Maitake Mushroom History
Maitake is a choice edible that only recently has been utilized for its medicinal properties. Today it is extensively cultivated on sawdust substrates. During the 1990’s Japanese scientists led by Dr. Hiroki Nanba carried out extensive research demonstrating the activity of Maitake beta-glucans as immune system potentiators. Their research identified and commercialized a concentrated beta-glucan called D-fraction or MT-1.
Maitake Mushroom Uses
Proudly Made in China
In 1996, CEO and Founder of Nammex, Jeff Chilton organized organic mushroom production in China. That initiative paid off and today all Nammex mushrooms are grown or wildcrafted deep in the mountains of China by our Certified Organic production partners.
Not All Medicinal Mushrooms Products are Created Equal
US lab-grown Maitake is mycelium grown on grain. Analysis has shown that US Maitake mycelium on grain has low levels of beta-glucan and very high levels of starch. Nammex only uses 100% organic fruiting bodies which are rigorously tested and guaranteed for active compounds.
