These Functional Mushrooms Aren’t New
(America Is Just Catching Up)
Functional mushrooms have been a staple throughout Eastern wellness culture for centuries. But the average American is just now learning about them. Here’s why, and what you need to know.

The History
Why America Fell in Love with Caffeine
If functional mushrooms have been around for centuries, why are most Americans only hearing about them now?
To answer that question, it helps to understand America’s long relationship with caffeine, and how it’s become ingrained in our culture.
Coffee arrived in Europe during the 1600s and quickly became associated with commerce, productivity, and the Enlightenment. Coffeehouses became gathering places for merchants, scientists, politicians, and writers. Some historians even nicknamed them “Penny Universities” because they became hubs for exchanging ideas.
When Europeans colonized North America, they brought coffee with them.
By the Industrial Revolution (the late 1700s through 1800s), caffeine had become almost synonymous with work. Long factory shifts, expanding business culture, and eventually office culture all reinforced the idea that productivity came from stimulation.

Caffeine Culture Visual
Fast forward another century, and caffeine had become a norm in American culture:
- ☕ coffee became a morning ritual
- ☕ soda added caffeine to everyday beverages
- ☕ energy drinks emerged in the late 20th century
- ☕ pre-workouts exploded in fitness
- ☕ highly concentrated stimulants became normalized
The American mindset became: Tired? Drink more caffeine.
Eastern Traditions
Traditional Mushrooms Visual
Meanwhile in Eastern Traditions...
Across China and other parts of Asia, functional mushrooms like Lion’s Mane, as well as Cordyceps and Reishi, had already been used for centuries. Not because people were trying to “biohack,” and not because they wanted a quick jolt of energy.
But because functional mushrooms like those named above had been traditionally valued for their properties that support vitality, resilience, and overall well-being.
Only in the last decade or two have these mushrooms become mainstream in Western wellness, helped by growing scientific interest and the popularity of biohacking. But here’s the thing: clearly biohackers didn’t discover functional mushrooms.
However, they did do this…

The Paradigm Shift
Clean Energy Lifestyle
Biohackers Didn’t Discover Functional Mushrooms.
(But They Changed How the West Thinks About Stimulation.)
Clean Energy Lifestyle
While much of America continued asking, “How can I get more energy?” biohackers started asking a very different question:
How can I support my brain instead of simply stimulating it?
This one question changed everything. Rather than chasing bigger spikes of stimulation, people started looking for steadier focus, cleaner energy, and long-term performance. That subtle redirection has helped bring functional mushrooms into the mainstream.
This meaningful paradigm shift means more average Americans are turning towards functional mushrooms. And this shift has led many people to discover three functional mushrooms in particular:
- 🍄 Lion’s Mane for focus, memory, and cognitive function
- 🍄 Cordyceps for clean, calm energy and stamina
- 🍄 Reishi for stress and sleep support
What functional mushrooms aren’t associated with (unlike caffeine):
- ❌ jitters
- ❌ crash
- ❌ dependence

The 2 Problems with Most Mushroom Supplements
The two major issues with functional mushrooms and their emergence in the West have been:
1
Absorption
2
Lack of ingredient integrity
Problem 1: Absorption
First, let’s explore absorption. The majority of mushroom supplements come in formats like:
Pills
Capsules
Powders
Drinks
Gummies
Soft chews
All of these formats must go through the digestive system to be absorbed. Inherently, not the worst thing in the world. But it’s also not the only option anymore, and may not be the best. Now, thanks to new technology, functional mushrooms can be absorbed buccally (meaning: through the gums and lining of the mouth, which bypasses compromise during digestion). But more on that shortly.

Problem 2: Ingredient Integrity
The second challenge came with popularity. As functional mushrooms became more mainstream, hundreds of brands rushed into the market. Some prioritized premium ingredients and transparent formulations. Others looked for ways to reduce manufacturing costs.
So when looking for a functional mushrooms product, always check the Supplement Facts Panel and do your research. An important question to ask is this:
What part of the mushroom is being used in the formula? Is it fruiting bodies (the main part of the mushrooms) or is it mycelium (the root-like structure of the mushrooms)?
Fruiting bodies are where most of the beneficial nutrients are, but many manufacturers will grow mycelium-on-grain. What does this mean?
“On-grain” indicates it was commercially grown using a grain, such as:
Oats
Rice
Sorghum
Millet
So the mycelium grows through the grain. The problem? Many manufacturers harvest and dry the entire thing: Mycelium + grain, then they grind it into a powder and sell it as a mushroom supplement. So when people buy “1,000mg Lion’s Mane,” they may actually be getting a meaningful amount of grain starch instead of mushroom compounds.
