Mushrooms are a delicious addition to many dishes and support your body in remarkable ways.* There are thousands of different types of mushrooms, but in this article, we’d like to focus on one of our favorites: the Chaga mushroom.

We’ll discuss Chaga mushroom benefits and how to work it into your daily routine to take advantage of all it offers.*

Before we hone in on the benefits of Chaga mushrooms, let’s talk about where these fungi grow, what they look like, and their uses over the years.

What Are Chaga Mushrooms?

Chaga mushrooms are scientifically known as Inonotus obliquus, but you might know them as Cinder Conk or Black Mass. Those two names do an excellent job of describing the mushroom’s appearance. This black mass grows on trees and resembles clumps of dark dirt or charcoal

To understand Chaga better, remember that mushrooms are fungi, not plants, and they reproduce via spores. Mycelium, also known as the root system of the mushroom, is created when a spore germinates and then the fruiting body grows, which is the above-ground part that we call a “mushroom” and typically eat.

However, Chaga begins when a fruiting body of a higher fungi species enters a wound of a mature tree, forming a large, hardened mycelial mass (the conk) that will continue to grow, often for many years. 

This mushroom grows in the cold climates of Northern Europe, Northern Canada, Russia, and Siberia and feeds primarily on birch trees. The fruiting body of the Chaga mushrooms is rare to find in nature, and their benefits reside in the mycelial mass.

The History of Chaga Mushroom Use

Russians and northern Europeans grated them into a fine powder and brewed them as an herbal tea for centuries as a folk remedy to support immunity and overall health.*

Modern studies acknowledge this traditional usage. For example, researchers have noted that Siberian folk traditions used Chaga to help with occasional stomach upset, support heart and liver health, help alleviate occasional aches and pains, and support immune health.*REF#1257

Now that we’ve talked a bit about what the Chaga mushroom is and its history, let’s dive into Chaga mushroom benefits and how you can put this wonderful fungus to work in your life.*

What Is the Nutritional Value of Chaga Mushrooms?

Chaga mushrooms are known for their high antioxidant levels and beneficial plant constituents, such as triterpenoids, melanins, polysaccharides, polyphenols, and flavans. However, their exact nutritional composition is unclear. 

While Chaga is available as a supplement, using it to make teas and other infused drinks may not have the same nutritional properties as whole mushrooms. Despite this, Chaga mushrooms are still rich sources of antioxidants.

With low calories, high fiber, and no fat or sugar, two teaspoons of raw Chaga chunks contain approximately 30 calories, zero grams of fat, seven grams of carbohydrates, and seven grams of fiber, making them a potentially beneficial addition to a healthy diet.*REF#1263

6 Health Benefits of Chaga Mushrooms*

Chaga Supports Immune Health*

One of our favorite potential health benefits of Chaga mushroom is that it supports your immune system.* 

Many mushrooms, Chaga included, contain a specific group of polysaccharides called beta-glucans. Polysaccharides are complex carbohydrates composed of many sugar molecules, and beta-glucans support immune function and overall wellness. Chaga studies confirm the mushroom’s ability to help promote a healthy immune system.*

Chaga Provides Antioxidant Support*

Chaga also offers antioxidant support.* This promotes healthy cell growth and turnover and is considered to be a tonic mushroom to supporting overall wellness.*

Antioxidants support your body by stopping or slowing cell damage from free radicals. Neutralization of free radicals minimizes oxidative stress. Polysaccharides are the “main contributors to the antioxidant activity” of mushrooms.*REF#1256

One study found that polysaccharides are the “main contributors to the antioxidant activity” of mushrooms. Its researchers highlighted Chaga’s antioxidant effects specifically.*REF#1256

Ethanol extracts from the Chaga mushroom showed the highest antioxidant activity among the five mushrooms they tested, making this mushroom “a novel antioxidant candidate.*REF#1256 Antioxidants are also commonly used in skincare to promote younger appearances and even complexions.

Along with the high antioxidative properties of Elderberry and Astragalus, you can get antioxidant support from Chaga mushroom with Immune Shine™ by adding this delicious powder to any beverage. 

Chaga Supports Gastrointestinal Health*

The non-digestible polysaccharides in Chaga mushrooms also function as a prebiotic, nourishing the good bacteria in your gut to flourish.* A healthy gut microbiota is essential for good gastrointestinal, immune, and overall health.

One study showed that the polysaccharides in Chaga mushrooms “induce changes in the gut microbiota and…bring the changes towards a healthy bacterial profile.”*REF#1258

Chaga Can Support Healthy Cholesterol Levels

Chaga mushrooms are known for their potential to support healthy cholesterol levels.* This effect is due to compounds called triterpenes. These triterpenes, such as lanosterol and inotodiol, can inhibit an enzyme called HMG-CoA reductase, which plays a vital role in cholesterol synthesis in the liver.REF#1259

Through that process, Chaga mushrooms may help address the cholesterol synthesized in the liver.* In addition, Chaga mushrooms also support the production of bile acids, which can help to eliminate excess cholesterol from the body.REF#1259

Several animal studies have supported these effects of Chaga mushrooms. For example, one study found that mice fed a high-fat diet and supplemented with Chaga mushroom extract had healthier levels of total cholesterol and LDL cholesterol than mice that did not receive the extract.REF#1259

However, more human studies are needed to confirm these benefits of Chaga mushrooms. It's also important to note that Chaga mushrooms are not a substitute for medication. Consult your healthcare provider before starting any herbal remedies.

Chaga May Support Long-Term Wellness

Chaga mushrooms may support long-term health because they are rich in antioxidants, molecules that can neutralize free radicals and protect cells from damage. This process may help support long-term health by protecting DNA against changes that can lead to long-term complications.REF#1260

Chaga mushrooms may also help support the immune system, which can help the body defend itself against long-term health concerns.REF#1261

Chronic physical stress may be a precursor to long-term health complications. Chaga mushrooms may help soothe this bodily irritation, therefore supporting long-term wellness.REF#1262

Chaga May Support Healthy Blood Sugar Levels

Chaga extract may help support blood sugar levels and glucose tolerance, as well as promote a healthy amount of glycogen in the liver.REF#1264

The mushrooms may also help protect organs and support the levels of antioxidants in the liver. Research suggests that I. obliquus polysaccharides might be a promising herb to promote balanced blood sugar levels.*REF#1264

How to Use Chaga Mushrooms

Chaga Mushroom Side Effects and Precautions

Remember that before taking any new herbal supplement, Chaga mushroom supplements included, you should consult your doctor or naturopathic physician, especially if you are already taking any medications or have an existing medical condition.

The Food and Drug Administration (FDA) does not regulate these supplements, so obtaining medical advice before use is essential.

Those with heart disease or who are taking medication for blood pressure should exercise caution when using Chaga or other medicinal mushrooms, as they could potentially interfere with medication.*

Avoid taking Chaga mushroom if you have an autoimmune disorder, as some compounds may stimulate immune function.*

Gaia Herbs Everyday Immune Mushrooms & Herbs, Immune Mushroom Blend, and Immune Shine™, which all contain Chaga mushrooms, should also not be used during pregnancy or lactation.*

Other Beneficial Mushrooms

Along with Chaga, there are many other types of mushrooms that provide different health benefits, which is why we pair them with our supplements. 


Cordyceps (Cordyceps militaris) grow in the Himalayan foothills and infect ghost

moth caterpillars, from which their fruiting body grows. However, they can also be cultivated on a barley substrate, making them vegan.

Highly valued in Traditional Chinese Medicine, Cordyceps are adaptogens that can support the immune system, kidneys, and lungs and promote healthy stamina and physical energy levels.* Support these functions and your stress response with Cordyceps Mushroom Energy Support
