What is BioBran MGN-3?

BioBran MGN-3 is manufactured using the water-soluble dietary fiber (hemicellulose B),    which constitutes about 5% of rice bran, as its main source. Rice bran hemicellulose B contains as principal ingredient Arabinoxylan, comprised of xylose and arabinose as its constitutive sugars, and has the features that its structure is included in a dietary fiber and        it has a comparatively low molecular weight. Derivative, which possesses immunoregulatory properties was successfully developed by partially digesting the carbohydrate of shiitake mushroom mycelia. This is a rice bran

Biobran MGN-3 is one of the safest supplements on the market today, with a clinical track record of nearly 15 years. It is non-toxic (LD50 >36.0g/kg) and is well tolerated. What is more, it does not have an unpleasant taste or smell, making it an easy food supplement to take.

Despite the fact that mushroom enzymes are used in the breakdown of the rice bran to make the product, the finished product is well tolerated even by those with mushroom intolerances.


Biobran MGN-3 was first developed in Japan in 1992 by Hiroaki Maeda, Director of Research and Development of Daiwa Pharmaceutical Co., Ltd, in Tokyo. Maeda's area of interest is in finding natural phytonutrient solutions for both human health and agriculture, and in the late 1980s, he turned his attention to polysaccharides, which have been known to have been known to strengthen immune response, and developed the immune system supplement, AHCC®.

After moving to Daiwa Pharmaceutical, headed by Yasuo Ninomiya, Maeda developed a new complex of short chain polysaccharides (primarily arabinoxylan and other hemicelluloses) which he gave the generic name MGN-3 after the initials of its developers — M-Maeda, G-Ghoneum, N-Ninomiya and "3" because it was a third generation product. (Mamdooh Ghoneum, Professor of Immunology at Drew University of Medicine and Science in Los Angeles, did much of the immunological research with the product.) Daiwa subsequently marketed this MGN-3 complex under the brand name Biobran.


The only (and obvious) contraindication for Biobran MGN-3 are with individuals taking immunosuppressant drugs. Obviously you won't want to boost the immune system if your doctor is trying to reduce your immune system. Apart from that, Biobran MGN-3 is not specifically contraindicated with any other drug or supplement. However, we do advise that you always check with your doctor or practitioner.
