Maitake Gold 404™ is a proprietary maitake extract developed by Dr. Hiroaki Nanba, the world's leading authority on maitake. In 1984, Dr. Nanba identified a fraction of maitake that possessed a significant ability to stimulate white blood cells known as macrophages (literal translation "big eaters"). Dr. Nanba termed his discovery maitake D-fraction. Further purification of the D-fraction yielded the MD-fraction (U.S. Patent #5,854,404), which is even more bioactive than the D-fraction. Any research references to the D-fraction also apply to the purer and more potent MD-fraction.*
