 In the responders, blood Coenzyme Q10 levels increased five-fold with the supplementation, and lymphocyte counts increased to normal levels.In non-responders, the blood Coenzyme Q10 levels increased only two-fold, and the lymphocyte counts remained essentially unchanged.Judy and Dr. Folkers suggested that Coenzyme Q10 stimulation of immunoglobulin G antibodies and T4/T8 lymphocytes as well as possible positive effects of Coenzyme Q10 on cytotoxic T-cells might explain the observed prostate cancer regression.
