NK cell activity was compared before and after 6 months of BioBran intake in 25 cancer patients with progressive disease, who received chemotherapy, surgery, and/or hormone therapy. Although a large difference in the baseline activity was observed between patients, all patients demonstrated an increase in NK cell activity after BioBran intake.
