Agaricus blazei Murill: Grown Where It All Began
The Original Source: Brazil
Agaricus blazei Murill (ABM)—also known as the “Sun Mushroom” or Cogumelo do Sol—was first identified in the mid-20th century in Piedade, São Paulo, a region known for its rich volcanic soil and vibrant biodiversity. Locals had long included this mushroom in their traditional diets, and researchers quickly took interest. Today, ABM is one of the most studied functional mushrooms in the world, with over 70 years of published scientific research exploring its naturally occurring compounds that support immune health and overall wellness.*
At Desert Forest Nutritionals, we’re proud to cultivate our ABM mushrooms in the same region, from the same authentic strain, and under the same pristine conditions where this mushroom was originally discovered. This is not a substitute or imitation—it’s the real thing, grown where it belongs.
What makes Desert Forest Mushrooms special?
Not All Mushrooms Are the Same
Mushrooms may look similar, but their quality, potency, and nutritional value depend greatly on where they’re grown, how they’re processed, and which part is used.
Many mushroom products on the market are made from:
- Mycelium grown on grain or rice (which can dilute potency)
- Low-grade imports from regions with limited environmental controls
- Hybrid strains lacking the full nutrient profile of wild-type ABM
In contrast, Desert Forest mushrooms are:
- Made from 100% fruiting bodies (not just mycelium or spores)
- Grown in Brazil, near the Atlantic Rainforest—ABM’s native habitat
- Classified as Ultra Gold Grade for purity, potency, and integrity
The Importance of a Clean Environment
Mushrooms are natural bioaccumulators, meaning they absorb nutrients—and potential toxins—from their environment. That’s why location matters. Our mushrooms are grown in clean air, pure water, and rich soil, far from industrial activity or pollution, in one of the world’s last unspoiled ecosystems.
The result? A clean, nutrient-dense, and authentic extract that reflects the mushroom’s natural power.
Trusted in Japan for Decades
Brazilian ABM mushrooms have long been embraced in Japan and Korea, where they are among the most widely consumed functional mushrooms. Japan imports the majority of Brazil’s ABM harvest—due to its consistency, quality, and full-spectrum profile.
It took nearly 30 years of hybridization and cultivation trials before Japanese growers could adapt the mushroom to local conditions—further proving how uniquely suited ABM is to its original Brazilian soil and climate.
Why the Fruiting Body Matters
Many commercial mushroom extracts use mycelium, which contains fewer active compounds than the fruiting body (the cap and stem of the mushroom). Some products labeled “mushroom” contain mostly grain-based mycelium, with minimal actual mushroom content.
At Desert Forest, we use:
- Whole fruiting body (cap, stem, supporting structures)
- No added starches, maltodextrin, or fillers
- Dual-extraction for both water- and alcohol-soluble compounds
Our extract includes:
- Beta-D-glucans (1-3, 1-6) – studied for their role in immune support*
- Vitamins C, D, beta-carotene, and B-complex
- Essential minerals: zinc, copper, potassium, phosphorus
- Sterols and antioxidants to support overall vitality*
The Problem with Cheap Alternatives
Some products, especially from regions with less environmental oversight, list “mushroom” on the label but contain only mycelium biomass grown on grain. These often:
- Lack meaningful levels of active compounds
- Contain mostly ground grain or rice starch
- Mycelium is not allowed to be marketed as true mushrooms by the FDA (FDA Guidance, p. 22)
These products may appear similar—but they are not the same. With functional mushrooms, you get what you pay for.
