Saw Palmetto (Serenoa repens) Berries are especially beneficial to men over the age of 45 seeking to promote an active and healthy lifestyle.  Studies have shown (but not proved) that saw palmetto may be helpful to men suffering from prostate problems and male pattern baldness.  There is also no indication of negative side effects from taking saw palmetto berries in normal dosage.  For more information about saw palmetto and its benefits please go to Medline Plus (a service of the US National Library of Medicine and the National Institutes of Health).
