BioBran MGN-3 is one of the most effective food supplements available for both helping the body maintain a strong and healthy immune system, and for boosting weak immune systems. Developed in Japan by Daiwa Pharmaceutical, BioBran is manufactured using a patented process to break down rice bran using enzymes from Shitake mushrooms. The resulting compound contains a unique blend of hemicellulose nutrients — including a specific arabinoxylan compound as well as other short chain polysaccharides. This unique molecular fingerprint makes Biobran significantly more effective than any other immune system supplement on the market today, giving the body its best opportunity to optimize its own natural healing mechanisms.
