Searching for some answers

Hi everyone, this is my first time to this forum. I am trying to find some info about coral calcium and the whole scandal with Barefoot. I work in a small health food store and there is a nice old lady who comes in who is battling cancer. She asked me to look up some info about coral calcium and she was wondering about the bad things said about Barefoot and his partner(s). Can someone please shed some light for me? Also, is coral calcium beneficial for someone with cancer? I really don't have much knowledge in this area. Thank you for taking the time to help. Tweet
