The Best Cordyceps Supplement – Our Top 3 Picks for 2023

Last Updated on April 7, 2023

Are you looking to buy top quality Cordyceps mushrooms products in the United States? This guide will help you find the best source for this medicinal mushroom and ensure you’re getting the highest quality product.

Cordyceps have quickly become some of the most popular medicinal mushrooms in the North American market. While countless studies have shown them to have health benefits for athletic performance, libido and cardiovascular function, not all Cordyceps products on the market may be equally effective. In fact, the potency and effectiveness of medicinal mushroom supplements have been shown to highly vary depending on the producer. Many supplement companies have in fact been accused of selling fraudulent supplements that only contain small portions of fungally derived components. 

Thankfully, finding a quality Cordyceps supplement doesn’t require you to have any sophisticated knowledge or technology. All you need to know is how to properly read the product labels to identify the quality of the supplement.

What are Cordyceps Mushrooms?

Cordyceps are medicinal mushrooms with potent biochemical properties and a fascinating ecology. They have been used traditionally for centuries, with high esteem for improving well-being and longevity. They also considered energizing, able to improve athletic performance, respiration, and libido from just a single dose. 

The ecology of cordyceps is particularly intriguing and unique. They parasitize insects, feeding on their live tissues, and even altering their behaviors! While there are hundreds of cordyceps species that occur in the wild there are two main types of Cordyceps that are conventionally used in medicine. These are Ophiocordyceps sinensis aka “Chinese Caterpillar Fungus” and Cordyceps militaris aka “Scarlet Caterpillar Club”. 

Health benefits of Cordyceps

The Cordyceps mushroom has been scientifically proven to: 

Other Potential Health Benefits

Our Selection Process for High Quality Cordyceps

1. Mushroom fruiting bodies

While most Cordyceps supplements are traditionally made with the fruiting bodies or mushrooms of the fungus, some are made with fungal mycelium. Fungal mycelium is the white filamentous “body” of the fungus that is often seen growing within logs or leaf litter in nature. It is from this mycelium that the mushrooms we are familiar with grow. 

While fungal mycelium has been shown to contain many of the bioactive compounds found in fruiting bodies, mycelium-based products are generally considered inferior. This is because mycelium products are not composed of pure mycelium but often contain other fillers like grain. The mycelium used in the supplement industry often originates from grains that have been colonized by the fungal mycelium. While there is a high turnover of the plant-based substrates into fungal tissues, there is still an overwhelming amount of grain that is left over. This means they not only contain a low percentage of fungal biomass but also unwanted components like starches found in the grains. 

Certain Cordyceps supplements may actually be produced with 100% mycelium. This is the case for some “Ophiocordyceps” products that are made with a high-potency mycelium called CS-4. Pure mycelium products are considered to be much more effective than those which contain grain. 

How Do I Know If My Mushroom Supplement Contains Grain? 

  • Read the label and check the ingredients. In most cases, they will mention it directly if it contains grains like brown rice, wheat, millet, or oats. 
  • Companies using pure fruiting bodies will often mention this directly in the label as well. If this is not mentioned it may indicate that they are not using pure mushroom fruiting bodies.

2. Cordyceps Sinensis CS-4 vs Cordyceps Militaris

It is important to note that Cordyceps products can originate from two distinct species. Ophiocordyceps sinensis is the original mushroom that grows from caterpillars in the mountains of China. It has been used in Traditional Chinese Medicine for centuries, however due to its rarity and expensive price due to demand, it is not commercially used in medicinal mushroom products. Instead, a variation of it is created called CS-4 Cordyceps, using liquid mycelium.

Cordyceps Militaris is the second species of mushrooms used in medicinal mushroom products. The most common products in the market today originate from Cordyceps militaris while the more traditional and expensive products come from Ophiocordyceps sinensis (not to be confused with liquid mycelium version CS-4)

While both of these have distinct medicinal properties, Cordyceps militaris is generally thought to be superior for several reasons. These include the presence of unique compounds like cordycepin, the fact that it is created from the fruiting body, and that they are considered much more sustainable alternatives. There is 90x more Cordycepin in militaris compared to sinensis.


3. Ideal extraction method 

Extractions are important for concentrating the medicinal components of Cordyceps and making them bioavailable. Because of this proper extraction methods are necessary to ensure the potency and effectiveness of the product. 

Dual Extractions may not be necessary for Cordyceps products

Many medicinal mushroom supplements are produced using the Dual Extraction method. It is considered “dual” because they use both water and alcohol as solvents. This ensures the extraction of both water-soluble and non-water-soluble components. The most important compounds found within Cordyceps are easily extracted with water but some are still proponents of the dual extraction. 

Water extraction is typically done by decocting pulverized mushrooms in hot water for several hours. This is useful in extracting the active components such as Adenosine, Cordycepin, Cordycepic Acid, and Beta-glucans. 

○ Adenosine and Cordycepin are the most bioactive compounds found within Cordyceps. Cordycepin is exclusive to Cordyceps militaris and not found within Ophiocordyceps sinensis. 

○ Cordycepic Acid is also known as D-Mannitol and has various activities including anti-cancer properties. 

○ Beta-glucans are fungal polysaccharides shown to have great benefits to immune function. 

Alcohol extraction is not considered to be particularly beneficial for Cordyceps although some proponents suggest it likely helps incorporate more obscure compounds. An alcohol percentage of 20% is also beneficial for the shelf life of tinctures. High quantities of alcohol are not recommended for Cordyceps tinctures as they may dilute the water-soluble medicinal component.

4. Extract powders and capsules 

Extract powders are typically produced by evaporating the solvents used in the extraction process. In some cases the original fungal biomass used during the extraction may be incorporated back into the evaporated extract, this produces a 1:1 Powdered Extract. Powdered extracts are what is typically placed within capsule and other supplement products like supplement formulas, food, and beverages. 

Mushroom powders are the items that require the most caution as to avoid grains. Since many regulatory agencies do not require supplement companies to specify between mushroom, mycelium, and myceliated grain they often use ambiguous ingredients in the product packaging. They may say mushroom powder, cordyceps powder, and other non-specific ingredients. Most companies actually using fruiting bodies will proudly list “100% Cordyceps Fruiting Bodies” or something similar on their label. 

5. Beta glucan content on the label 

The most reputable producers will include a chemical analysis that shows the beta-glucan content of their product. These not only ensure the quantity of beta-glucan in the product but they also are good indicators of other fungally derived content such as Cordycepin. Ideally these tests are tied to specific batch numbers allowing you to know exactly what is in the product. Some companies even go as far as to verify their results via multi-lab testing. 

While beta-glucans are a type of polysaccharide, polysaccharide content may not always be a good representative of the beta-glucan content. This is because some products may contain other polysaccharides like starches derived from grains. 

A high-quality product should contain at least 10% beta-glucans and less than 4% starch content. Supplements should contain no more than 5% greater total polysaccharide content than beta-glucan content. You should also check the ingredient list to ensure that beta-glucans are not originating from yeast, oats, and other natural sources of beta-glucans which will not have the same effect 

Some producers may go as far as including other fungally-derived compounds that can be great indicators of quality. Others may include quantities of heavy metals and other toxins to show that they are within the safety thresholds for these components. This can be reassuring information as some products may be exposed to contamination during their production. If you are worried about toxic compounds you can also purchase certified organic products that undergo more rigorous regulation. 

While beta-glucans are not the only active compounds in Cordyceps they are typically the most frequently tested due to it’s relative ease. Testing for Cordycepin, Adenosine, and some of the other active compounds is more difficult and thus more expensive or inaccessible.

6. North American grown Cordyceps vs Chinese grown

There is frequent discussion about the quality of Cordyceps mushroom supplements coming from China. Some areas of China have high rates of air pollution which can negatively affect the quality of soil with unwanted pollutants and heavy-metals. But this does not mean Chinese mushroom products are bad.

China has been using mushroom-based medicine for thousands of years, long before it became popular in the west. China is the largest producer of organic Cordyceps and medicinal mushrooms in the world and grow their products from provincial areas in rural mountain provinces. 

With decades of research and usage, China produces some of the most potent Cordyceps and medicinal mushroom products on the market, and also has some of the most sophisticated extraction labs in the world.

Certificate of analysis

If you are unsure of the quality of the Cordyceps product, you can request a third party Certificate of Analysis (COA) from the producer. A Certificate of Analysis from a third party lab is important to identify the beneficial compounds in a Cordyceps product (such as Cordycepin, beta glucans, Adenosine), as well as to avoid heavy metals, pesticides and other foreign contaminants. Heavy metals that are typically tested for range from arsenic, cadmium, lead, and mercury.


Always look for organic Cordyceps supplements. This verifies that the cultivation process is compliant and is grown without using harmful chemicals, herbicides, and pesticides.

Look for the widely recognized stamp of quality and integrity of a Certificate Organic from the regulatory body, the United Stated Department of Agriculture (USDA) organic certification for the United States

Cordyceps Supplements Types in the United States

Image source: Real Mushrooms

Cordyceps powder

Cordyceps dried powders are made from pulverizing the 100% fruiting body of Cordyceps Militaris. Cordyceps Powders allow for the full consumption of the entire mushroom and therefore getting all the nutritional benefits as a whole-food. Powders are generally made from mushrooms that have been heated or processed in a way to break down the indigestible cell walls, known as chitin, and make the medicinal compounds bioavailable. 

Cordyceps extract

Extracts contain the individual medicinal compounds of Cordyceps without the biomass. This is done via an extraction process with hot water and/or alcohol and solvents (dual extraction). This makes small doses of Cordyceps highly potent, extremely compact, and have a longer shelf life. 

There are two different types of extracts available in the United States:

1. Cordyceps tinctures

Tinctures are liquid extracts that most often use water and alcohol solvents. They are a convenient method of consuming Cordyceps. Tinctures can be made by extracting both cordyceps militarism and/or cordyceps sinensis CS-4.

2. Cordyceps powdered extracts

Powdered extracts are the dry powdered result of extracting the individual medicinal compounds from the Cordyceps mushroom. Powdered extracts can be extracted from both the fruiting body and/or the mycelium of Cordyceps Militaris, or the CS-4 cordyceps sinensis liquid mycelium.

Cordyceps capsules

Capsules and Tablets are usually either filled with Cordyceps mushroom powders or extracts. They are the most convenient way to dose and consume Cordyceps. Buying capsules are in growing demand in the United States as they are an easy option for those already regularly taking supplements or other medications in this form.

Cordyceps coffee and tea

Cordyceps can be incorporated into hot drinks such as coffee and tea. The big benefit these products have is that they are easy to incorporate into your daily routine.

Cordyceps Tea can be purchased as tea bags containing both Cordyceps powder and dried tea herbs; leaves.

Cordyceps Coffee products are sold as ground coffee beans mixed with Cordyceps powder.

Fresh Cordyceps mushrooms

Cordyceps Militaris fruiting bodies can be consumed fresh, but they are most often sold dehydrated. These can be easily prepared by decocting in boiling water for 5-10 minutes. Alternatively, they can be added to soups or cooked in other brothy dishes.
