Hi,
Always see your Doctor first.
In my case (I'm nearly 60 now) it works great, I take 160mg gelpill morning and agian at dinner time.
Not all Saw Palmetto by various makers are the same, often they have other stuff in there, look for 160mg Saw palmetto as the key ingrediant, if directions say take 4 to 6 a day, then the actual dose is much to small and is full of other stuff.
Once you find a brand that works for you, stick with it. Fancy brands I looked at were not as good.
