MGN-3 ARABINOXYLAN
What is BioBran MGN-3?
BioBran® MGN-3 is a food supplement based on modified rice bran. The raw material contains complex polysaccharides. Enzymatic processing produces smaller, water-soluble arabinoxylan structures. The reference book behind this page describes the product’s development since the early 1990s and summarises laboratory, animal and small human studies.
Enzymatic hydrolysis
Processing with enzymes from Lentinula edodes mycelium.
Arabinoxylan complex
A standardised MGN-3 complex.
SCIENTIFIC BACKGROUND
Research on BioBran MGN-3
The research summarised in the book focuses on markers of innate immunity, especially natural killer (NK) cells, macrophages and cytokine signalling. The evidence comes from different study designs and should not be treated as equally strong.
NK cells
Laboratory and small human studies examined changes in NK-cell activity after MGN-3.
Macrophages
In-vitro research explored phagocytosis and macrophage activation.
Cytokines
Other studies looked at signalling molecules such as interferons, TNF and interleukins.
Important: The book contains many older, preliminary studies and case reports. They do not support a promise of cure. BioBran is not a medicine and does not replace diagnosis or medical treatment.

Frequently asked questions
What is arabinoxylan?
Arabinoxylans are plant polysaccharides found in cereal cell walls. In BioBran they are derived from rice bran.
How is BioBran produced?
Rice bran is partially hydrolysed with enzymes from shiitake mycelium, producing smaller, water-soluble components of the MGN-3 complex.
What does the research investigate?
Research mainly addresses immune laboratory markers such as NK-cell activity, macrophages and cytokines. Some studies are in vitro or animal studies, while several human studies are small or older.
Can BioBran replace medical treatment?
No. BioBran is a food supplement. Seek medical advice in case of illness, pregnancy, breastfeeding or regular medication.
Which format should I choose?
Tablets contain 250 mg each; sachets contain 1000 mg each. Follow the label, recommended use and any advice from your healthcare professional.
Food supplements should not be used as a substitute for a balanced, varied diet and a healthy lifestyle. Do not exceed the recommended daily intake. Keep out of reach of children.
