Description
What is BioBran MGN-3?
BioBran MGN-3 is a natural dietary supplement made from water-soluble dietary fiber (hemicellulose B) extracted from rice bran. This fiber contains Arabinoxylan, a compound of the sugars xylose and arabinose, known for supporting immune health. Moreover, its low molecular weight helps the body absorb it easily. As a result, BioBran MGN-3 has become a trusted choice for those seeking a natural way to strengthen immunity.
The supplement is created by partially digesting the carbohydrate part of shiitake mushroom mycelia. Consequently, this process produces a rice bran Arabinoxylan derivative with strong immunomodulatory properties.

Alexander Sergeyevich, Azerbaijan –
First, you consult a doctor for treatment.
It’s an excellent immunomodulator and dot well in combination therapy. If other immunomodulators or immunosuppressive therapy was prescribed, don’t take Biobran, or ask your doctor to consider an alternative.
Many doctors know about Biobran because it’s just just in Russia. I have known about it, but I can’t prescribe it to patients (by law), even if I’d like to. We get for prescribing dietary supplements, no matter how good they are; that’s the way our own medicine.
