Reishi Mushroom Extracts FAQs

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.

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.

Choose our Reishi mushroom supplements to incorporate traditionally valued functional mushrooms into your daily routine. Our extracts are carefully produced to ensure they are rich in beneficial compounds, offering a reliable, effective solution for those looking to integrate these health benefits into their daily routine.

Our organic Reishi capsules and extract powders are made with zero fillers, starch, or mycelium fermented grain. They are extracted and third-party tested for the highest potency and purity. These measures ensure you get a high-quality mushroom supplement with a full spectrum of easy-to-digest nutrients & active compounds.

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.
