PSA is a protein that is produced by the prostate gland. Prostate cancer patients often have increased PSA levels, although cancer may occur with any PSA level.
CoQ10 is a fat-soluble antioxidant that serves as a co-factor in oxidative respiration for the Krebs cycle and the electron transport chain. CoQ10 levels decrease with age and have also been observed to be low in patients with cardiovascular diseases, muscular dystrophies, Parkinson's disease, cancers, diabetes, and HIV/AIDS.
The recent study included 504 healthy men with serum PSA levels lower or equal to 2.5 nanograms per milliliter. The participants were randomly assigned to one of four groups. Each group corresponded to a different supplement, either omega-6 fatty acids, omega-3 fatty acids, CoQ10 or placebo. The men took two pills daily for 12 weeks.
Researchers took serum PSA levels prior to and after the study. The groups taking omega-3 fatty acids and CoQ10 had significantly lower PSA levels, compared to before supplementation. Conversely, the group consuming omega-6 fatty acids experienced a significant increase in PSA levels.
