MaitakeGold is the purest and most potent Maitake extract ever developed by Dr. Hiroaki Nanba, PhD., the inventor of the original Maitake D-Fraction. This newly patented extract, a more refined and more potent version of his earlier D-Fraction, is the only Maitake extract that carries his personal endorsement, meets his exacting standards, and matches the quality of the materials used in his many years of research on Maitake polysaccharide fractions.

MaitakeGold is 25% more concentrated than the other leading Maitake beta glucan product on the market and is extracted from a unique strain of Maitake, organically grown by the Yukiguni Maitake Company of Japan. All of Dr. Nanba's research on D-Fraction and his new MD-Fraction have been conducted solely with materials extracted from this unique and potent strain of Maitake.
