No Mycelium. No Fillers. No Imports.
Genuine USA-Cultivated Products
Genuine USA-Cultivated Products
No Fillers. No Fake Extracts. No Imported BS.
Most mushroom powders and “extracts” online are smoke and mirrors—loaded with grain-grown mycelium, starch, and mystery blends from unregulated overseas suppliers. They market themselves as “100% extract” or “pure,” but deliver a weak mix of powdered filler, degraded compounds, and zero transparency.
At Tremetes, we don’t play that game.
We grow real mushrooms—100% fruiting body, cultivated indoors in the USA, with zero grain, zero mycelium, and no imported shortcuts. Just clean, potent, scientifically respected mushrooms that speak for themselves.

Known Origin
Authenticity Matters.
In a market flooded with imposters, most so-called “mushroom extracts” are just imported mystery blends—grown who-knows-where, by who-knows-how, and simply packaged in the U.S. They hide behind vague claims like “100% extract” or “no fillers,” hoping most people won’t question what’s actually inside.
But here’s the truth:
Real Turkey Tail is almost impossible to powder smoothly due to its high chitin content. If it looks like cocoa powder—it’s probably not real. The same goes for Lion’s Mane and Reishi: if it doesn’t say 100% fruiting body, it’s likely bulked with grain or mycelium.
At Tremetes, we don’t cut corners—and we don’t cut the truth.
We cultivate all our mushrooms—Turkey Tail, Lion’s Mane, and Antler Reishi—right here in North America, indoors, from spore to jar. No fake extracts. No mycelium. No starch. No shortcuts.
Each batch is slow-crafted and we test our mushrooms with a globally recognized third-party lab for purity and active compounds. What you get is the real deal:
Clean. Potent. Authentic.
Don’t settle for fakes dressed up in slick packaging.

Beta-glucans
Beta-glucans are biologically active polysaccharides known for their role in supporting immune health—but what many don’t realize is that not all beta-glucans are the same.
Each mushroom species produces structurally distinct beta-glucan molecules, with unique branching patterns that interact differently with the immune system. Turkey Tail, for example, is rich in 1,3/1,6 beta-glucans, closely studied for immune modulation. Lion’s Mane contains neuro-supportive compounds alongside its beta-glucans, while Antler Reishi offers a broad spectrum of adaptogenic triterpenes and immune-active polysaccharides. -
PSK
Polysaccharide-K (PSK), also known as Krestin, is one of the most extensively studied compounds found in Turkey Tail mushrooms. This unique protein-bound beta-glucan has been shown in clinical research to stimulate immune cell activity and support the body’s natural defense mechanisms.
PSK is especially well-known in Japan, where it has been used for decades as a prescription adjunct to cancer therapy, underscoring its credibility in integrative medicine. Its ability to modulate immune responses without overstimulation makes it a standout among mushroom-derived polysaccharides. -
PSP
Polysaccharide-Peptide (PSP) is another immune-active compound found in Turkey Tail mushrooms, structurally similar to PSK but with its own unique profile. Like PSK, PSP has drawn attention for its immune-modulating effects, particularly its ability to enhance the activity of natural killer (NK) cells and T-cells.
Scientific studies suggest that PSP may play a supportive role in integrative cancer care, helping the immune system better recognize and respond to abnormal cells. Its use in traditional and modern research contexts reflects a growing interest in how natural compounds can work in harmony with the body's innate defenses. -
Coriolan
Coriolan is a unique type of beta-glucan found specifically in Turkey Tail mushrooms (Trametes versicolor). Recognized for its immunostimulatory effects, Coriolan has been the subject of ongoing research exploring how it interacts with immune cells to support the body’s natural defense systems.
Its presence highlights the complexity and therapeutic potential of mushroom-derived polysaccharides, reinforcing why whole-fruiting-body Turkey Tail is valued in integrative wellness practices. -
Hericenones
Hericenones are a class of naturally occurring compounds found in the fruiting body of Lion’s Mane (Hericium erinaceus). These unique aromatic compounds have been shown in scientific studies to stimulate nerve growth factor (NGF) synthesis—a protein essential for the growth, maintenance, and survival of neurons.
By supporting NGF production, hericenones are believed to play a role in:
- Neurogenesis (formation of new neurons)
- Cognitive function
- Memory and focus
- Protection against age-related neural decline
-
Triterpenes
Antler Reishi (Ganoderma lucidum) is prized for its high concentration of triterpenes, a group of bioactive compounds responsible for many of Reishi’s most studied effects. These include ganoderic acids, lucidenic acids, and ganolucidic acids—compounds known for their ability to support balance and resilience in the body.
Triterpenes have been shown to:
- Modulate the body’s stress response and promote nervous system regulation
- Exhibit anti-inflammatory and antioxidant activity
- Support liver function and histamine response
- Influence immune signaling and cellular defense pathways (including early-stage tumor research)
The antler form of Reishi, grown under specific environmental stressors (low airflow, high CO₂), naturally produces a denser concentration of triterpenes than the traditional “conk” variety.
