Since this herbal product is not regulated by the US Food and Drug Administration (FDA), empirical claims or benefits are hard to come by. It may be just a nostrum, but many middle-aged men consider it helpful for prostate function or flow.
Manufacturers' recommended dosages are usually one or two capsules per day. Common formulations include 100 mg per capsule for saw palmetto from the berry portion only, or around 500 mg from the overall plant, sometimes including some berry-only derived saw palmetto and other additives such as pygeum and pumpkin seed.
