Saw Palmetto supplements are popular among men who are interested in healthy prostate function. As men age, they sometimes experience health problems related to their prostate gland. Dietary factors, as well as normal aging, can cause the prostate gland to become inflamed. As it becomes inflamed, it swells in size, putting pressure on the urethra. This can result in symptoms that may include difficulty urinating or painful urination. Saw palmetto contains natural compounds that may help to support prostate health by protecting prostate cells from DHT (dihydrotestosterone) which can cause the prostate to become inflamed, interfering with normal prostate health and function. Mason Natural Saw Palmetto is a whole herb formula providing 500 mg of saw palmetto fruit per capsule. Promotes Healthy Prostate Function, DHT Blocker, May Relieve Urinary Frequency Issues.
