Biobran, Hemicellulose Complex with Arabinoxylane.
MGN-3 is a product made by combining rice bran with chemicals from the shiitake, kawaratake, and suehirotake mushrooms. It is used as a medicine.
MGN-3 is used for boosting the immune system to improve the body’s defenses against disease; preventing and treating cancer; and treating AIDS and other immune disorders, hepatitis, diabetes, and chronic fatigue syndrome.
The U.S. Food and Drug Administration (FDA) is seeking a court order to block the marketing of MGN-3 by Lane Labs. The complaint charges that MGN-3 is an unapproved drug product promoted as treatment for cancer and HIV infection.
How does it work?
MGN-3 might work by improving the body's natural immune system.
Insufficient Evidence to Rate Effectiveness for...
- Chronic fatigue syndrome.
- Boosting immune function.
- Preventing and treating cancer.
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
The appropriate dose of MGN-3 depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for MGN-3. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
