Mushrooms play an essential role in the ecosystem, breaking down organic matter and helping recycle nutrients for other plants. Across cultures, they have been valued for their culinary and nutritional benefits—and in some traditions, for traditionally valued for supporting overall wellness. Scientists have identified over 1.5 million species of mushrooms, though only a fraction are edible or considered beneficial.
No, there are millions of different types of mushrooms, some are poisonous others are edible. A very small percentage are actually medicinal.
Research shows that compared to other medicinal mushrooms, ABM contains the highest concentration of Beta-D-Glucan and are rich in Ergosterol, Linoleic Acid, Palmitorenic Acid and Vitamins D, B6 and B12. They are the strongest of all medicinal mushrooms.
Yes. Some pharmaceuticals are derived from mushrooms, but ABM is a dietary supplement, not a drug.Several pharmaceutical compounds, including antibiotics and immune-modulating agents, have been developed using isolated compounds originally found in mushrooms. These drugs are synthesized, studied, and regulated as medications—unlike dietary supplements.
Agaricus blazei Murill is a functional mushroom native to Brazil, valued for its whole fruiting body. Unlike grain-based mycelium products, ABM is cultivated, harvested, and extracted to preserve natural compounds reputed to support immune balance, enzyme activity, and overall vitality.
No—while all are medicinal mushrooms, ABM stands apart with its unique profile: naturally high in beta‑glucans, vitamin D precursors, B‑vitamins, and antioxidants. That makes it distinct in how it supports immune and metabolic wellness.
Many people choose to take the extract on an empty stomach, mixed with a glass of water and powdered vitamin C, to may help absorption. Always follow label instructions and adjust to your personal routine.
Some studies suggest vitamin C may enhance absorption of certain compounds.
1000 mg of powdered vitamin C or buffered Ester C would be best. We do not recommend capsules as they too dissolve slowly.
You can take it straight, mix it in water or tea, or blend it into smoothies. We personalize daily intake amounts to support your goals, health status, and routine—because one-size doesn’t fit all.
There’s no single “best” time. Many take it in the morning or early afternoon for daily support, while others use it around workouts or with meals. We’ll help you find the timing that fits your lifestyle during our Discovery Call.
If you have a known allergy to mushrooms, you should not use this product. If you are pregnant, nursing, or taking medication, consult your healthcare provider before use.
No, Toxicity studies have shown that the mushrooms have very low toxicity. They are considered and classified as GRAS or Generally Recognized as Safe
Most people tolerate ABM well. However, anyone with mushroom allergies or medical concerns should consult their healthcare provider before use.
Generally well-tolerated, but individual reactions may vary.
ABM mushrooms contain naturally occurring minerals, amino acids, B-vitamins, enzymes, polysaccharides (including beta-glucans), antioxidants, dietary fiber, sterols, and compounds such as saponins and SOD (superoxide dismutase). These nutrients work together to support overall wellness.
SOD’s are one of the most important anti oxidants in our body. They decrease as we age. They are frequently used in skin creams, for burns, wounds and as an anti inflammatory.
Our ABM extracts consistently measure greater than 20% beta-glucans. Because ABM is a whole food, levels vary naturally from batch to batch and depend on growing conditions. To ensure quality and consistency, every lot is tested for beta-glucan content using the Megazyme Yeast & Mushroom β-Glucan Assay.
Price. Mushrooms from Brazil are usually of a higher grade and quality and thus more expensive while ABM from other markets, especially Southeast Asia, are usually very inexpensive. This is also true with lower grade mushrooms grown in Brazil. Japan, which in the past purchased mushrooms from Southeast Asia, is currently purchasing about 90% of the mushrooms cultivated in Brazil because of its international reputation for quality and safety. This has prompted the Southeast Asian producers to seek alternate markets. Presently the U.S., Canada and Europe are experiencing an influx of AbM mushrooms grown in southeast Asia. The true AbM mushroom product should state “Product of Brazil” on the label. Our mushrooms ARE 100% authentic Brazilian.
The Japanese market are still the largest consumer of ABM mushrooms, importing 90% of the ABM grown in Brazil. Why is that? Brazilian ABM have a reputation for being of the best quality in the world. The bottom line is that you can copy technology but you can’t copy the natural resources, especially the soil and climatic conditions. Also, the Brazilian AbM have shown to have higher levels of polysaccharides, which make them more effective.
Brazilian-grown ABM benefits from the nutrient-rich soils of the Atlantic Rainforest and traditional cultivation methods that allow the mushrooms to fully mature. This results in a fuller, more potent fruiting body, distinct from rushed or filler-heavy commercial formulas grown elsewhere.
Because of these conditions, Brazilian ABM consistently achieves Gold or Ultra Gold quality. Combined with careful processing, it produces extracts with greater than 20% beta-glucans, verified through laboratory testing for potency and consistency.
Always whole fruiting body. Mycelium grown on grain is less potent and often includes starch fillers. We only use true mushrooms harvested at peak maturity.
How long does it take to notice changes? Results vary by individual and usage.
ABM is known for:
We use the Megazyme Yeast & Mushroom β-Glucan Assay, a specialized laboratory test designed specifically for mushrooms and fungi.
Why this matters:
When we say our ABM extracts consistently average greater than 20% beta-glucans, it’s not a marketing guess — it’s the result of a lab-verified, industry-standard test.
ABM mushrooms contain naturally occurring polysaccharides, such as beta-glucans, which are known to support a balanced immune response. Rather than overstimulating or suppressing, these compounds may help maintain a balanced immune response or maintain homeostasis—its natural state of internal balance. A healthy immune system is key to helping the body respond appropriately to daily challenges.
Various factors can affect your immune system but the most common are poor diet, lack of sleep, stress, and toxic chemicals. Individuals with a weakened immune system are more susceptible to diseases, viruses and infections of all types.
To be healthy you need a balanced immune system. Common conditions associated with immune dysfunction are: cancer, chronic Fatigue Syndrome, Hepatitis B & C, high cholesterol, autoimmune conditions like Rheumatoid Arthritis, Fibromyalgia, Lupus, Crohn’s Disease and Hashimoto Thyroiditis.
There are basically three grades of ABM mushrooms available: Silver, Gold, and Ultra Gold. The lower the grade, the lower the concentration of polysaccharides they contain. The higher the grade, the richer they are in active compounds and the more effective they will be.
Climatic conditions play a critical role in determining the final quality. ABM only grows under very specific conditions, which is why early attempts to achieve constant yields in laboratories were largely unsuccessful until the 1990s. Brazilian-grown mushrooms, cultivated in the nutrient-rich soils of the Atlantic Rainforest, are usually graded Gold or Ultra Gold, while mushrooms grown outside Brazil (China, Japan, or the U.S.) are more often graded Silver.
At Desert Forest Nutritionals®, we go beyond traditional grading:
Our Brazilian ABM extracts consistently measure greater than 20% beta-glucans, verified through the Megazyme Yeast & Mushroom β-Glucan Assay. This ensures that when we say “Gold” or “Ultra Gold,” it reflects scientifically verified potency, not just a label.
Functional foods are nutrient rich foods that can have a potentially positive effect on overall health. Mushrooms fall into this group.
Our ABM is grown in pristine regions of Brazil, on dedicated farms with rich, biodiverse soil. We oversee every step—Harvesting at full maturity, drying, and extracting in ways that best preserve nutrients.
Yes. We work with farms that practice responsible cultivation and maintain healthy soil ecosystems. And we avoid waste: every part of the fruiting body is used in our extracts.
No. The FDA does not approve dietary supplements. However, our facility follows FDA guidelines for food safety, and our product is manufactured under strict quality standards. Desert Forest Nutritionals® is also registered with the FDA as required for food importers.
ANVISA (National Health Surveillance Agency) was established by the Brazilian Ministry of Health in 1998 to regulate and enforce Good Manufacturing Practices according to the World Health Organization and Mercosul guidelines. ANVISA regulates the installation of equipment, technologies, environment and the manufacturing procedures for medical devices and equipment, pharmaceuticals, food and supplements, cosmetics and tobacco. Products must be registered with ANVISA prior to sale in Brazil. ANVISA also supervises and inspects the above-mentioned products prior to exportation to other countries. ANVISA requires that all products from foreign countries have a representative in Brazil, similar to the regulations established in 2002 by the FDA in the U.S. For more information on ANVISA please visit: http://www.anvisa.gov.br/eng/index.htm
We offer only one extract—Ultra Gold—because it represents the highest standard of quality and effectiveness. It’s made from Brazilian-grown Agaricus blazei Murill, using the whole fruiting body, and extracted with a dual process (hot water + alcohol) to deliver the most complete spectrum of naturally occurring compounds.
Ultra Gold contains naturally higher levels of beta-glucans, antioxidants, triterpenes, and sterols compared to lower-grade extracts. It’s trusted by wellness practitioners in Japan and crafted for those who want complete, full-spectrum support—not diluted or commercialized versions.
Yes. Ultra Gold is available as a liquid extract (in multiple sizes) and as a pure powder. We’ll help you choose the best format and serving amount based on your wellness goals.
Yes, We test EVERY single lot. Third party internationally recognized laboratories test our products. A permanent technical team specializing in edible mushroom cultivation supervises the entire cultivation process from the production of the mycelium to the final packaged product. The entire cultivation process is also inspected by ANVISA (Brazilian Health Survelliance Agency) as well as inspected again before being exported from Brazil. The FDA upon arrival also inspects our products. Our company is registered with the FDA and is in compliance with the new regulations for Food Importation Bioterrorism Act of 2002.
No, our product is a whole food product, which means it maintains all of its original nutritional composition. When you standardize a product you extract only one ingredient or constituent but you lose all of its nutritional value in the process. The ABM mushroom has 192 nutrients, including anti-oxidants, amino acids, minerals, vitamins, enzymes, dietary fibers, Heteroglucans, SOD, Triterpenes, natural sterols and Saponins. AbM mushrooms contain the highest levels of beta-D-glucan and Ergosterol. Studies show that both of these nutrients together make ABM so effective.
We use whole fruiting body mushrooms, avoid fillers, and extract using tested methods. Each batch undergoes third-party lab testing for purity, potency (beta‑glucans), and safety (no heavy metals or contaminants).
Yes. We provide lab certificates on request and often embed badges like “Brazilian-grown,” “Whole Fruiting Body,” and “Lab Tested” to show our commitment to transparency and quality.
No. We do not use maltodextrin or synthetic carriers in our powder extract. Instead, we use a small amount of organic manioc (cassava) starch—a clean, food-grade, plant-based carrier—only when necessary during the spray-drying process to maintain extract stability.
This natural method helps preserve the quality of the bioactive compounds without compromising purity, while avoiding the common use of GMO-derived maltodextrin found in many other products. Our goal is always to deliver a highly concentrated, easy-to-use powder with minimal, natural processing support.
No. Our products are 100% non-GMO. The Agaricus blazei Murill mushrooms we use are naturally grown in Brazil using traditional, non-genetically modified cultivation methods. We do not use any genetically engineered ingredients at any stage—from growing to extraction.
Our mushrooms are non-GMO by nature, but we do not carry a third-party Non-GMO certification. You are getting a pure, natural mushroom extract—just as nature intended.
Our ABM mushrooms are organically cultivated in Brazil using traditional methods—without synthetic pesticides, herbicides, or chemical fertilizers. They’re grown in nutrient-rich soil, under carefully monitored environmental conditions.
Once harvested, only the best mushrooms—fully matured, intact, and visually inspected—are hand-selected for extraction. We never use immature mushrooms, broken fragments, or mass-harvested material.
Yes. Every batch of our Ultra Gold extract undergoes rigorous third-party testing to ensure purity, safety, and consistency. We test for:
Beta-glucan content is verified using the Megazyme Yeast & Mushroom β-Glucan Assay, the industry-standard method for accurately measuring fungal beta-glucans.
We also confirm that each batch meets quality specifications for moisture, appearance, and shelf stability. Our goal is to deliver a mushroom extract that is not only effective—but clean, reliable, and consistent every time.
