Important note for readers:
while many of the scientific discoveries and clinical developments listed in
this section are extremely exciting, they are stepping stones in the studies
of Diindolylmethane (DIM) and some of the other key natural ingredients in
the Berkeley Immune Support Formula. The exploration of clinical applications for Diindolylmethane is
an emerging science. Only the US FDA has the authority to recognize a compound as a
drug or therapeutic for a particular condition in the US and that only
occurs after the compound has been thoroughly studied and its efficacy
established in four consecutive human clinical trials. At this point in
time, Diindolylmethane and the other natural ingredients in the Berkeley Immune Support Formula are
regarded as dietary supplements and not therapeutics for any specific
condition by the US FDA. The Berkeley Immune Support Formula is a nutritional supplement. Statements on this website have not been evaluated by the US Food and Drug
Administration. The Berkeley Immune Support Formula is not intended to diagnose, treat, cure or
prevent any disease.

Phase I human clinical studies of Diindolylmethane (DIM) as a therapeutic
candidate for castrate-resistant non-metastatic prostate cancer patients
demonstrated efficacy. DIM has now progressed to Phase II human clinical
studies. The recommended dosage for the Phase II study is approximately 2x
the DIM concentration in Berkeley Immune Support Formula. (In order for a therapeutic candidate to receive recognition as a treatment
for a particular condition by the US FDA, it must pass four progressive
phases of human clinical trials. DIM is currently regarded as a dietary
supplement and not a therapeutic for any condition.)

Scientists demonstrate for the first time that DIM modulates four key

IFN-G is responsible for the entire immune
response system. G-CSF is responsible for White Blood
Cell production in the body. IL-6 is responsible for the body's direct
anti-bacterial response. IL-12 stimulates the growth and function of T-Cells
which help to fight off pathogens. This key publication marks the birth of a global
effort to study DIM as a potent natural therapeutic candidate for most forms of
cancer, most viral infections and most bacterial infections. According to Dr. Gary Firestone,
Director of the National Institutes of Health Cancer Research Program and
co-author of the study at UC Berkeley, "This study shows that there is a whole new universe
of molecular biology related to DIM....there are no other agents
known that can both directly promote apoptosis and
enhance the function of the immune system at the same time."
