood regulation, and often affected by conditions like depression, anxiety, and age-related cognitive decline, are particularly responsive to NGF stimulation [Alzdiscovery.org, 2025]. Stamets' hypothesis posits that Lion's Mane complements psilocybin by providing the necessary NGF to consolidate and maintain the new neural connections initiated by psilocybin, thereby potentially leading to more durable and significant neuroplastic changes than either compound could achieve alone.

Niacin (Vitamin B3): Enhancing Delivery and Neuroprotection

Niacin, or vitamin B3, is included in the Stamets Stack for its multifaceted contributions. Firstly, as a vasodilator, niacin increases blood flow throughout the body, including the brain and peripheral nervous system [Stamets, 2019]. This enhanced circulation is theorized to improve the delivery and bioavailability of psilocybin and Lion's Mane compounds to neural tissues, maximizing their therapeutic potential. Secondly, niacin possesses inherent neuroprotective properties and is a precursor to NAD+ (nicotinamide adenine dinucleotide), a coenzyme vital for cellular energy metabolism, DNA repair, and overall cellular health [Stamets, 2019]. The characteristic "niacin flush"—a temporary skin redness and tingling sensation—is often considered by some practitioners as an indicator of increased peripheral blood flow, though non-flush niacin forms are also used to mitigate this effect.

The Synergistic Hypothesis: How the Stack Aims to Work

The core principle of the Stamets Stack lies in the proposed synergy between its components. Psilocybin is believed to create a "neuroplastic window" by upregulating BDNF and promoting the formation of new neural pathways. During this period of heightened brain plasticity, Lion's Mane, with its NGF-stimulating properties, is thought to provide the building blocks and support necessary for these new connections to strengthen and become more permanent. Niacin then acts as a delivery enhancer, ensuring that both psilocybin and Lion's Mane compounds reach their targets efficiently, while also contributing its own neuroprotective benefits. This multi-pronged approach aims to optimize brain function, enhance cognitive abilities, and improve emotional resilience.

Scientific Evidence and Observational Findings

While the theoretical framework of the Stamets Stack is compelling, formal clinical trials specifically investigating the combined effects of all three components are still limited. However, research on the individual components and observational studies on microdosing practices provide valuable insights.

Evidence for Individual Components:

  • Psilocybin: Numerous studies have demonstrated psilocybin's ability to induce neuroplasticity and produce rapid, sustained antidepressant-like effects [Zhao et al., 2024; Du et al., 2023]. Its potential in treating depression, anxiety, and PTSD is a growing area of research [Rootman et al., 2022].
  • Lion's Mane: Preclinical and some human studies suggest Lion's Mane can improve cognitive function, reduce stress, and promote neurogenesis by increasing NGF levels [Docherty et al., 2023; Contato et al., 2025].
  • Niacin: Beyond its role in vasodilation, niacin has been studied for its neuroprotective effects and its involvement in cellular energy pathways [Stamets, 2019].

Observational Studies on the Stamets Stack:

A naturalistic, observational study published in Scientific Reports followed psilocybin microdosers and non-microdosing comparators for approximately 30 days. The study found small- to medium-sized improvements in mood and mental health among microdosers. Importantly, among older microdosers, combining psilocybin with Lion's Mane and niacin was associated with psychomotor improvements relative to psilocybin alone or psilocybin and Lion's Mane without niacin [Rootman et al., 2022]. Another cross-sectional survey of over 4000 microdosers found that over 50% of psilocybin microdosers combined psilocybin with diverse substances, with Lion's Mane and niacin being prevalent additions [Rootman et al., 2021]. These findings, while observational and subject to selection bias, suggest potential benefits and highlight the need for further rigorous research.

Dosing and Protocol Recommendations

Paul Stamets recommends a specific microdosing schedule for the Stamets Stack: a 4-days-on, 3-days-off regimen, differing from other common protocols like the Fadiman protocol (1-on, 2-off). Typical dosages are:

  • Psilocybin Mushroom: 0.1–0.3 grams (dried equivalent)
  • Lion's Mane Extract: 50–200 mg
  • Niacin: 100–200 mg

The niacin is typically taken 20–30 minutes after the psilocybin and Lion's Mane to allow the niacin flush to coincide with the peak absorption of the other compounds, theoretically enhancing their delivery to the brain.

Potential Benefits and Applications

The proposed benefits of the Stamets Stack are wide-ranging, primarily focusing on cognitive enhancement and mental health support. Users and proponents suggest improvements in:

  • Neuroplasticity: Enhanced ability of the brain to form new connections and adapt.
  • Cognitive Function: Improved focus, clarity, creativity, and problem-solving abilities.

The Science Behind Neuroplasticity and the Stamets Stack

Synaptic Plasticity and BDNF

Neuroplasticity, the brain's ability to reorganize itself by forming new neural connections throughout life, is a fundamental process underlying learning, memory, and recovery from brain injury. At the cellular level, this involves synaptic plasticity—the strengthening or weakening of connections between neurons. Brain-Derived Neurotrophic Factor (BDNF) is a key protein that plays a crucial role in promoting the growth, differentiation, and survival of neurons, and in enhancing synaptic plasticity. Psilocybin, even at microdoses, has been shown to rapidly increase BDNF levels and activate its receptor, TrkB, leading to a rapid increase in dendritic spine density [Zhao et al., 2024]. These dendritic spines are critical for receiving synaptic inputs, and their increased density and functionality are directly linked to enhanced learning and memory capabilities. The Stamets Stack leverages this effect, with psilocybin opening a "window of plasticity" during which the brain is more receptive to forming new connections.

Myelination and Cognitive Speed

Beyond synaptic connections, the efficiency of neural communication is heavily dependent on myelination—the process by which nerve fibers are insulated with a fatty substance called myelin. Myelin acts like insulation on an electrical wire, allowing electrical impulses to travel more quickly and efficiently along neurons. Demylination is associated with various neurological disorders and cognitive decline. Lion's Mane mushroom, with its unique compounds hericenones and erinacines, has been shown to promote myelination [News-Medical, 2023]. By supporting the health and integrity of myelin sheaths, Lion's Mane contributes to faster and more efficient neural processing, which translates to improved cognitive speed, reaction time, and overall mental acuity. Niacin's role in enhancing blood flow further supports the delivery of nutrients and oxygen necessary for these complex neurobiological processes, creating an optimal environment for brain health and function.

Future research should investigate how these lifestyle variables modulate the effects of the Stamets Stack, potentially identifying optimal lifestyle interventions that can amplify its benefits. A holistic understanding of these interactions will enable individuals to integrate the Stamets Stack into a comprehensive wellness strategy, fostering sustained improvements in cognitive function and mental health. This integrated approach underscores the importance of viewing health as a complex interplay of biological, psychological, and environmental factors.

The Stamets Stack and Mental Well-being: A Deeper Look

Addressing Depression and Anxiety

The potential of the Stamets Stack in addressing symptoms of depression and anxiety is a significant area of interest. Psilocybin, even at microdoses, has been shown to reduce activity in the default mode network (DMN), a brain network associated with self-referential thought and rumination, which is often overactive in individuals with depression [Carhart-Harris & Goodwin, 2017]. By dampening DMN activity, psilocybin can help individuals break free from negative thought loops and foster a more open and flexible mindset. Lion's Mane, with its anti-inflammatory and neuroprotective properties, further supports mental well-being by mitigating the impact of chronic stress on brain health. The combination offers a multi-pronged approach to mental health, targeting both the psychological and neurobiological underpinnings of depression and anxiety. While not a substitute for professional medical care, many individuals report significant improvements in mood, reduced anxiety, and an enhanced sense of emotional balance when incorporating the Stamets Stack into their wellness routine.

Enhancing Focus and Productivity

In today's fast-paced world, maintaining focus and productivity can be a challenge. The Stamets Stack is gaining popularity among individuals seeking to enhance these cognitive functions. Users often report improved concentration, sustained attention, and a greater ability to enter and maintain a state of flow. This is attributed to psilocybin's ability to reduce mental chatter and enhance cognitive flexibility, allowing the brain to allocate resources more efficiently. Lion's Mane further supports this by promoting overall brain health and reducing brain fog, leading to clearer thinking. The synergistic effect of the stack can help individuals to be more present, engaged, and effective in their daily tasks, making it a valuable tool for optimizing performance in various professional and personal endeavors.
