The standard dosage of saw palmetto is 320 mg daily. Splitting the supplement into two separate 160 mg doses does not compromise its effectiveness, explain New York University Langone Medical Center Experts.
Saw palmetto oil is an accepted medical treatment for enlarged prostate, known as BPH. Typical symptoms of the condition include difficulty urinating, weak stream, frequent urination, dribbling after urination and waking several times at night to urinate. Benefits are typically present after four to six weeks of treatment, states Langone Medical Center.
Studies have indicated very few adverse side effects, though persons with high blood pressure, liver disorders and those taking medications that affect blood pressure are advised to use the supplement cautiously, warns Mayo Clinic.
