Query: careful with one of the ingredients

Ok, first of all, this multivitamin is very complete, it even has things others don't, which is really good. the problem is that it has too much of some things. If you look at the ingredients, you'll see that these pills contain saw palmetto which is a plant used for prostate health. Some people claim it also helps hair regrowth. However, one of the side effects of it is that it can cause erectyle dysfunction! Believe me, I personally experienced this while taking these pills. I completely lost my sexual drive. In addition to that, it also caused insomnia! Do your own research and you'll confirm what I'm telling you. I could not even finish the bottle. Be careful with saw palmetto.
