I was told by people at nutrition stores that this would help my sick son. Luckily within a few days I went online and read the true horror of what can happen to you if you take this so-called health suppliment, you can turn gray, permanently...since seeing was believing for me, I think it may help to see what it has done to this very kind, misfortunate woman named Rosemary...

Also, Mayo Clinic has a great site called http://quackwatch.org/
If you ever wonder about the safety of taking a product or suppliment go here to find out if it is safe.
Since I or my son could've had grey skin permanently if we would have taken this suppliment, I can't imagine the horror of this, I had to share...
