Maitake Beta-Factor, Dr. Nanba’s 163mg 60 Tablets

With MaitakeGold 404® ”“ Endorsed by Leading Maitake Researcher, Dr. Hiroaki Nanba!

The maitake mushroom has a long history of traditional use, but it is only recently that modern science has made possible the creation of a highly specialized maitake product, rich in beta-glucans. Planetary Herbals now offers Dr. Nanba’s Maitake Beta-Factor, which contains MaitakeGold 404®, the only maitake extract endorsed by the world’s premier maitake researcher, Dr. Hiroaki Nanba, Ph.D.

Dr. Nanba’s Maitake Beta-Factor combines MaitakeGold 404® - a specialized beta-glucan fraction believed to have important health promoting properties - with maitake fruiting body, maitake mycelia biomass, calcium, and vitamin C. This blend offers you a Full Spectrum™ of maitake activity.

Rich Source of Polysaccharides
Maitake is a rare edible mushroom that is native to northern Japan. In Japanese maitake means "Dancing Mushroom," because people would dance for joy when they found it in deep mountain valleys. Maitake is a rich source of polysaccharides - compounds found in some plants that are increasingly recognized for their ability to support the body’s immune defenses. Maitake’s benefits are thought to be due to specific polysaccharides known as beta-glucans, which are polysaccharides bound to proteins.

Dr. Nanba’s Discovery
Dr. Hiroaki Nanba is a professor in the Department of Microbial Chemistry at Kobe Pharmaceutical University in Kobe, Japan. He has a Ph.D. in Biochemistry and Immunology from Kyoto University, and is an award-winning researcher on the benefits and activities of medicinal mushrooms. He is also the author of four books and numerous peer-reviewed articles, including key studies on the benefits of maitake.

Dr. Nanba’s research led to the discovery of the specialized beta-glucan fraction known as MaitakeGold 404®. MaitakeGold 404® represents the culmination of 18 years of research by Dr. Nanba and contains Dr. Nanba’s patented maitake mushroom extract, the most therapeutically potent and effective maitake extract ever developed by Dr. Nanba for broad spectrum immune stimulation. MaitakeGold 404® is the only maitake product in North America endorsed by Dr. Nanba, who is considered by many to be the father of maitake mushroom research.

Additionally, clinical research with maitake often utilizes the mature fruiting body with a small amount of vitamin C. This is added to enhance the effects of maitake, since vitamin C has its own immuno-supporting properties. And, added to this, is the maitake fruiting body and mycelium biomass. The result: Dr. Nanba’s Maitake Beta-Factor, using MaitakeGold 404®, the only maitake fraction endorsed by Dr. Nanba.

Clinically Derived Formulas
Dr. Nanba’s Maitake Beta-Factor is part of a line of products that draw on the wisdom of traditional cultures and the new knowledge gleaned from scientific research, providing the best of what modern herbalism has to offer.
