About Shiitake

Shiitake (Lentinus edodes) mushrooms are common culinary mushrooms that possess a number of health benefits.* These mushrooms traditionally have been used to support the immune system, and there is a great deal of modern scientific research on Shiitake, too.* Our bulk Shiitake mushroom products start with USA-grown mushrooms that are Certified Organic.

Customizable & Premade Options!

You can count on Bulk Wholesale Mushrooms to provide you with the highest quality custom mushroom supplements. When you want the best quality mushroom products, you have to start with the best quality mushrooms. Trust our expertise in sourcing premium organic Shiitake from USA farmers, and our comprehensive, proprietary extraction process. Partnering with a reliable wholesale supplier can help you build trust and confidence with your customers. All our mushroom powders and extracts are made from USDA Certified Organic mushrooms.

Each batch goes through our specialized triple extraction method. That starts by fermenting the mushrooms to make polysaccharides, triterpenoids and alkaloids become more bioavailable. As next step, we do a hot water extraction because some components are only water soluble. We also do a 90-day alcohol extraction for the alcohol soluble compounds.

Each of our standard Shiitake options is exceptional, and we also offer custom formulations for those interested. Try our custom formulator and create the ideal Shiitake mushroom formula for you and your brand.


Shiitake Bulk Powders

Our farming partners have been growing and extracting mushrooms for 40+ years. We believe you can’t find mushroom powders any better than ours! We take every step possible to ensure purity and a high level of active constituents with optimal bioavailability. In raw mushrooms, the primary active constituents, the 1,3-Beta Glucans, are tightly bound to the cell walls and have a low degree of bioavailability.

To target this issue and boost bioavailability of the constituents, all of our mushrooms undergo a steam activation process that breaks down the cell walls and frees the 1,3-Beta Glucans from the chitin. We cultivate both the mycelium and fruiting bodies of the mushrooms in our products. All our mushroom powders are organically grown right here in the United States!

Shiitake Bulk Glycerites

Our Shiitake blend glycerites are alcohol-removed and triple-extracted. First, the mushrooms are fermented. This boosts the bioavailability of the polysaccharides, triterpenoids and alkaloids. Next we use a hot-water extraction to increase bioavailability of polysaccharides. Lastly, we do an extraction of 90 days in alcohol, because triterpenoids are only alcohol soluble. It takes us around 100 days to make a tincture! For our alcohol-removed glycerites, we start with a tincture then remove the alcohol and stabilize the product with USP Grade, Certified Organic vegetable glycerin.

Shiitake Bulk Tinctures

Our Shiitake mushroom tinctures are triple-extracted. First, the mushrooms are fermented to make the polysaccharides, triterpenoids and alkaloids more bioavailable. The second step is a hot-water extraction to increase bioavailability of mushroom polysaccharides. The last step of the process is a 90-day extraction in alcohol, for triterpenoids. This process takes over three months from start to finish.
