CoQ10 and omega-3s lowers prostate PSA levels

Doctors wanted to test the ability of coenzyme Q10, omega-6, and omega-3s to alter prostate-specific-antigen (PSA) levels in healthy men with normal PSA levels, which can rise when the prostate is inflamed, enlarged, or cancerous.

In the study, researchers divided 504 healthy men with PSA levels at or below 2.5 nanograms per milliliter of blood into four groups. The men took a placebo, 400 mg of CoQ10 per day, 2,400 mg of the omega-6 GLA per day, or 4,480 mg of EPA plus 2,880 mg of DHA (omega-3s) per day, in divided doses.

After 12 weeks, while there was no change for placebo, and a 15 percent increase in PSA levels in the omega-6 GLA group, those who took omega-3s saw a 30 percent reduction in PSA levels, and those who took CoQ10 had 33 percent lower PSA levels.
