What are Reishi Mushrooms?

Reishi mushrooms (Ganoderma lucidum, G. lucidum, or lingzhi) are simply referred to as Reishi mushrooms. These healthy and medicinal mushrooms naturally grow in humid regions of Asia. 

From a like-treats-like approach, Reishi mushrooms look like the shape of a kidney. For this reason, Reishi have traditionally been used to help support kidney health and associated health issues.  

Also known as Mushroom of Immortality, there are many potential benefits of taking a Reishi mushroom supplement. Most people use Reishi as a supplement because it tastes bitter as a food.

Criteria for Picking the Best Reishi Mushroom Product

Dietary supplements, including Reishi mushroom supplements, are not all created equally. The ideal Reishi dietary supplements will display the following on labels or in product reviews: 

• Organic mushroom product
• GMP-certified or third-party tested
• Contains primarily the fruiting body and spores
• Does not contain the mycelium or contains minimal mycelium

Best Reishi Mushroom Supplement Brands

When reviewing all types of Reishi mushroom supplements, a common problem comes up: many brands use a lot of mycelium in their products. The reason this is a problem is that the mycelium is the mushroom root system and doesn’t contain much of the active mushroom compounds.  

For this post, all of the Reishi mushroom supplements contain the fruiting body of the mushroom.

Real Mushrooms Reishi Capsules

Real Mushrooms Reishi Capsules are made with 100% organic Reishi mushrooms that are dual extracted from steam and alcohol. This mushroom brand gets great reviews and is distinct because it is one of the only brands that does not contain any mycelium. It contains the active compounds with the fruiting body of Reishi. This brand is also scientifically verified for its active polysaccharides content and for its beta-glucan content. With 3rd party testing, this is a great mushroom to try.

Verified for purity and for its high levels of active compounds.

Its reviews are higher than most for actually making people feel a noticeable difference in health and well-being. The other great thing about Freshcap is that they are solely a mushroom company and they grow all of their own.

Double Wood Supplements Reishi Mushrooms

Another reputable brand of Reishi mushroom supplements is called Dobule Wood Reishi Mushroom Extract. Each 1,000mg of Double Wood’s extract is equal to other brands of 4,000mg of Reishi mushroom powder. This brand is quite the bargain too, with 150 day supply per bottle and almost a half year supply for only $19.95 at the time of this post. Contains both the fruiting body and the mycelium.

Nutricost Reishi Mushroom Powder

Nutricost Reishi Mushroom powder is highly rated and is also certified organic. It also is a stronger concentration of Reishi than most at 1000 mg per scoop. However, the label doesn’t disclose which part of the mushroom is included in the supplement and the capsule form of this brand is mycelium only.

Still, Nutricost Reishi Mushroom supplement reviews get very high ratings and for that reason, it is listed here. 

Side Effects of Reishi Mushrooms

Reishi mushrooms are generally recognized as safe but if you are allergic to Reishi mushrooms, or other mushrooms, you should avoid using Reishi supplements.
