Strengthening the Immune System has never been more urgent: How ImunoBran (Biobran) can help.
By Linda Vezzoli (Nutritional Therapist)
Pet IMUNE stimulates the immune system by increasing the activity of lymphocytes - B cells, T cells and especially natural killer (NK) cells. B cells produce antibodies, while T and NK cells destroy cells infected with viruses or bacteria, as well as cells that have become cancerous. A single NK cell in optimal condition can kill up to 27 cancer...

Depression is increasingly recognized by researchers as a condition rooted in chronic inflammation. Inflammation occurs throughout the body due to unmanaged stress, activation of fight-or-flight thoughts and feelings, as well as inflammatory causing foods and other substances. Some cytokines and other inflammatory messengers such as CRP, IL-1, IL-6...
Today, breast cancer affects 1/8 women!
Originating in the United States, "Pink October" is a tradition that has been going on for over 28 years. The symbol of this event is the pink ribbon, pink, a feminine colour, soft, joyful and evoking good health. This international campaign aims to raise awareness of breast cancer screening.
Medicine from the Far East has many followers today. Almost everyone today knows what alternative medicine, acupuncture or chi life energy are. Most people, however, only associate them with China. In a way this is justified, as Traditional Chinese Medicine (TCM) originated in the Middle Kingdom, but its manifestations can be found throughout the...
Vitamin D is also called the sunshine vitamin because one of its main sources in our bodies is skin synthesis, which is made possible by exposure to the sun. As an organic compound, it has been the subject of much research and is studied extensively by scientists. In laboratory nomenclature, it is coded as 25(OH)D3 and its recommended blood level...

Biobran MGN-3 is a Japanese immunomodulator derived from rice bran. This food supplement was developed in the mid-90s by Professor Ghoneum in the US and Dr Maeda in Japan to help support immune function, especially for patients with immune systems compromised by disease and/or toxic treatments. It is a pharmacologically active natural product, sold in 49 countries, and it is safe and non-toxic (1).
The rice bran extract in Biobran has been broken down by an enzyme derived from Shiitake mushroom. The main chemical structure of Biobran (MGN3) is arabinoxylan. Its low molecular weight enables it to be absorbed into the small intestine and then passed into the bloodstream where it helps to activate key immune cells such as dendritic cells (9, 10), B lymphocytes, T lymphocytes and Natural Killer Cells (11, 12, and 13).
There are studies to support its usefulness as an adjunct for those undergoing treatment for Rheumatoid Arthritis (2), HIV (3), Diabetes type 2 (4, 5), IBS (6), asthma (7) and Hepatitis (8) but the research has been ostensibly focused on raising immunity for those undergoing treatment for cancer. The number of peer-reviewed studies on this natural compound is exceptional (59 so far), allowing doctors and practitioners to recommend it with confidence. It is well established to raise Natural Killer Cell activity (11, 12, 13), which research has demonstrated to have an important role in immune defence against cancer. A 2017 study showed that Biobran/MGN-3 induces a significant increase in NK activity which may increase resistance to viral infections and cancers in the geriatric population.(15). A 2012 study done on healthy adults, it was also concluded that Biobran 'may not only help to destroy tumor cells and viruses directly, but also increase the activity of immune cells, thereby optimizing the immune system, especially natural killer cells, which can increase the chance and speed of host recovery'. (14)
A 2020 study showed that MGN-3 effectively attenuated radiation-induced changes in the intestinal epithelial mitochondrial function, oxidative stress, inflammatory response, apoptosis, intestinal permeability and barrier function in mice, (16) showing a promising use of Biobran for the protection of our gut health, which is vital for immune health.
Research has also shown that, provided BioBran MGN-3 is regularly included in the diet, this stimulation of the immune system need not decrease over time. This lack of attenuation (or hyporesponsiveness) with prolonged use is extremely unusual for immunomodulatory substances and means that BioBran MGN-3 continues to be an effective supplement over an extended period of time - which is important for long-term treatment plans. NK activity usually peaks around 1 or 2 months after being on a high dose, after which it can be maintained with a smaller maintenance does. The speed at which this peak is initially reached is dose dependant.
Generally, 500mg to 1000mg is recommended per day although, initially, some practitioners will recommend 3000mg a day for the first month or two, and during times of severe immune compromisation.
Clinical data to support Biobran:
There are 59 peer-reviewed published papers on Biobran and some feature on Pubmed. A more comprehensive list of scientific research on Biobran can be found on www.biobran.org
