Saw Palmetto also has the added benefit of helping to stop hair loss. It works similar to the active ingredient in Propecia that reduces DHT production. Propecia was originally intended as a prostate drug.
There has been some studies showing CoQ10 working with prostate problems. But it's odd, it doesn't work like a drug, but after taking it for 90-120 days, suddenly PSA drops dramatically and BPH declines.
I have started taking Saw Palmetto, 52, so I'm still early in my geezerdom.
DHA, EPA and a good otc NSAID are also recommended. Did absolute magic for my mutt.
