Biobran / MGN-3 / Arabinoxylan Rice Bran
Rice-bran derivative modified with shiitake enzymes and promoted for natural-killer-cell activity. Biobran/MGN-3 is sold as a food supplement and claimed to support NK-cell activity. Cancer Research UK says there is not enough reliable evidence to support it as a cancer treatment, although some lab/animal and limited clinical research exists. PROS May have immune-marker research interest, especially NK-cell activity.
