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.”

Real Quality

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™ Verified Mushroom Identity Certification—a cutting-edge genomic testing standard that confirms we use the correct mushroom species and nothing else.

I put it in my coffee rvery morning
I dont notice any difference using it or not. I just know its good for me

I buy the powders as they are just exactly what they are. Mushrooms. No grains, no fillers. There are no caps that have sneaky ingredients either. I used to take just the 5 defenders, but as of recently. I take the Reishi, Lions Mane, Cordyseps, and Turkey Tail in my morning protein shake. I was adding a small amount of cacao in with it. But I have stopped bc it gives me terrible indigestion. I will continue to use my mushrooms for now. It has become very pricey doing it this way, and i may have to cut back or just order when they have sales. I regret it bc that means i won't get to use them daily. Yet. Money gets to be funny. Either way, it's a great and amazing product. Both my pet and i have taken this. I highly recommend the powders.

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.
