The Non Mushroom

While commonly called a mushroom, Chaga is a unique fungal canker that primarily grows on birch trees. This dense woody mass contains beta-glucans, melanin, initidiol and birch compounds like betulin and betulinic acid that can help to support your immune system†.

All wild harvested from Siberia and extracted to increase the bioavailability of the beneficial compounds like beta-glucans.

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.

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.

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.

What is the difference between capsules and powder?

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 purposes, where as the powder can be great added to recipes or mixed in coffee, tea or bone broth.

What is the recommended dosage for my pet?

1 capsule for each 20-40 pounds of body weight daily, or as recommended by your veterinarian.

If your pet is under 20 pounds, you may still give them 1 capsule daily.

Does your Chaga extract contain Xylitol?

Chaga is a fungus that grows on Birch trees and relatives of the birch tree. When the fungus grows into the tree bark it absorbs molecules, including the tree sugar, xylan, into its cankerous growth on the tree. When that exuberant growth is harvested to be used, these molecules of xylan will be included in the chaga canker. Xylitol, which is highly toxic to dogs and cats, is an alcohol sugar derived from xylan. It is not naturally occuring in the birch tree or Chaga canker, and needs to be chemically converted in a laboratory to make xylitol. There is no xylitol in our chaga extract.

We sent our Chaga extract to a 3rd party laboratory for analysis of xylitol, and the results came back as we had suspected; zero xylitol was found in the sample we sent.

How can Chaga benefit my pet?

Chaga may be helpful for certain skin conditions, may support digestion, and may also offer blood sugar support.
