Lion's Mane Research
Explore what current studies say about Lion's Mane, where the evidence is strongest, and where more research is still needed.
Why Scientists Are Interested in Lion's Mane
Lion's Mane (Hericium erinaceus) has been enjoyed as both a food and a traditional wellness ingredient for centuries.
Today, scientific interest centers on the mushroom's naturally occurring compounds and how they interact with the body. Researchers continue exploring how these compounds may influence cognitive function, immune health, healthy aging, and other areas of wellness.
Much of the excitement surrounding Lion's Mane comes from this ongoing research—but it's important to remember that scientific understanding develops one study at a time.
Key Terms
Functional Mushroom
Lion's Mane is considered a functional mushroom—a mushroom enjoyed as a food while also being studied for naturally occurring compounds that may support overall wellness.
Nootropic (noo-uh-TROP-ik)
Lion's Mane is also commonly described as a nootropic, a broad term used for substances being studied for their potential to support memory, focus, learning, and other aspects of cognitive function.
Being called a nootropic doesn't mean those benefits are proven—it means they're active areas of scientific research.
Adaptogen (uh-DAP-tuh-jen)
You may also see Lion's Mane described as an adaptogen, a term generally used for substances that may help the body adapt to physical or mental stress.
Some researchers and herbal practitioners include Lion's Mane among adaptogenic mushrooms, while others reserve the term for mushrooms such as Reishi and Cordyceps.
Definitions vary, which is why you'll see Lion's Mane described both ways.
The Compounds Researchers Are Studying
Scientists aren't studying just one ingredient within Lion's Mane. They're investigating dozens of naturally occurring compounds, several of which have become particular areas of interest.
Beta-Glucans
Beta-glucans are naturally occurring polysaccharides found in the cell walls of mushrooms.
Researchers have studied beta-glucans for decades because of their interaction with the immune system and their role in overall wellness.
Hericenones (hair-ISS-uh-nohns)
Hericenones are naturally occurring compounds found primarily in the fruiting body of Lion's Mane.
Researchers continue studying these compounds because of their potential relationship with nerve growth factor (NGF)—a naturally occurring protein involved in the growth, maintenance, and survival of nerve cells.
Erinacines (air-IN-uh-seens)
Erinacines are a related family of compounds found primarily in Lion's Mane mycelium, the underground network of thread-like structures that supports mushroom growth.
Like hericenones, erinacines are being studied for their biological activity and their potential relationship with nerve growth factor.
Researchers continue investigating both groups of compounds to better understand how they function individually—and together.
What Those Compounds May Mean
Current research has explored Lion's Mane in several areas, including:
Cognitive Function
Researchers continue studying Lion's Mane for its potential role in supporting healthy cognitive function, memory, learning, and mental clarity.
Several small human studies have produced encouraging findings, but larger, well-controlled clinical trials are still needed.
Healthy Aging
Scientists are also investigating Lion's Mane as part of broader research into healthy aging and maintaining normal brain function over time.
This remains an active area of research.
Mood and Emotional Well-Being
Some early studies have examined whether Lion's Mane may play a role in supporting emotional well-being.
While initial findings have generated interest, researchers caution that additional human studies are necessary before firm conclusions can be drawn.
Immune Function
Because mushrooms naturally contain beta-glucans, researchers continue studying Lion's Mane for its interaction with the immune system and its role in supporting normal immune function.
Inflammation
Researchers are also investigating how naturally occurring compounds found in Lion's Mane may influence normal inflammatory pathways.
Like many areas of mushroom research, this work is ongoing and continues to evolve.
From Compound to Clinical Trial
Scientific discovery rarely happens all at once.
Researchers often begin by identifying naturally occurring compounds within a mushroom. Laboratory studies help scientists understand how those compounds behave. Promising findings may lead to animal studies and, eventually, carefully designed human clinical trials.
Each study adds another piece to the puzzle. No single study tells the whole story.
What We Know
Research into Lion's Mane has expanded dramatically over the past decade.
Scientists have identified numerous naturally occurring compounds within the mushroom and continue investigating how they interact with the brain, immune system, and other biological pathways.
Several small human studies have reported encouraging findings related to cognitive function and mood, while laboratory and animal studies continue exploring the mushroom's broader biological activity.
The research is promising. It is also still developing.
What We Don't Know (Yet)
Science is a process.
Researchers continue studying important questions, including:
- Which naturally occurring compounds contribute most to observed effects?
- How much Lion's Mane is ideal for different applications?
- How long should it be consumed?
- How do whole mushrooms compare with concentrated extracts?
- Which populations may benefit most?
These are exactly the kinds of questions ongoing clinical research hopes to answer.
At Forge, we think it's important to be honest about that.
Promising research is exciting.
It's not the same thing as settled science.
Why We Chose Whole Mushrooms
Our decision to use whole Colorado-grown Lion's Mane wasn't based on one single study.
It was based on our overall philosophy and personal experience.
We believe wellness products should be built with real ingredients, meaningful potency, transparent labeling, and honest value.
We were also drawn to the fact that most published research investigates the mushroom itself and its naturally occurring compounds—not a proprietary blend designed by a marketing department.
That's the same philosophy that guided Forge Hemp from the beginning.
Different ingredients. Same Forge philosophy.
Want to Read the Research Yourself?
We encourage it.
One of the comprehensive reviews we found particularly helpful is:
Published in 2025 in the journal Foods.
It provides an excellent overview of current laboratory, animal, and human research while also discussing the limitations and areas where more evidence is still needed.
How We Read Research
Not all scientific studies answer the same questions.
Throughout our educational materials, we prioritize:
- Human clinical studies whenever available
- Systematic reviews and meta-analyses
- Peer-reviewed journals
- Transparent discussion of study limitations
When the evidence is strong, we'll tell you. When it's still emerging, we'll tell you that too.
Our Approach to Wellness
At Forge, we don't chase trends. We don't make exaggerated promises. And we don't believe one study tells the whole story.
Instead, we follow the research, continue learning, and build products we proudly use ourselves and confidently recommend to family and friends.
That's been our philosophy since 2019.
