Looking to buy Reishi mushrooms in the United States? This guide will help you find the best quality products for this unique mushroom and ensure you’re getting the highest quality Reishi product.
Countless studies show that Reishi mushrooms (also known as Ganoderma lucidum or ganoderma lingzhi) have beneficial health properties, but consumers should be aware that not all Reishi products are equally effective. According to a study published in the journal “Scientific Reports”, a whopping 74% of Reishi products didn’t contain what was promised in the packaging. This not only means many consumers are not getting their “bang for their buck”, but they will not reap the health benefits offered by high-quality products. This also makes choosing the right products particularly important for those hoping to use Reishi to help treat serious illnesses.
There are many options for choosing high-quality Reishi and medicinal mushrooms in the United States. If you are comparing different Reishi products you can follow the tips mentioned in this guide to ensure that you are getting a high-quality product, as well as our product recommendations for top producers of Reishi supplements.

Health benefits of Reishi
Reishi mushroom, also known as Ganoderma lucidum or Lingzhi, is a medicinal fungus with wide reported health-boosting effects. The mushroom has been a staple in Eastern medicine and is equally popular in the world of medicinal supplements. People interested in purchasing Reishi mushroom supplements must be aware that only a good quality one can give you the purported benefits.
Several molecules, including triterpenoids, polysaccharides, and peptidoglycans, may be responsible for the health benefit such as:
- Improves immune function
- May help in adjunct cancer treatment
- Helps with depression
- Reduces fatigue
- May improve heart health
- May help with fiabetes
Other Medicinal Properties
- Ganoderma and its extracts contain high quantities of antioxidant and antimicrobial activities. (Ferreira, 2015)
- Ganoderma was shown to help improve learning and memory in mice. (Want, 2004 – Khatian, 2019)
- Ganoderma has prebiotic properties and may help treat obesity. (Delzenne, 2015)
- Ganoderma has been shown to have good potential as an anti-inflammatory supplement. (Wu, 2019)
- Ganoderma species may help promote sleep quality and length. (Cui, 2012 – Yao, 2021)
Our selection process for the best Reishi supplements
1. Mushroom fruiting body on the label
When choosing a product one of the first things to analyze is to see if it is made from mycelium or the mushroom fruiting bodies. If you are not familiar with the term, just think of mycelium as the white spider web-like “roots” of the mushrooms, whereas the fruiting bodies are the structures we eat and know as mushrooms.
While fruiting bodies are traditionally what has been used in medicine, today many products contain fungal mycelium instead of fruiting bodies. While mushroom mycelium has been shown to be medicinal there are issues with their use in medicinal supplements. Mostly it is that mycelium-based products actually contain relatively small quantities of fungal biomass and instead contain starches and other compounds from the grains that the mycelium is cultivated on. Because of this, these supplements contain high quantities of starches (which many try to eliminate from our diet anyway!) and low quantities of the medicinal compounds we are after.
How to know if your supplement is made from mycelium or fruiting bodies
- Check the label! Ingredients in mycelium products will likely list grains (like brown rice, wheat, barley, etc.) and will have a high quantity of carbohydrates.
- Producers will often mention if they are made from fruiting bodies. It should say “Made with 100% Whole Fruiting Bodies” or something of the like.
It should be noted that dozens of studies have been conducted on medicinal mushroom mycelium that show it does indeed have strong medicinal properties. The biggest difference is that scientific studies usually use pure mycelium that contains no extra grains or fillers. In these cases, fungal compounds are much more concentrated than grain-based mycelium products typically sold in the supplement industry.
2. Ideal extraction methods
Medicinal mushrooms are most often consumed as extracts. These concentrate the number of medicinal compounds in an easy-to-consume product. They are ideal for consumption not only due to their potency but also because of their high bioavailability and ease of consumption. Other forms of consuming Reishi may be more laborious to prepare and not fully extract all the desired compounds.
Dual extraction is best
In the medicinal mushroom world, the most common extractions are known as “dual extractions”. They are “dual” because of the fact they use both alcohol and water as solvents. This ensures that all water-soluble and alcohol-soluble compounds end up in the final product.
- Water is used for extracting the polysaccharides known as beta-glucans. These are found in high quantities in Reishi mushrooms and are one of the most medicinal components it contains.
- Beta-Glucans are compounds found ubiquitously within the fungal kingdom. They are a type of polysaccharide that occurs within the cell walls of the mushroom and have been shown to exhibit a wide array of health properties. The benefits of beta-glucans are diverse but usually tied to improved immune function, digestive health, improved well-being, and anti-cancer properties.
- Alcohol is used for extracting triterpenes present in Reishi mushrooms. In the case of tinctures, it also helps as a preservative that increases the shelf life of the mushroom.
- Triterpenes are alcohol soluble compounds that exhibit a wide array of medicinal properties. Over 50 different triterpenes occur in Reishi mushrooms, the most common being Ganoderic acid. Another important triterpene is lucidenic acid. These are shown to be immune-modulating, anti-cancer, and help with a variety of chronic diseases.
The extraction ratio is something that is commonly mentioned in medicinal mushroom products. They may say something like “10:1 Reishi Mushroom Extract”. What this ratio represents is that the producer used 10kg of Reishi mushrooms for every 1kg of extract they end up with. The higher the ratio usually suggests the more potent the product.
It should be noted that a 10:1 product may not necessarily contain twice the active components of a 5:1 product. This is because this ratio does not necessarily represent the effectiveness of the extraction or the quality of the original materials. It is also important to consider that the more potent the extract doesn’t always reflect the effectiveness of the product. This is because higher doses may not necessarily always be more effective in specific treatments. The only real way to compare the potency of unique supplements is by a chemical analysis that measures the number of beta-glucans, triterpenes, and other fungal-derived compounds.
Extracts can also be found in tinctures or powders. Powders tend to be much more potent by weight because they contain none of the liquids originally used in the extraction process.
3. Reishi mushrooms should be bitter
While bitter flavors are usually considered unpleasant they are often characteristics of many medicinal compounds. This is the case for the triterpenes present in Reishi mushrooms. Since Reishi generally refers to a wide group of mushrooms in the classification Ganoderma the number of triterpenes in the original biomass used for extraction can vary. Improper extraction methods can also result in low quantities of triterpenes.
For this reason, your Reishi products must have a bitter taste. If you are uncertain of the quality of your extract you can taste it for bitterness. A high-quality Reishi product should quickly stimulate a bitter flavor on your tongue within moments of tasting. All you need is a tiny bit to get the bitter flavor. If your product is sold within a capsule you can open one up to test for bitterness. While the bitter flavor may be unpleasant it is not something you should worry about or be concerned of
4. Beta glucans on the label
Some of the most reputable producers of Reishi supplements test the number of beta-glucans in their products. If this is the case then they will usually display this information on the label. As previously mentioned, these are some of the most important compounds present within the mushrooms.
While Beta-Glucans are a type of polysaccharide consumers should beware of not judging their products solely on polysaccharide contents that may be mentioned on the label. This is because some products may contain polysaccharides originating from plants and thus will not have the desired medicinal effect. It should also be noted that certain plants like Oats, also produce beta-glucans that are not as effective.
If your products contain both the information of beta-glucans and polysaccharides make sure that the polysaccharide content is no more than 5% higher than beta-glucan content. Also, be sure to avoid products that may contain plant or yeast-based beta-glucans as these are not going to have the desired effect.
5. North American grown Reishi vs Chinese grown
There is frequent discussion about the quality of Reishi 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 Reishi 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 Reishi and medicinal mushroom products on the market, and also has some of the most sophisticated extraction labs in the world.
6. Certificate of analysis
If unsure, ask the producer for a third party Certificate of Analysis (COA). A Certificate of Analysis from a third party lab is important to identify the beneficial compounds (eg. beta-glucans, triterpenes, ergosterol) in the Reishi product, as well as to avoid heavy metals and other foreign contaminants. Heavy metals that are typically tested for range from arsenic, cadmium, lead, and mercury. Quality Reishi mushroom producers should be able to provide this upon request, or better yet, publicly display this on their website.
Always look for organic Reishi 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
Reishi products available in the United States
Reishi dried powders are made from pulverizing the 100% fruiting body. Reishi Powders are often called ‘full-spectrum’ as you get the ‘full entourage effect’ of consuming 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 make the medicinal compounds bioavailable.
Extracts contain the individual medicinal compounds of Reishi 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 Reishi highly potent, extremely compact, and have a longer shelf life. With an extract, however, you don’t receive the full benefit of consuming the mushroom as a whole food which can exclude some beneficial components.
There are two different types of extracts available in the United States:
1. Reishi tinctures
Tinctures are liquid extracts that most often use water and alcohol solvents. They are a convenient method of consuming Reishi.
2. Reishi powdered extracts
Powdered extracts are the dry powdered result of extracting the individual medicinal compounds from the Reishi mushroom. Powdered extracts can be extracted from both the fruiting body and/or the mycelium.
Capsules and Tablets are usually either filled with Reishi mushroom powders or extracts. They are the most convenient way to dose and consume Reishi. 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.
Reishi coffee and tea
Reishi 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.
Reishi Tea can be purchased as tea bags containing both Reishi powder and dried tea herbs; leaves.
Reishi Coffee products are sold as ground coffee beans mixed with Reishi powder.
Fresh Reishi mushrooms
Reishi is a tough and woody mushroom. It cannot be cooked up like the edible mushrooms you may be more familiar with. In most cases, fruiting bodies should be cooked in simmering water for at least 20 minutes, although three to four hours is most recommended. You can buy fresh Reishi mushrooms as whole fruiting bodies at speciality farmers markets across the United States.
