Saw Palmetto is one of the most commonly used herbs in the world.
You read some things online now about people being paranoid about it and its most commonly the same people that are terrified of finasteride that are scared of Saw Palmetto.
I've worked in this industry on one side or the other for almost 30 years and worked on the raw material side for over 20, and I before the finasteride paranoia that spilled over to Saw Palmetto, I had never heard of a single issue with Saw Palmetto. Literally never one single person that had an issue with it.
I'm not saying that there aren't people that do, but its less than 1% and if you didn't have any side effects with finasteride, then I think you have zero to worry about with Saw Palmetto.
I've used it almost daily since I've turned 40 and I'm 46 now.
