Organic and non-GMO

By choosing an organic mushroom supplement, you are ensuring that your body is not getting any added chemicals, pesticides, or synthetic fertilizers during the growing process.  The whole point of taking a mushroom supplement is to provide your body with health benefits, not to add toxins.

There are many medicinal mushroom companies out there today. Brands that provide a satisfaction guarantee are a good assurance of a company’s reputation.

Many mushroom companies now also have sustainable harvesting methods, which means they are grown in a way that adds back to the environment, not 

Uses healthy extraction methods

Mushrooms should not be processed with solvents, only steam.  Certified organic brands should use only natural extraction methods like steam extraction. 

Contains the fruiting body

The fruiting body of fungi is known as the mushroom, which contains most of the active compounds that act as the medicinal part. It’s a good idea to choose a mushroom brand that contains the fruiting body or is full-spectrum.  

Full-spectrum contains the fruiting body, mycelium, spores, and primordia (baby mushrooms).  

A few good brands are mycelium only, but be sure to check reviews to make sure the products have the intended purity and quality. 

Growing conditions are optimal

By mimicking natural growing conditions or using natural growing methods, mushrooms will have more active compounds.  

That is why Medicinal Foods mushrooms stand out for quality the most because they carefully replicate natural growing conditions.  Medicinal-Foods mushrooms also contain 95% pure mushroom powder, whereas many brands contain a fair amount of the rice or grain growing medium. 

Medicinal Mushroom Health Benefits

Research is becoming strong in regards to the benefits of mushrooms for our health and for the health of the environment. 

Medicinal mushroom species range from Chaga to Turkey Tail and Reishi to Cordyceps and Maitake. While they all have distinct compounds that are supportive of a healthy immune system, each kind has unique roles in the body.
