Product description:

ImunoBran® MGN-3 is a 100% natural product of plant origin. The active substance is a patented* arabinoxylan MGN-3 compound which contains rice bran polysaccharide fibres (hemicellulose B) obtained by enzymatic modification of the carbohydrase complex of the Japanese medicinal mushroom Shiitake (Lentinus edodes - edible lentin).

Arabinoxylan is a compound found in large quantities in herbs such as rice germ, grains and wheat. It is the main component of the hemicellulose that forms the cell wall. It is a type of dietary fibre. Recent research has confirmed its importance in digestion and absorption of nutrients, its role in healthy excretion and its effect in increasing the number of beneficial intestinal bacteria. In addition to various dietary fibres, 1 kilogram of rice bran also contains 3-5 grams of hemicellulose B, which is considered to be an essential immunity-enhancing compound.

When the body is stressed or in a diseased state, the immune system can become overloaded and the activity of these protector cells becomes sluggish. This is often compounded by medical treatment - such as chemotherapy in the case of cancer - which further depresses the immune system. A weak immune system is less able to prevent cancer cells and infections from taking hold and spreading in the body.

It is extremely important to both disease prevention and disease treatment, therefore, to optimize the immune system, and especially NK cell activity, as these cells, which comprise 15% of the white blood cells, are considered the "elite troops" of the immune system, and any rise in their activity can increase the chance and speed of recovery. This is why research into immunomodulators often focus on this single parameter of NK cell activity: it is easy to measure in a laboratory with a 51Cr-release assay test and it gives a good indication or "snap shot" of overall immune system strength. Most of the research papers done on ImunoBran® MGN-3, therefore, involve extensive NK cell activity testing, and it has been shown that ImunoBran® MGN-3 can stimulate sluggish NK cell activity by as much as 300% or more.

ImunoBran® MGN-3 can also increase depressed T cell and B cell activity by 250% and 200% respectively, as well as other factors of the immune system such as TNF. And it can do this without any toxicity or other adverse side effects (unlike synthetic cytokines currently used by oncologists, such as interleukin-2, which can be extremely toxic).

Main properties of the ImunoBran® MGN-3 product:

  • It is easily digestible and absorbable.
  • The effect is felt very quickly.
  • It is absolutely non-toxic and without any side effects.
  • Its effects are fully tested under clinical and laboratory conditions.
  • It is made up of 100% natural, genetically unmodified products.
  • It is also suitable for vegetarians.
  • It is manufactured using a special patented technology.


As a purely natural product, it has no side effects. Of course, the only contraindication to taking ImunoBran® MGN-3 is if you are taking immunosuppressive drugs. It is clear that if the disease you suffer from requires you to reduce your immunity, taking products that stimulate the immune system would be counterproductive. In any case, it will be necessary to consult a doctor!


Store in a cool, dry place. This food supplement should be kept out of the reach of small children.

How to use:

Press the tablet out of the blister pack and swallow it with sufficient liquid. It is recommended to take with a meal.

When using ImunoBran® MGN-3, it is necessary to increase the fluid intake (about 0.5 litres per 15 kg of weight) for a better leaching of toxic substances from the body. Water or tea (green mint, nettle, birch or chamomile leaves) is best.

A nutritional supplement should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.

Please note that ImunoBran® MGN-3 is a dietary supplement, not a drug. It is an effective part of another treatment.
