Think of 5 Defenders® as your mushroom “multivitamin.”
Whether you're looking for daily wellness support or to maintain long-term health, this pure, organic blend of five functional mushrooms offers a natural, safe, and effective solution.
We have crafted a synergistic, immune-supporting mushroom complex, using decades of research and traditional use to craft this formula. 5 Defenders® mushrooms are known for their high levels of beta-glucans, compounds studied for their ability to help maintain a healthy immune system.*
5 Defenders® creates a broad-spectrum foundation for wellness, supporting not just the immune system, but the conditions that allow it to function optimally.
- Reishi promotes calm and supports a healthy stress response
- Shiitake and Maitake offer immune-modulating compounds and support metabolic function.
- Turkey Tail delivers powerful polysaccharides like PSK and PSP, which may support the activation of important immune pathways.
- Chaga brings potent antioxidant activity to support cellular health.
Take 1/2 teaspoons (approx. 1 gram) of 5 Defenders® extract powder with or without food, or as recommended by your healthcare professional.
Many customers find it easiest to incorporate 5 Defenders® into their morning wellness routine by blending the powder into their coffee, tea, or smoothies.

Real Ingredients
Balanced Immune Response†
This mushroom complex is a blend of five extract powders: Reishi, Shiitake, Maitake, Turkey Tail mushrooms and Chaga. They are renowned for their naturally high levels of beta-glucans, polysaccharides that can help balance your body's natural immune response.† Our extract is optimized to contain more than 20% beta-glucans, ensuring consistent, effective support in every serving.
Real Mushrooms, Not Filler
Most mushroom supplements fail because they’re made without mushrooms: they use mycelium fermented grain. Those products have few beneficial fungal compounds—they’re mostly starch.
We use 100% hot water-extracted mushrooms (fruiting body) to unlock the true full spectrum of beneficial compounds.
Highest-Quality, Organic Ingredients
We partner with experienced mushroom growers using Di Dao 地道 (spiritual homeland) cultivation practices to harvest mushrooms in their geo-authentic environments. Our 5 Defenders® contain only the real mushroom, grown, extracted, and tested with integrity.

Real Quality
Why Beta-Glucans Matter
Beta-glucans are the primary active compounds in 5-Defenders mushrooms that support immune function.* Most mushroom products don’t list beta-glucan content, but we do.
Beta-Glucans indicate an authentic mushroom product versus myceliated grain products that contain high levels of starch (Alpha-Glucans) instead.
Real Mushrooms offer potency you can trust, in every capsule.
We use only 100% mushroom (fruiting body)—no grain, no mycelium, no fillers.
This product has received the Purity-IQ™ Authenticity Certification Program - a cutting-edge nuclear magnetic resonance technique that confirms we use the correct mushroom species and nothing else.

Faithia K. Just to start I want to thank Real Mushroom for the great customer support that they have working for them.
Since I was introduced to this company I read upon the products that they offer. For years I have was buying coffee with lions mane and found it wasn’t doing much for me so I decided to buy direct from Real Mushroom. Lions Mane and the Defender. Results are fantastic. Lions Mane is what I take in the morning and Defender at night. Focus andr relaxed is how these products make me feel. Remembering for my cognitive as I am getting older is most important for my aging wellbeing. With that I find Lions Mane is really working and my go to. Thanks again for you support and I definitely will be spreading the word 🙏

Jessica S. My husband and I have been using 5 Defenders for about a year now. It has kept our immune systems stronger and more resilient. Digestion is improved. Our general mood and ability to manage stress is so much better. I've also noticed it helps keep migraines at bay and has stopped them even. It helps with restless leg and perimenopausal symptoms.
Thank you. So much, Real Mushrooms. 🙏

Frequently Asked Questions
All our mushroom extracts are from the leading supplier of organic mushroom extracts: Nammex. They have over 40 years of mushroom growing experience and were one of the first companies to bring organic functional mushroom extracts to North America.
Their ingredients go through rigorous quality control and are tested twice for heavy metals, agricultural chemicals and microbial contamination to ensure they meet all standards for dietary supplements of this nature. All of their extracts are made from certified organic mushrooms (fruiting bodies), organically grown or wildcrafted from deep within mountain regions of China.
Mushrooms used for dietary supplements are seldom grown in North America since they are too expensive. China is the leading supplier of mushrooms worldwide and supplies over 90% of the world’s mushrooms.
It has a rich history of mushroom use as both food and medicine and is the birthplace of mushroom cultivation, with shiitake being farmed in the early 1200s. China is one of the only places in the world where you can get 100% organic mushroom (fruiting body) extracts that can be sold at an affordable price.
The products are identical. The only difference is how you want to consume them.
2 capsules is equivalent to roughly a 1/2 tsp of the mushroom powders.
In terms of potency and efficacy, both the capsules and powders are equally effective at delivering.
The capsules are great for travel, whereas the powder can be added to recipes or mixed in coffee, tea or bone broth.
It is extremely important to distinguish the difference between mushrooms and mycelium.
Mushrooms are the "fruit" and reproductive stage of these organisms, while the mycelium is the root system or "body" of the fungus.
Mushrooms contain much higher levels of active compounds like beta-glucans, and there is a large body of research on them. They have also been consumed for thousands of years as food, and many health benefits have been shown from just mushroom consumption.
Mycelium is commonly grown on a grain substrate, and this grain cannot be separated from the mycelium, so much of the final product is actually grain with no mushrooms present. This shows up in high amounts of starch and low amounts of active compounds like beta-glucans.
For these reasons, Real Mushrooms® only utilizes mushrooms in all of its products, with verified levels of important active compounds like beta-glucans, and is always guarded against starchy fillers like grain.
5 Defenders® is a blend of organic mushroom extracts designed to help support overall well-being, resilience, and immune system health.
5 Defenders® is where most customers begin with Real Mushrooms®.
While single-mushroom supplements can be helpful for targeted needs, they often address just one slice of the wellness picture. Real Mushrooms®' 5 Denfenders® blend, however, supports:
- Innate and adaptive immune function
- Oxidative stress resilience
- Calm, balanced energy
- Gut and microbiome health (through Turkey Tail's prebiotic-like effects)
The blend is derived from 100% organic mushrooms, not myceliated grain, so you get potency without compromise: no starch, no fillers, just the active compounds your body can actually use.
5 Defenders® is a blend of extract powders consisting of:
- 30% Turkey Tail Mushroom
- 20% Reishi Mushroom
- 20% Shiitake Mushroom
- 20% Maitake Mushroom
- 10% Chaga
