I tried them a few year's back, my surgeon actually told me to take them because I was really stressed from other health probs. I think they worked a little for the first day or two, but then I remember I kept getting a really nasty taste in my mouth. My head started feeling like tingly and I just didn't feel right, so I stopped taking them. I was going through a lot of other health probs though, so I'm not sure if the Hyland's caused it or my health issue caused it.
Just remember that any type of chemical/pill or what ever you put in you body can lead to some sort of reaction, it doesn't matter if it's natrual or not. Hope I helped some, take care.
