BioBran is a functional food manufactured using a water-soluble rice bran dietary fiber component (hemicellulose B). Collaborative research with Prof. Mamdooh Ghoneum Ph.D. at the University of California, Los Angeles, USA (UCLA/Drew University of Medicine) on rice bran dietary fiber components has led to the discovery and establishment of processing and manufacturing methods of a food that optimally modulates the innate immune function of the body. It was subsequently demonstrated that BioBran has not only an immunostimulatory effect but also an immunomodulating effect. Extensive efforts to maximize its stability and taste have resulted in BioBran rice bran arabinoxylan. Currently, BioBran is widely used not only in Japan but also in more than 50 countries worldwide, and has an excellent reputation.
The condition of the body is maintained at a constant level by modulating body temperature and blood pressure, to cope with changes in the environment inside and outside the body. This mechanism is called homeostasis. In homeostasis, the innate immune system plays an important role: it eliminates foreign substances (non-self) such as pathogens, viruses and cancer cells. However, it is known that immune function deteriorates with aging, and is impaired or stimulated by a poor lifestyle such as smoking, insufficient physical exertion or an unbalanced diet, and by adverse environmental changes and pollution. Deterioration of immune function causes or aggravates infection and malignant tumors, while excessive elevation of the immune system may cause things such as hay fever, atopic dermatitis or chronic inflammation. Studies in recent years have clarified that fiber and indigestive components in food are deeply involved in the maintenance of homeostasis and immune responsiveness.
Daiwa Pharmaceutical Co., Ltd. has focused on a dietary fiber thought to have the potential to impact the immune response and developed a multifunctional food closely related to the Japanese foodstuff of ancient times, named BioBran (Rice Bran Arabinoxylan Compound).
BioBran is a functional food produced by water-soluble dietary fiber (hemicellulose B) with an enzyme derived from shiitake mushrooms.

Starch, dietary fiber, and BioBran are classified as polysaccharides.
Starch is digested by saliva, pancreatic juice, and intestinal juice, and is absorbed in the small intestine as glucose. Dietary fiber is not digested, and is excreted unchanged. BioBran is known to be partly absorbed directly in the digestive tract, entering the blood stream.It activates the Natural Killer Cells, T cells, B cells, and macrophages, either directly in the blood, or indirectly via the Peyer's patch of the ileum, BioBran plays an important role in immunomodulation (immunostimulation, anti-inflammation, anti-allergy, antioxidation processes). Overall, it is considered to enhance the body's natural healing abilities, alleviate the adverse drug reactions of chemotherapeutic agents, and improve quality of life.
