Mushroom Wisdom, Inc. (MWI) announced today that its Maitake D-Fraction® Pro 4X (formerly Grifron®-Pro Maitake D-fraction®), the company's flagship product, has been officially approved by the China FDA as the imported health food for immune enhancement.* The registration Number is GuoShiJianZi J20110013.

Maitake D-fraction®, a bioactive proteoglucan (protein-bound beta-glucan) from Maitake mushroom, developed by Mushroom Wisdom, Inc., is known to be immune-enhancing supplement product on the market.* The first product "Maitake D-Fraction® Pro 4X" was launched in the U.S. in 1995.

President & CEO Mike Shirota said, "We knew that it is extremely difficult for foreign products to get approved as official health foods by the Chinese government. With our D-Fraction® officially approved we should be able to demonstrate the legitimacy of original D-Fraction in the vast Chinese market, where a number of inferior copycats have held sway. Chinese consumers will ultimately benefit because our authentic D-Fraction product will now be easily available to them."

Mushroom Wisdom, Inc has already established a joint-venture company in Hangzhou, China by the name of Hangzhou Zhengshu Health Food Co., Ltd., and the term "D-Fraction" has been registered as its trademark. The genuine Maitake D-Fraction® product is finally available in China exclusively through the J/V company.
