Saw Palmetto is a supplement derived from the fruit of the plant Serenoa repens. The supplement (saw palmetto) has a caloric value, as it is a concoction of fatty acids that have the ability to block an enzyme that converts testosterone into dihydrotestosterone (DHT); which is a more androgenic form and may lead to hair loss. Its effects on DHT production have also led to saw palmetto being used for relieving urinary tract infections. Nature Life Nutrition Saw Palmetto Capsules have been prepared with the finest Saw Palmetto extracts which is useful for a number of problems such as hair loss, hair fall, enlarged prostate in men, infections in the urinary tract, etc.
