Terry. “I’ve heard saw palmetto berry extract is good for prostate function. I am 60 and I think my plumbing needs repair. What are your views or is it just a waste of money?” Harry D, Boise, ID A. Dear Harry: Saw palmetto berry extract has been clinically studied by doctors in Europe for support of the prostate. I believe there is sufficient evidence to justify its use to support proper prostate function. If you are having symptoms such as frequent urination through the night, a small caliber of stream, delayed emptying and excessive dribbling, saw palmetto berry has been effective for eliminating or reducing many of these symptoms. I would visit your physician for a physical check up to rule out prostate cancer. Usually taking 160 mg of saw palmetto twice a day has been very beneficial for most men. Give yourself 30 to 60 days before you determine how effective it is.
