Real Ingredients
The Longevity & Mood Mushroom
Known as the “King of Mushrooms,” Reishi has been used for centuries to support vitality, resilience, and healthy aging. Its naturally occurring compounds, beta-glucans and triterpenes like ganoderic acids, have been studied for their role in immune, cardiovascular, and metabolic health.†
Reishi is also valued for its adaptogenic qualities, helping the body respond to stress and promoting a sense of calm. Our Reishi mushroom supplements offer a natural way to enhance your wellness routine and support graceful aging from the inside out.
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 Reishi contains only the real mushroom, grown, extracted, and tested with integrity.

★★★★★
“I have been taking reishi regularly for almost 4 years. My favorite way to take it was at work, as a mid to late day pick me up/"god-help-me-I'm-so-ready-to-go-home" remedy. Mix with cacao powder, hot water and coconut butter, it was instant gratification in a cup, inner calm mixed with a subtle boost.”†

Why Beta-Glucans Matter
Beta-glucans are the primary active compounds in Reishi 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.

Cindy M. I use combo Lion’s Main and Reshi in my morning coffee daily. When I recently moved and ran out of product I was reminded why I take these products! I got a viral cold for the first time in years and had a horrible time sleeping. Got it all restarted and all is better again!

Michele D.H. Many, many years ago, after much investigations, I was stunned of all the high-quality levels of these mushrooms. Then I learned that the turkey tail and the reishi strengthen the whole immune system for cancer patients too. Mine is rare. Now I will happily continue taking those along with the lion's mane for strengthening by well being throughout the future.

Diana R. I love Real Mushrooms. They have a wide variety of mushrooms to choose from. I buy the extract powders, they dissolve completely in my coffee and I like the taste they add to it. It’s been tough to find mushrooms that don’t have grains and mycelium, plus taste good. Definitely a company I trust and will continue to purchase from.

Jonathan Excited to start using.

Meleji This is the best Reishi product on the market. I’ve done my research. Their hot water extraction yields the second highest beta-D glucans and highest triterpines. I’ve tried FreshCap and Host Defenses stuff, and it’s great, but if you want the very best going into your body, this is it. Get the big bag and youre set for 100 days.

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.
Yes, this is because of the triterpenes found within the Reishi mushroom. Triterpenes give Reishi its bitter flavor, and this bitterness is a good quality indicator of Reishi. Reishi products that aren’t bitter can be assumed to have negligible amounts of triterpenes.
If you do not like bitter tastes, we recommend going with our capsule version instead.
Since Reishi contains beneficial compounds that are both water-soluble and insoluble, Real Mushrooms uses double (a.k.a. dual) extraction to create our potent Reishi mushroom extract.
The mushrooms are run through both processes, and the resulting liquids are combined and evaporated to make one final Reishi extract powder that provides maximum potency and health benefits.
Reishi mushrooms contain bioactive compounds that have been studied for their potential role in overall wellness and vitality†. This fungus contains over 400 different bioactive compounds, including triterpenoids, polysaccharides, nucleotides, sterols, steroids, fatty acids, proteins, peptides, and trace elements.
They contain hundreds of bioactive compounds, mainly in the form of polysaccharides and triterpenes, that assist the body in numerous ways.
Some of the research-backed benefits of Reishi include:*
- Supports immune health and resilience
- Supports mood and emotional well-being
- Promotes restful sleep and relaxation
- Supports energy, vitality, and healthy aging
- Helps maintain general wellness and resilience to stress
- Promotes cardiovascular and circulatory health
- Helps maintain healthy blood sugar metabolism
- Supports liver health
- Provides antioxidant support
- Promotes healthy inflammatory response
Beta-glucans are naturally occurring polysaccharides found in mushrooms and are among the most studied compounds for their functional properties*. For this reason, we specifically measure beta-glucan levels on our products.
We do not believe in using polysaccharides as a measure of quality as they can be easily doctored using starch-like substances like grains.
Whether you’re training hard or just looking for more natural energy throughout your day, Cordyceps may help you feel more resilient, active, and ready to perform.
