The Longevity Mushroom
Reishi has long been considered a potent immune modulation mushroom. It contains beta-glucans as well as uniquely bitter triterpenes like ganoderic acids.
All organically grown and extracted to increase the bioavailability of the beneficial compounds.
Why Beta-Glucans Matter
Beta-glucans are the most abundant and primary active compound found in mushrooms and mycelium.
These complex polysaccharides are where much of the immunological benefits come from which is why it is so important to validate and guarantee beta-glucan content.
A lack of beta-glucans can be attributed to many things like low quality ingredients, improper processing and extraction or the addition of fillers like grains (see alpha-glucans).
All Real Mushrooms products have verified levels of beta-glucans right on the label so you can trust that you're getting the benefits you deserve.

Why we are rated #1 for quality.
Purity. Potency. History.
From a frustration with a lack of quality and transparency in functional mushroom supplements, Real Mushrooms was born.

Backed by over 40 years of experience, we continue to pioneer functional mushroom supplements supported by scientific research.
Beta-glucans Guaranteed
The beneficial mushroom compounds you want are right on the label.
Zero Grain Fillers
Unlike myceliated grain alternatives, our mushroom extracts contain absolutely NO grains or starch fillers.
Do You Really Know What’s in Your Mushrooms?
Many products that claim to contain mushrooms actually contain none. What they are is the mushroom's root system, known as mycelium, which is grown on grains like rice and oats and this grain cannot be separated from the final product. This residual grain contributes high levels of starch which in turn dilutes the potential for active compounds like beta-glucans.
A 2017 study from Nature on reishi supplements found that 74% of products were inauthentic with 68% containing starch-like polysaccharides (ie. fillers).
ConsumerLab also found similar results in their reishi report and found Real Mushrooms to be their #1 choice.

Frequently Asked Questions
Where are your mushrooms from?
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 medicinal 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 American since it is too expensive. In fact, 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.
Is it true that Reishi is bitter in taste?
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 for reishi. Reishi products that aren’t bitter can be assumed to have negligible amounts of triterpenes.
If you are not a fan of bitter tastes, we do recommend going with our capsule version instead.
Why do you dual extract your Reishi mushrooms?
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 extract powder that provides maximum potency and health benefits.
Why do you use mushrooms and not mycelium?
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 have a very large body of research. 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 separate 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 their products with verified levels of the important active compounds like beta-glucans and always guarded against starchy fillers like grain.
How can Reishi benefit me?
Using modern research techniques, scientists have determined that reishi mushroom benefits for supporting longevity and wellness are indeed abundant. 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.
Why do you only list beta-glucans and not polysaccharides?
Beta-glucans, which are a polysaccharide, are the most well researched medically active compound in mushrooms. 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 it can be easily doctored using starch-like substances like grains.
